First Street is a climate risk modeling company used by financial institutions, insurers, government agencies and property market participants. For commercial real estate teams, its practical role begins during screening, underwriting and portfolio surveillance. A user can examine the physical hazards associated with an address or group of properties before deciding whether to acquire, finance, insure or retain those assets. The platform sits upstream of capital allocation rather than replacing conventional engineering, environmental or insurance diligence.
Its central proposition is that historical loss information and conventional hazard maps are insufficient for decisions involving long holding periods. First Street connects property locations with models covering hazards such as flooding, wildfire and extreme heat, then translates physical exposure into decision-oriented risk information. That makes it relevant to acquisitions teams comparing markets, lenders reviewing collateral, asset managers prioritizing resilience work and insurers examining concentrations. The commercial value depends on whether the outputs can be incorporated into each buyer’s existing risk policy.
First Street is CRE-adjacent rather than a complete CRE sustainability platform. It does not replace emissions accounting, utility data collection, regulatory reporting, building certification management or decarbonization planning. Measurabl and Deepki address more of those operational ESG workflows. First Street is narrower and more specialized: it concentrates on the relationship between physical climate hazards, properties and financial outcomes. Buyers should therefore evaluate it as a risk data layer, not as their system of record for every sustainability requirement.
BestCRE’s analysis is that First Street is most compelling when a buyer needs consistent climate screening across a large property universe. Its property-level orientation and coverage of approximately 2 billion structures provide unusual scale. The announced MSCI acquisition for $120 million also validates the strategic importance of the data, although ownership by a larger financial data company does not eliminate model risk. Buyers still need to test coverage, assumptions and loss estimates against their own assets before using the results in binding investment or credit decisions.
What First Street Does and How It Works
First Street starts with a location, typically a property address or geographic coordinate, and connects it to hazard models and information about the built environment. Depending on the subscribed product and available fields, users can assess exposure to hazards including flood, wildfire and heat. The purpose is not simply to label an area as risky. The models are intended to express how risk varies by property, scenario and time horizon, helping a financial institution compare assets that might appear similar under historical maps. Portfolio users can aggregate individual results to identify concentrations by market, asset group or hazard.
The output can support several CRE decisions. An acquisitions team can introduce a climate screen before spending heavily on diligence. A lender can flag collateral requiring additional insurance review, engineering analysis or resilience conditions. An asset manager can rank properties for deeper investigation and capital planning. An insurer can examine where exposure is concentrated across a book. These uses require internal thresholds. First Street supplies modeled information, but the buyer must decide what score, expected impact or hazard level triggers escalation. The product is therefore most useful when connected to a documented governance process rather than viewed as a standalone answer.
Delivery at institutional scale typically depends on data feeds, APIs or portfolio analysis rather than manual address lookups alone. That allows risk fields to enter underwriting systems, data warehouses, asset registers and business intelligence tools. Implementation still requires location matching, identifier management, field definitions and controls for model updates. Users should preserve the model version and assessment date alongside every result because climate data can change as scientific assumptions, hazard inputs and property information are revised. BestCRE’s analysis is that First Street can standardize initial screening effectively, but property-specific engineering, insurance quotations and local diligence remain necessary wherever the financial consequence is material.
9AI Framework: Dimension by Dimension Analysis
CRE Relevance: 8/10
First Street earns an 8 for CRE relevance because physical climate exposure now affects acquisitions, lending, insurance availability, asset management and disposition planning. Property-level screening is directly applicable to collateral and investment analysis, particularly for portfolios spread across many markets. The platform can help a team decide which assets require deeper diligence before capital is committed. It stops short of a higher score because it is not a complete commercial real estate operating or ESG system. It does not manage leases, collect building utility bills, calculate organizational emissions or execute retrofit projects. Its value is concentrated in one important part of the workflow: identifying and quantifying physical climate risk. BestCRE’s analysis is that sophisticated CRE organizations will treat First Street as a specialized data source connected to broader underwriting and portfolio systems.
Data Quality and Sources: 9/10
First Street earns a 9 for data quality because its defining capability is large-scale, property-oriented climate modeling rather than a thin overlay of public hazard maps. Its breadth supports comparison across extensive portfolios and multiple physical hazards, an important advantage for institutions that need a common methodology. High-quality source coverage does not mean every building attribute or local condition is perfectly represented. Address resolution, structure characteristics, recent mitigation work and site-specific drainage can materially affect an individual assessment. Buyers should request data dictionaries, geographic coverage details, update policies, model documentation and lineage information during procurement. BestCRE’s analysis is that the data is strong enough to serve as an institutional screening layer, while consequential decisions should include checks against engineering studies, insurer information, local records and direct knowledge of the property.
