The appraisal comes back and the value is fine. Buried in the comments is one sentence: stepped cracking observed in the foundation wall at the northeast corner, recommend evaluation by a qualified structural engineer. Twelve words, and your file just stopped.
Most investors read that as a repair condition and start getting bids. It is not a repair condition. It is an evaluation condition, and the difference controls everything that happens next: who you hire, what the document has to say, how long it takes, and whether the lender can escrow around it at all.
Evaluation is not repair, and that distinction is the whole thing
When an appraiser writes a report subject to repairs, the problem is known and the cost is knowable. A missing handrail, a broken window, a section of gutter. Somebody fixes it, somebody reinspects, the file moves. That is a well worn path and lenders have a structure for it.
A structural note is different because the appraiser is not qualified to tell you how bad it is. An appraiser is trained to value property, not to diagnose foundations, and the professional standard when they see something outside their competence is to flag it and hand it off. So the condition is not “fix this.” It is “nobody in this file knows whether this is a thirty year old settlement crack that stopped moving in 1998 or an active failure that needs forty thousand dollars of underpinning, and until somebody qualified says which, we cannot lend against it.”
That is also why the condition rating on the appraisal is often unaffected. A house can carry a C3 condition rating and still generate a structural referral, because condition ratings describe finish and maintenance, not structure. Investors see a decent condition rating and assume the structural note is minor. It is a separate axis.
Who has to write it, and who cannot
The letter has to come from a licensed professional engineer, usually a structural PE, stamped and signed. Three substitutes get offered constantly and all three get rejected.
A home inspector’s report. General inspectors are explicitly not structural engineers and their own reports say so, usually in the same sentence recommending an engineer. Useful for you, worthless to the underwriter.
A foundation contractor’s free evaluation. This is the one investors fight about, and the lender’s position is correct. The contractor who inspects for free is selling the repair. Their assessment and their bid are the same document and the incentive is obvious. Some lenders will accept a contractor bid as the cost basis for an escrow, but only after an independent engineer has already established that a repair is needed.
The seller’s old engineer letter. Sometimes genuinely useful, usually not. If the seller has a letter from 2019 saying the condition was stable, that is evidence the movement is historic, which is the single most helpful fact available. But most lenders want a current evaluation, because stable in 2019 does not establish stable today.
Expect to pay somewhere between five hundred and twelve hundred dollars, and expect to pay it yourself. On a purchase, the buyer pays for lender required reports. It is not refundable and it does not credit back.
The three findings the letter has to contain
This is the part worth knowing before you hire anybody, because a letter that omits one of these gets sent back and you lose another week.
Whether the condition is structural. A plain statement that the observed cracking is or is not affecting the structural integrity of the building. Engineers hedge by training, and a letter full of qualifications satisfies nobody. Tell the engineer up front that a lender is the audience and that the letter needs a conclusion.
Whether the movement is active or stable. This is the finding that decides the outcome. Historic settlement that has stopped is usually clearable with no repair at all. Active movement is not, and no amount of cosmetic patching changes that.
If repair is needed, the scope and an opinion of cost. The lender needs a number to size an escrow. An engineer who specifies a scope without a cost forces a second round of contractor bids, which is another two weeks.
Many lenders also want a statement that the property is safe and habitable in its current condition, because that is the question the servicer cares about if the loan funds before any repair happens.
The three outcomes
Cleared with no repair. The most common outcome by a wide margin. Most residential foundation cracking is historic settlement, and an engineer who finds no active movement writes a letter saying so. The underwriter clears the condition and the file resumes. Elapsed time, five to twelve business days.
Repair required, escrowed. The engineer finds a defined, bounded problem with a specified fix. The lender holds back funds at closing, typically one and a quarter to one and a half times the bid, disburses on completion and reinspection. This path exists and works, but note that it requires the lender to be comfortable funding against a structure that currently has a known defect, which is a different risk posture than escrowing for a handrail.
Repair required before closing. Where the engineer finds active movement, or where the scope is large enough that the lender will not hold collateral in that condition. Now somebody has to do the work before funding, which means the seller does it, or the seller credits you and you do it after an extension, or the deal gets renegotiated.
Which of the three you get is almost entirely determined by the word active.
What it actually costs, worked through
Take a two unit rental under contract at two hundred eighty five thousand dollars. Twenty five percent down puts the loan at two hundred thirteen thousand seven hundred fifty dollars at seven and a quarter percent on a thirty year amortizing structure. Principal and interest runs about one thousand four hundred fifty eight dollars a month. Taxes are thirty nine hundred a year, or three hundred twenty five a month. Insurance is sixteen hundred a year, or one hundred thirty three a month. Total monthly obligation: one thousand nine hundred sixteen dollars.
Gross rent is twenty two hundred dollars. Coverage ratio is twenty two hundred divided by one thousand nine hundred sixteen, which is 1.15. Tight but workable.
The engineer finds active movement at the rear corner and specifies pier underpinning plus exterior drainage correction, with an opinion of cost at twenty two thousand dollars.
