An automated valuation model (AVM) is a statistical model that estimates a property's value from data, with no appraiser involved. For commercial real estate it is usually a screening tool: fast and cheap to call, but weak on the income and lease details that decide what a commercial property is worth.
How a commercial AVM works
Most models combine three things:
- Sales of similar properties, adjusted for size, age, location and date.
- Property facts: area, year built, use, assessed value.
- Market trends, such as price movement for the property type in the area.
Some also use income, but only if the data is there. For many commercial properties it is not, which is the main reason the output is wide.
A worked example (hypothetical numbers)
A model values an 18,000 sq ft retail building from three nearby sales at 270, 310 and 355 per square foot. The median is 310, so the estimate is 5,580,000. The three sales alone support anything from 4,860,000 to 6,390,000.
That spread is 27% of the median. A single figure of 5,580,000 hides it. A value opinion that lists the three sales, the adjustments and the range lets the reader judge which comparable is closest. The properties and prices here are invented to show the arithmetic.
When an AVM is enough, and when it is not
- Enough: a first look at a portfolio, ranking addresses to review, or a check on a number someone gave you.
- Not enough: pricing a purchase, setting a loan amount, or anything a lender, auditor or court will rely on.
What an AVM does not replace
It does not replace a licensed appraisal, and Titleman's output does not either. Titleman returns a value opinion, which shows its comparables and sources and gives a range. It does not give a final price. For the cost and timing of an appraisal, see how much a commercial appraisal costs.

Common questions
Is an AVM an appraisal? No. An appraisal is a signed opinion from a licensed appraiser. An automated valuation model is a computer estimate with no signature. Lenders may use one for screening or monitoring, but a loan on a commercial property normally still rests on an appraisal.
Why are AVMs less reliable for commercial property than for houses? Houses are alike and sell often, so models learn from thousands of near copies. Commercial properties differ in tenants, lease terms and income, and few sell in any one market, so a model has little to compare against.
What does an AVM need to work? At least the address, size and property type. Better models also use the income, the leases and the sales of similar properties. The thinner the inputs, the wider the real uncertainty, whatever single number comes back.
What does Titleman return instead of an AVM figure? A value opinion. It shows the comparables, the method and the sources, and gives a range, so you can see why the number is where it is. Titleman measured a median of about 45 minutes for a value opinion run over the 30 days to 18 October 2026.