Ease of Adoption: 7/10
First Street earns a 7 for ease of adoption. A climate score or hazard field is conceptually straightforward to introduce into an existing property review, and address-based analysis gives business users a familiar starting point. Adoption becomes harder when the organization moves from viewing results to making governed decisions. Teams must resolve addresses, connect properties to internal identifiers, select time horizons, determine risk tolerances and decide when a result triggers escalation. Different investment committees may also interpret modeled future risk differently. Portfolio deployment will require coordination among acquisitions, risk, sustainability, insurance, technology and asset management teams. BestCRE’s analysis is that a pilot can begin quickly if the buyer has clean property data, but repeatable enterprise use requires policy design, training and ownership beyond the initial technical connection.
Output Accuracy: 7/10
First Street earns a 7 for output accuracy. Its models can provide consistent estimates across properties and scenarios, which is valuable when historical experience alone is an incomplete guide to future conditions. Nevertheless, climate risk estimates are modeled outputs, not measurements of a future loss. Accuracy can vary by hazard, geography, structure information, scenario, time horizon and the resolution of underlying inputs. A result may not capture every parcel feature, building system, protective measure or local infrastructure project. Users should distinguish hazard, exposure, vulnerability and financial consequence rather than treating a single score as a definitive prediction. BestCRE’s analysis is that the outputs are suitable for comparison, triage and sensitivity analysis. They should not be the sole basis for rejecting an acquisition, setting loan terms or forecasting an exact property loss without corroborating diligence.
Integration and Workflow Fit: 7/10
First Street earns a 7 for integration because institutional climate data is most useful when delivered into underwriting, portfolio and risk systems through structured data or APIs. Those delivery methods can support connections to data warehouses, business intelligence platforms, asset registers and internal decision engines. The practical workload depends on the customer’s architecture and data hygiene. Commercial property names and addresses are frequently inconsistent, while loans, buildings, parcels and ownership entities may use different identifiers. Buyers also need a process for refreshing records and retaining model versions. The vendor does not publicly present a universal, plug-and-play connector catalog covering every CRE application. BestCRE’s analysis is that technically mature organizations should be able to incorporate the data effectively, but smaller teams expecting an immediate connection to every property management or underwriting product may need integration assistance.
Pricing Transparency: 3/10
First Street earns a 3 for pricing transparency because the vendor does not publish standard institutional prices, plan limits or implementation fees. A buyer must contact the company and define the desired hazards, geography, property volume, delivery method, refresh frequency and usage rights before receiving a meaningful quote. This is common for enterprise financial data, but it makes early comparison and budget approval difficult. It also leaves buyers unable to determine publicly whether a small portfolio can purchase an appropriately scaled package. Procurement teams should ask separately about onboarding, API consumption, bulk files, additional users, historical snapshots, model updates, redistribution rights and renewal increases. BestCRE’s analysis is that the absence of published pricing is a material weakness for CRE firms trying to estimate value before entering a sales process, even if custom contracting is understandable for large institutions.
Support and Reliability: 6/10
First Street earns a 6 for support. Climate modeling is technically complex, so buyers need more than account access. Effective deployment may require help interpreting methodology, mapping fields, selecting scenarios and explaining results to credit or investment committees. Public information does not establish standardized response times, named support tiers or service commitments for every customer. The quality of assistance may therefore depend on the negotiated enterprise agreement. Buyers should request a defined implementation plan, documentation access, escalation contacts, model-change notifications and commitments for addressing data questions. They should also determine whether methodological specialists can participate in validation discussions rather than relying only on commercial account staff. BestCRE’s analysis is that First Street’s institutional focus suggests support should be available, but the vendor does not publish enough detail to justify a higher score without contract-specific evidence.
Innovation and Roadmap: 9/10
First Street earns a 9 for innovation because it moves climate analysis toward property-level, financially relevant modeling at very broad scale. The approach addresses a real weakness in traditional CRE risk review, which often relies on backward-looking maps, inconsistent consultant reports or insurance information obtained late in a transaction. Connecting multiple hazards with future-oriented analysis gives investors and lenders a more systematic way to compare assets. The innovation is not that climate hazards are newly discovered, but that complex science is packaged for repeatable financial decisions across large portfolios. Buyers must still guard against false precision and avoid collapsing distinct hazards into one unexplained number. BestCRE’s analysis is that First Street has advanced the practical use of climate risk data in finance, while its long-term value will depend on transparent methods, measurable validation and continued improvement in building-specific inputs.