If the lender escrows at one and a half times, they hold thirty three thousand dollars. That is cash you bring to closing on top of your seventy one thousand two hundred fifty dollar down payment. Your cash to close goes up by roughly forty six percent, and you get it back only as the work completes.
Now the version investors do not anticipate. The appraiser, on reconsideration with the engineer’s report in hand, revises the as-is value to two hundred sixty eight thousand dollars. Your loan is sized on the lower of price or value, so it drops to two hundred one thousand dollars. Principal and interest falls to about one thousand three hundred seventy one, and your total obligation falls to one thousand eight hundred twenty nine dollars. The ratio actually improves, to twenty two hundred divided by one thousand eight hundred twenty nine, or 1.20.
Which is the counterintuitive and important point: on a structural condition the coverage ratio is almost never the binding constraint. The cash is. The lower value does not hurt your ratio, it increases your down payment by twelve thousand seven hundred fifty dollars, and that is on top of whatever escrow the lender wants. Model this on the cash side of the ledger, not the ratio side. The DSCR deal calculator will confirm the ratio holds, and how to calculate DSCR shows why a smaller loan moves it the direction it does.
The insurance problem riding behind it
An engineer’s finding does not stay inside the loan file. Carriers ask about structural conditions and prior foundation repair, and an active movement finding can produce a decline or a surcharge at exactly the moment you need a bindable quote.
This is the same shape of trap as a roof age insurance decline repricing a finished file, and it lands at the same point in the timeline, which is late. If the property is old enough that a carrier will want a four point inspection anyway, assume the structural question comes up there too, and get the insurance conversation started the same day you order the engineer.
Where these conditions come from
Five things generate a structural referral with any regularity, and knowing them lets you price the risk before the appraiser ever shows up.
Expansive clay and poor drainage. Downspouts dumping at the wall, negative grade, no gutters. Produces seasonal movement that looks alarming and often is not.
Undermined ground. In regions with historic deep mining this is its own category with its own coverage requirements, and what a lender requires on mine subsidence and sinkhole risk is a separate analysis from ordinary settlement. Do not let an engineer treat one as the other.
Old repairs done badly. Carbon fiber straps, wall anchors, or poured piers installed by a prior owner. Visible evidence of past repair almost always triggers a referral, even when the repair worked, because the appraiser can see that something happened.
Unpermitted work. A load bearing wall removed during an unpermitted remodel is the genuinely dangerous version. It also overlaps with unpermitted finished square footage, which is its own underwriting problem on top of the structural one.
Water, over decades. A chronically wet basement eventually becomes a structural question. It frequently arrives alongside other old building issues, including the supply lines you cannot see and, on properties with their own water systems, well and septic inspections with timelines nobody underwrites.
Getting ahead of it
Order the engineer during due diligence, not after the appraisal. This is the entire play. A structural report obtained in week one costs the same money and arrives when you can still walk for free. The same report obtained in week four arrives after other third party findings have already eaten your calendar, and frequently after your deposit has stopped being protected.
Walk the perimeter yourself before you offer. Stepped cracking through mortar joints, doors that do not latch, a chimney separating from the wall, floors that slope toward one corner. None of these is proof of anything, and all of them predict a referral.
Ask the seller for prior reports in writing. A twelve year old engineer letter plus a current one showing the same crack at the same width is the strongest possible evidence of stability, and it converts a two week problem into a three day one.
Do not confuse this with the repair-or-replace decision. Deciding whether to repair or replace a furnace, roof, or water heater is a capital planning question you control. A structural condition is a gate: you do not get to decide how much of it to address, the engineer and the lender do.
Two related reports that generate the same kind of late stage surprise and are worth ordering early for the same reason: a wood destroying insect report, which can itself find structural damage, and, on a property that has been sitting, the access and appraisal limitations that come with a winterized building.
One thing that is not a defect
A house that has settled and stopped is not a damaged house. Half the housing stock built before 1950 has visible settlement and most of it is structurally fine. An engineer’s letter establishing historic stable movement is a permanent asset: keep the original, because the next buyer’s appraiser will flag the same crack and you will hand them the answer.
What you are paying the engineer for is not a repair. It is a conclusion, and the conclusion is usually good news. The expensive part is getting it late rather than getting it at all. And a layout quirk that an appraiser flags is often functional obsolescence rather than structure, which is a value question and not a gate.
One last file note. If the property is tenant occupied, the engineer needs interior basement access, and arranging that runs into the same scheduling problem as everything else on an occupied rental, including the documentation issues that come up when the tenant pays in cash and the seller has no written system for reaching them. Get the tenant’s phone number in writing at contract signing. And read the title commitment while you wait, because the exceptions page occasionally shows a recorded notice related to a prior structural order.
The short version
A structural referral on an appraisal is a request for a conclusion, not an order to fix anything. Hire a licensed engineer, not an inspector and not the contractor who wants the job, and make sure the letter states whether the condition is structural, whether the movement is active, and what a repair would cost. Most of the time the answer is stable and the file clears in under two weeks. When it is not, the pain lands in your cash to close, not in your coverage ratio, because a reduced value shrinks the loan rather than the rent. Order it in due diligence and the whole problem costs eight hundred dollars and a phone call.
