Commercial real estate lenders are underwriting a larger and more scrutinised book than ever. Trepp's CRE Debt Universe report
put outstanding US income producing commercial real estate debt at USD 5.12 trillion at the end of the second quarter of 2026. Every loan in that book needs comparable sales, rent roll checks, environmental screening, credit modelling and ongoing monitoring, and most lenders now run that work through software rather than spreadsheets.
This guide profiles ten due diligence and underwriting platforms that CRE lenders use most, from market data and credit models to environmental screening, AI underwriting and construction draw management. It is grouped by what each platform does in the credit process, not ranked, because most lenders combine several of them.
What CRE Lenders Actually Check
Whatever the platform, a CRE credit file comes down to four questions. Software speeds up the answers, but it does not change the questions.
Is the value real?
Sale and lease comparables, cap rates, appraisal review and market rent support. Lenders test the sponsor's numbers against independent market data.
Does the property cash flow?
Rent roll and operating statement analysis, tenant credit, lease rollover and stressed debt service coverage. This is where most loans are won or lost.
Is the collateral clean?
Environmental history, flood and climate risk, zoning, title and physical condition. A Phase I environmental site assessment is standard for most commercial loans.
Will the loan perform?
Probability of default and loss models, covenant tracking and early warning monitoring after close, increasingly required for CECL reserving and regulator reporting.
Market Data and Credit Analytics
These four platforms supply the comparables, market fundamentals and credit models that sit behind most CRE underwriting decisions in the United States and, increasingly, globally.
1. CoStar for Lenders
CoStar
is the largest commercial property information provider in the United States. Its CoStar for Lenders
product links a lender's loan portfolio directly to CoStar's property data and its COMPASS credit default model. At launch, CoStar cited 4.6 million sale comps, 10.5 million lease comps and loan screening across 6.8 million properties.
Best for.
Small and mid sized banks that want comps, market analytics, CECL support and regulator reports in one place, without building their own data infrastructure.
2. Moody's CRE and Lending Suite
Moody's Lending Suite for CRE
covers the full loan lifecycle. It uses AI to ingest rent rolls and operating statements, runs cash flow analysis, stress testing and refinance risk, generates draft credit memos, and monitors loans after close with embedded probability of default and loss given default models.
Best for.
Banks and insurers that want market data, credit risk models and climate risk data from one provider, with a workflow that runs from origination to portfolio monitoring.
3. Trepp
Trepp
is the reference source for CMBS loan performance and a widely used provider of CRE debt analytics. It tracks loan level data across securitised and bank CRE debt, publishes delinquency and maturity research, and offers portfolio surveillance and benchmarking tools for bank and non bank lenders.
Best for.
Lenders that need loan level performance comparables, refinancing risk analysis and peer benchmarking, particularly for office, retail and multifamily exposure.
4. MSCI Real Capital Analytics
MSCI
acquired Real Capital Analytics in 2021 for USD 950 million. At the time, RCA's database covered more than USD 20 trillion of commercial property transactions in over 170 countries, with profiles of more than 200,000 investors and lenders.
Best for.
Lenders working cross border or in markets outside the US, where transaction based pricing evidence and buyer and lender activity are hard to find elsewhere.
Collateral and Environmental Diligence
Environmental and property condition risk can wipe out collateral value regardless of how well the property cash flows. Lenders screen it early and order full reports before closing.
5. LightBox
LightBox
provides parcel, ownership and environmental data used across CRE due diligence, including the historical records behind Phase I environmental site assessments. In May 2025 it launched LightBox Live, which combines tax parcels, assessor records, historical aerials and Sanborn maps in one interface, with tools supporting the ASTM E1527-21 standard.
Best for.
Lenders and their environmental consultants who need fast pre screening of collateral and a consistent record set for Phase I reports.
Underwriting, Workflow and Data Platforms
These platforms automate how a lender takes in deals, models them and moves them through credit approval. They sit on top of the data sources above.
6. Blooma
Blooma
is an AI platform built specifically for CRE lenders. It automates deal intake and pre screening, extracts and validates data from sponsor documents, runs preliminary credit analysis and updates valuations and borrower metrics across the portfolio after close.
