The Appraiser Who Keeps Signing the Form

Gil Trueworth is a fictional character. His credentials, his professional bind, and his mechanical pencil are invented. The snowpack data, the fire forecasts, the insurance retreat, the FEMA cuts, and the two-inch text field on Fannie Mae Form 1004 are all real. We are not certain which parts of this interview are the fictional ones.

We met Trueworth at the subject property, a 2,400-square-foot stucco ranch in Anthem, Arizona, thirty-five miles north of downtown Phoenix. He was completing a Uniform Residential Appraisal Report for a conventional thirty-year fixed-rate mortgage. He arrived at 8:15 a.m. with a laser measuring tool, a clipboard, and a mechanical pencil he's carried since 2003. It was already 94 degrees. Across the cul-de-sac, someone's irrigation timer had kicked on at dawn and was still running, a small arc of water darkening the concrete in a pattern that shrank visibly as we watched.

The backyard of the subject property had been xeriscaped the previous fall, after the HOA quietly dropped its turf-grass requirement. The sellers are asking $485,000. The lender needs Trueworth's number by Friday.

In mortgage finance, few numbers carry more weight than the appraised value. It sets the loan-to-value ratio, determines credit risk, underpins whether the loan can be packaged, securitized, and sold to investors who will never see this cul-de-sac. Federally backed mortgages account for roughly three-quarters of outstanding single-family mortgage debt in the United States. The appraiser's signature is the hinge on which all of it turns. Trueworth has produced this number approximately seven thousand times. He is, by every professional measure, exceptionally good at it.

He is no longer sure the number means what it used to.

You've been appraising properties for nearly three decades. What's the assignment today?

Gil: Twenty-eight years. Licensed in four states: Arizona, Utah, Colorado, Nevada. MAI and SRA designated, for whatever that's worth at this particular moment. Today is standard. Single-family, fee simple, mortgage lending purposes. The lender wants to know if this property is worth what the buyer agreed to pay. I pull comparables, measure the house, assess condition, note factors affecting value in the subject's market area.

I could do this in my sleep. I have done it in my sleep. My wife says I mutter square footages.

When you pull comparable sales right now, what do you find?

Gil: Three closed sales within a mile, last six months. All three transacted with homeowner's insurance in place. All three closed with buyers who could obtain a thirty-year fixed-rate mortgage. All three happened before this snowpack season. Before the March heat event.¹ Before the fire outlook dropped last Tuesday.²

And I'm sitting here making adjustments for square footage and garage count while the thing I actually need to adjust for — whether the conditions that made those sales possible still exist — has no line item. There is no field on Form 1004 that says comparable sales may have occurred in a functionally different climate regime.

I adjust for pools. I adjust for covered patios. I do not adjust for the fact that the atmosphere changed between the comp date and the effective date.

The western snowpack numbers came out last week. Lowest on record. How does a property appraiser process that?

Gil: Not as a climate scientist. As someone filling out the Site section of a form.

Snow water equivalent across the western U.S. is 65 percent below the 1991-to-2020 normal, the lowest on record since tracking began in 1981.³ And that normal is itself warmer and drier than the previous baseline. So we're 65 percent below a number that was already below what the water infrastructure was designed for. You follow? The benchmark is wrong and we're missing it by a mile.

This property gets its water from the Central Arizona Project, which pulls from the Colorado River, which is fed by snowpack that is, as of last week, functionally not there. Glen Canyon Dam could fall below minimum power pool by December. No hydroelectric generation for customers across seven states.⁴ Denver Water just announced restrictions for the first time since 2013, citing the lowest snowpack in forty years in both collection basins.⁵

Here's the part I keep turning over. The Colorado River Compact, 1922, seven states, the foundational water-allocation agreement for the entire Southwest, promised 16.5 million acre-feet per year. The actual long-term average flow was 14.7 million. The compact was overallocated the day it was signed. The operating guidelines governing those allocations expire at the end of this year.⁶

I am standing in the backyard of a house whose value I'm certifying for a thirty-year mortgage, and the water agreement that serves it was wrong when it was written a hundred and four years ago and expires in eight months. The form has a text field in the Site section for noting adverse conditions. It is approximately two inches wide.

