Real Estate Underwriting & Valuation
Lenders, investors and asset managers use ComFinData property datasets to underwrite with evidence — automated valuations, market comparables and operating benchmarks that stand up in credit committee.
Underwriting lives and dies on comparables
Every valuation is an argument from evidence: what similar assets are worth, what they earn, what they cost to run. When the evidence is thin — a stale appraisal, a broker's pro forma, three cherry-picked comps — the argument fails exactly when it matters, in credit committee or in front of an auditor.
And after closing, the evidence problem doesn't end: portfolios need collateral values and operating benchmarks that refresh, not a valuation frozen at origination.
Property evidence at portfolio scale
ComFinData's real estate catalog covers the underwriting evidence chain: residential property valuations (AVM) for origination and portfolio marks, commercial real estate listings for comparables and deal screening, and multifamily rent and operating-expense benchmarks for NOI underwriting.
Adjacent layers strengthen the file — satellite land-use data for physical risk on collateral, and environmental quality scores that increasingly move both value and regulation.
A defensible valuation workflow
Originators typically wire AVM values into pre-qualification and use benchmarks to pressure-test sponsor pro formas; asset managers refresh collateral values on a portfolio cadence and flag assets drifting from market.
Because each dataset documents its methodology surface — fields, cadence, coverage — the valuation file explains itself when a regulator or investor asks how a number was reached.

Frequently asked questions
Can valuations be refreshed across an entire loan portfolio?
Yes — AVM datasets are built for batch delivery keyed to your collateral identifiers, on monthly or quarterly cadences. That turns portfolio revaluation from an annual project into a scheduled data load.
Do the multifamily benchmarks cover my metros?
The rent and opex benchmark dataset documents its geographic coverage and line-item schema on its product page. If you underwrite in markets at the coverage edge, raise them on the discovery call — coverage scoping is part of the standard process.