Market Reputation: 8/10
First Street earns an 8 for market reputation. It is recognized for climate risk research and property-level modeling used in discussions about financial exposure, insurance and real estate. The agreement for MSCI to acquire the company adds meaningful institutional validation and could expand distribution through an established financial data provider. An acquisition is not itself proof that every model performs equally well in every geography or CRE asset class. Customers should still conduct reference checks and review independent validation relevant to their hazards and markets. The vendor does not publish all customer relationships, retention metrics or implementation outcomes, so those factors cannot be assessed comprehensively from public information. BestCRE’s analysis is that First Street has stronger credibility than an early climate analytics entrant, but buyers should evaluate the product on documented performance rather than reputation alone.
Who Should Use First Street
First Street best suits institutional investors, lenders, insurers and asset managers that evaluate many properties and need a consistent physical climate risk methodology. It is particularly relevant for acquisitions teams screening pipelines, credit groups reviewing collateral, portfolio managers examining geographic concentrations and sustainability leaders adding climate risk to governance. Organizations with holdings across multiple states or regions can benefit from a common dataset that reduces dependence on inconsistent local sources during initial review.
The strongest buyer will already have clean property identifiers, a central data environment and a defined owner for climate risk policy. It will also have the expertise to interpret modeled outputs and the authority to connect findings with insurance review, engineering diligence, loan conditions or capital plans. BestCRE’s analysis is that First Street becomes more valuable as portfolio size and decision frequency increase. A buyer seeking only an occasional report for one building may find a specialist consultant or transaction-specific assessment easier to justify.
Who Should Not Use First Street
First Street is not the best primary purchase for a CRE owner whose immediate need is carbon accounting, utility collection, sustainability disclosures, tenant data or retrofit execution. Measurabl and Deepki are closer fits for those workflows. First Street can inform resilience strategy, but it does not substitute for an operational ESG platform or the teams responsible for implementing building improvements.
Small owners with a limited number of assets may also struggle to justify an enterprise data contract, particularly because pricing is not public. Buyers should avoid the product if they expect one score to settle an acquisition decision without local investigation. A property facing material exposure still requires insurance input, engineering review and examination of site conditions. BestCRE’s analysis is that organizations without a clear decision process risk purchasing sophisticated data that appears in reports but does not change underwriting or asset management.
Pricing and ROI Analysis
First Street does not publish standard enterprise pricing, subscription tiers or a public price per property. Cost is likely determined through a quote based on portfolio size, hazards, geographic coverage, access method, update frequency and permitted use, but the precise pricing formula is not published. Buyers should request a proposal that separates license fees, implementation, data delivery, additional users, usage limits and renewal terms. They should also clarify whether outputs may be stored, shared with advisers or incorporated into investment materials after the contract ends.
Analysis: a simple ROI case should use avoided diligence and improved decision quality rather than an assumed loss estimate. If a CRE team reviews 1,000 opportunities annually and automated screening saves 15 minutes on each review, that equals 250 staff hours. Multiplying those hours by the buyer’s fully loaded hourly cost produces one measurable benefit. The buyer can then add any documented reduction in consultant screening expense, while keeping hypothetical avoided losses separate. Compare the resulting annual benefit with the complete subscription and implementation cost. This calculation does not prove the product prevents losses, but it gives procurement a defensible threshold for negotiations.
Integration and CRE Tech Stack Fit
First Street fits best as a data layer inside a CRE organization’s existing architecture. Property identifiers and hazard fields can feed a warehouse, underwriting model, loan system, asset register or business intelligence dashboard through the delivery methods included in the contract. A sensible design preserves the source, model version, assessment date, scenario and time horizon rather than copying only a simplified risk label.
Implementation quality will depend heavily on address matching and governance. Teams should test apartments, campuses, portfolios with multiple structures and properties spanning several parcels. They should also define how updates affect previously approved decisions. The vendor does not publish native connectors for every CRE platform, so buyers should assume some mapping and engineering work. BestCRE’s analysis is that First Street complements existing systems well when the customer treats climate data as governed financial information, not as a detached sustainability dashboard.
Competitive Landscape
Cotality, formerly associated with the CoreLogic name, is the most natural alternative for buyers that want property data, hazard information and established links to mortgage, insurance and real estate workflows. ZestyAI is especially relevant to insurance-oriented buyers seeking property intelligence and risk assessment built from imagery and other data. Selection between these providers should turn on hazard coverage, geographic performance, property attributes, delivery rights and validation against the buyer’s own claims or asset history.
Measurabl and Deepki compete from a different direction. They emphasize ESG data management, emissions, reporting and portfolio sustainability operations. They are stronger candidates when the primary problem is collecting building data and managing disclosure workflows. First Street is the more focused choice when the central question is physical climate exposure and its financial significance. Some large owners may reasonably use both categories, with First Street informing risk analysis and an ESG platform managing operational performance.