Best for.
Regional and community banks and private lenders that receive large volumes of loan requests and want to screen out weak deals before an underwriter spends time on them.
7. ARGUS (Altus Group)
ARGUS, owned by Altus Group, is the industry standard for property level cash flow modelling and valuation. In 2026 Altus sold its Canadian appraisal and development advisory businesses to Newmark to focus on valuation and analytics software, and Newmark expanded its ARGUS Intelligence agreement
to add the AI tool ARGUS Assist.
Best for.
Lenders that receive ARGUS models from sponsors and need to re run them under their own assumptions, or that underwrite complex multi tenant office, retail and industrial assets.
8. Dealpath
Dealpath
is a deal management platform used by real estate investors and debt teams. Its debt module
centralises origination pipelines, tracks screening and underwriting, and records multi stakeholder approvals from loan creation through closing.
Best for.
Debt funds and private credit lenders with several originators and an investment committee process that needs a clear audit trail.
9. Cherre
Cherre
is a real estate data management platform that connects and validates internal and third party data sources in one place. It raised a USD 30 million Series C in 2024, with Nuveen Real Estate and RXR among the participants.
Best for.
Larger lenders and investors that already license several data providers and need one clean, validated data layer for underwriting and portfolio reporting.
Construction Lending
Construction loans carry completion and cost overrun risk that standing asset tools do not address. Lenders need budget, draw and inspection control from first funding to completion.
10. Built Technologies
Built Technologies
manages budgets, draws, inspections and payments for construction and real estate finance. In March 2026 it said its platform handles more than USD 350 billion of real estate and construction activity a year, used by more than 625 banks, private credit lenders, owners and contractors.
Best for.
Banks and private lenders with construction books that need disciplined draw control and lien waiver tracking, which is where most construction loan losses begin.

Software supports the credit decision, it does not replace third party reports.
Platform comps and environmental screens are not a substitute for an independent appraisal, a Phase I environmental site assessment, a property condition report and title review. Regulated lenders remain responsible for appraisal and evaluation requirements, and a borrower presenting only software outputs should expect the lender to order its own reports.
How to Choose a Due Diligence Stack
Start with the loan book, not the feature list.
A community bank lending on multifamily and owner occupied property needs different tools from a debt fund writing transitional bridge loans or a lender with a large construction book.
Cover all four questions.
Most lenders combine one market data source, one environmental and parcel source, one underwriting or workflow tool, and a monitoring layer. Gaps usually appear in post close monitoring.
Check integration and data rights.
Confirm the platforms connect to your loan origination system and core, and that licence terms let you store and reuse data in credit files and regulator reporting.
Test with live deals.
Run three or four recent loans through any shortlisted platform and compare the output against what your team concluded manually.
For borrowers, the lesson is the reverse. Lenders using these tools will find inconsistencies in a rent roll or a sponsor model within minutes. A clean, consistent file is the fastest route to a term sheet, and our guide to lender matching platforms for CRE deals
covers how sponsors reach those lenders.

Frequently Asked Questions
What software do commercial real estate lenders use for due diligence?
Most lenders combine a market data and credit analytics provider such as CoStar, Moody's, Trepp or MSCI Real Capital Analytics, an environmental and parcel data source such as LightBox, and an underwriting or workflow tool such as Blooma, ARGUS or Dealpath. Construction lenders often add Built Technologies for draw management.
Can AI replace a CRE underwriter?
No. AI platforms extract data from documents, flag inconsistencies and run preliminary analysis much faster than a person, but credit decisions, sponsor assessment and structuring still sit with underwriters and credit committees.
Is a Phase I environmental site assessment still required if the lender uses screening software?
For most commercial loans, yes. Screening tools help a lender decide whether a full report is needed and what to look for, but a Phase I ESA prepared by a qualified environmental professional remains the standard for most commercial lending.
How large is the US commercial real estate debt market?
Trepp's CRE Debt Universe report estimated outstanding US income producing commercial real estate debt at USD 5.12 trillion at the end of the second quarter of 2026.