I haven't even mentioned the El Niño forecast. Models are pointing toward a potential Super El Niño forming this summer, persisting through winter.⁷ El Niño means drought and heat in the West. The conditions that produced this snowpack crisis become the starting point for next year's. Nobody is asking me to value a property at the end of something. They're asking me to produce a number as the next cycle begins.

And the fire outlook?

Gil: Every state in the West. Above normal.⁸ Acres burned through March already at 231 percent of the ten-year average. Earliest snowmelt on record in the Four Corners, by four to six weeks.

I note it.

How does insurance availability factor in?

Gil: Insurance isn't a factor in the appraisal. Insurance is the gate. If the buyer can't obtain homeowner's insurance, the lender won't fund the loan. No loan, no sale. No sale, no comp. No comp, no basis for my number. The whole chain just stops. You pull one thread and you're holding air.

Average premium nationally is now $2,400 a year, nearly double what it was in 2020. Fourteen percent of owner-occupied homes are uninsured, a number that jumped six points in two years. The ECB found that banks technically price climate risk but underestimate it by roughly... (he gestures vaguely) ...a lot.⁹ About forty basis points where the actual differential is far larger. The market I'm pulling comps from is systematically mispricing the risk I can see through this kitchen window.

Every comparable sale I rely on inherits that error. And my professional obligation is to use those comps anyway. That's the job. Certified mispricing, delivered by Friday.

FEMA is expected to lose up to half its workforce as fire season begins. Does that show up in a residential appraisal?

Gil: It should. The entire mortgage risk architecture, origination through securitization, assumes a federal disaster backstop. FEMA's CORE response teams, the people who actually show up after something happens, are being cut. Several thousand contracts ending this year.¹⁰ Disaster loan denial rates already exceed forty percent for lower-income applicants during major events.

When that backstop contracts, the uninsured loss doesn't disappear. It lands on the homeowner, then the lender, then the securitized pool, then the pension fund holding the tranche. But there is no comparable sale that prices in FEMA may not come. That transaction hasn't occurred yet. By the time it shows up in my comps, it will be far too late to adjust for.

You started to mention NOAA earlier, off the record. Can we go there?

Gil: (He sets the clipboard on the kitchen counter. Carefully, the way you set down something you're not sure you want to pick back up.)

My methodology depends on standardized climate data. The U.S. Climate Normals, thirty-year averages computed from over fifteen thousand precipitation stations and seventy-three hundred temperature stations, updated every decade by NCEI. Current set covers 1991 to 2020. Next update due in 2031. NOAA terminated 880 staff last year. The fiscal year 2026 budget zeroes out climate research. The labs that maintain the monitoring network, including Mauna Loa, are being targeted.

So. The instruments that would tell me whether my comparables are still valid are being switched off while the conditions they measure accelerate. I am producing a certified number using a methodology that requires data from an infrastructure that is being actively dismantled.

(Long pause.)

Twenty-eight years I've been doing this. I have taken every ethics seminar, every USPAP update, every market-conditions workshop the Appraisal Institute has ever offered. Not one of them prepared me for the possibility that the data itself would be defunded. You can't appraise in the dark. But you also can't tell the lender you're in the dark, because the form doesn't have a box for that either.

What number do you put on the form?

Gil: Four eighty-five.

(He picks the clipboard back up.)

The form requires a number. The lender requires a number. The bond market requires a number. The number requires comparables, and the comparables require a functioning market, and the market requires insurance, and the insurance requires a climate that behaves within historical parameters, and the climate requires —

And then someone will pull my appraisal as a comp for the next one.