Autodesk Forma is another adjacent option, particularly for teams assessing sites and early design decisions rather than monitoring financial risk across an established portfolio. BestCRE’s analysis is that First Street should win when property-scale hazard modeling is the buying priority. It should not win merely because climate appears somewhere in the requirement. Buyers need to separate physical risk, carbon management, design analysis and regulatory reporting before comparing proposals.
The Bottom Line
First Street is a serious candidate for institutional CRE organizations that need repeatable property climate screening across acquisitions, lending or portfolio management. Its scale, specialized modeling and financial orientation distinguish it from general ESG reporting tools. Proceed to a pilot if physical climate exposure already affects investment policy, credit review, insurance strategy or capital planning.
Do not sign an enterprise agreement before validating representative properties across each important market and hazard. Require methodology documentation, data lineage, update procedures, service commitments and clear usage rights. BestCRE’s analysis is that First Street deserves a place on a sophisticated buyer’s shortlist, but only as a governed risk input. It is not a substitute for engineering judgment, insurance evidence or a complete sustainability operating platform.

Frequently Asked Questions
What is First Street climate risk data?
First Street provides property-oriented climate risk models intended to connect physical hazards with financial decisions. CRE investors, lenders, insurers and asset managers can use the data to screen buildings and portfolios for hazards such as flooding, wildfire and extreme heat. The product is best understood as an analytical data layer for underwriting, risk management and portfolio surveillance. It is not a property management system, carbon accounting platform or replacement for site-specific engineering. A user can apply its results to identify properties that deserve closer review, compare exposure across markets and examine concentrations within a portfolio. Because the outputs are modeled estimates, they should be interpreted alongside insurance information, local records, physical inspections and professional diligence whenever the decision has a material financial consequence.
How does First Street compare with Measurabl and Cotality?
First Street is more specialized in physical climate risk modeling than Measurabl, which focuses more broadly on real estate ESG data, emissions and reporting workflows. A CRE owner may use First Street to assess flood, wildfire or heat exposure while using Measurabl to collect utility information and manage sustainability reporting. Cotality is a closer data competitor because it serves property, mortgage and insurance workflows with extensive real estate and hazard information. The right choice depends on the required hazards, geography, property resolution, financial outputs and integration rights. BestCRE’s analysis is that First Street is strongest when future-oriented climate exposure is the primary buying problem. Buyers needing a wider property data ecosystem or operational ESG management should compare the alternatives carefully and may require more than one system.
How much does First Street cost?
First Street does not publish standard institutional prices or public subscription tiers. Buyers need a custom quote based on factors such as the number of properties, geographic coverage, hazards, delivery method, update frequency and permitted uses. Procurement teams should ask whether implementation, API consumption, bulk data delivery, additional users, model updates and support are included. They should also confirm storage, redistribution and post-termination rights because restrictions can affect integration with investment and lending workflows. Analysis: estimate value by multiplying staff hours saved through automated screening by the organization’s fully loaded labor cost, then add any verified reduction in outside screening expenses. Compare that benefit with the complete annual contract and implementation cost. Avoid justifying the purchase with hypothetical avoided losses unless the organization can support those assumptions with its own evidence.
Who should use First Street?
First Street is best suited to CRE investors, lenders, insurers and asset managers that evaluate enough properties to benefit from consistent climate screening. Typical users include acquisitions analysts comparing opportunities, credit teams reviewing collateral, portfolio managers identifying geographic concentrations, insurance teams investigating exposure and sustainability leaders incorporating physical risk into governance. The best customers have reliable property identifiers, a central data environment and defined escalation rules for high-risk results. They can connect a finding with additional engineering, insurance review, loan conditions or resilience planning. Smaller owners may still benefit, but a custom enterprise contract can be difficult to justify for occasional use. BestCRE’s analysis is that the product delivers the most value when climate results affect recurring financial decisions rather than appearing only in annual reporting.
What will the MSCI acquisition mean for First Street customers?
The announced MSCI acquisition could give First Street broader distribution, additional institutional reach and closer alignment with financial risk and portfolio analytics. It may also create opportunities to connect property climate information with other datasets used by investors and lenders. Those outcomes are prospective, and customers should not assume that product packaging, methodology, pricing or integrations will automatically improve. Existing and prospective buyers should ask how contracts, support contacts, data rights, product roadmaps and model governance will be handled after the transaction. They should also monitor whether First Street remains available as a distinct offering or becomes part of broader MSCI packages. BestCRE’s analysis is that the acquisition strengthens institutional credibility, but purchasing decisions should remain grounded in current functionality, validated outputs and written contractual commitments.
