There are two ways to sell a house that needs work. Fix it first and list it, or sell it as it stands. The second is what most people arriving here can actually do, and the arithmetic behind it is worth understanding before anyone quotes you a number.
Why listing as it stands costs more than the repairs would
A buyer looking at a house with a failed roof is not subtracting the roof price. They are subtracting the roof price, plus the hassle, plus a margin for whatever else is behind it. That gap is why an as is listing usually gives up more than the work would have cost.
Financing narrows the buyer pool further. Lenders care about the condition of the collateral, and a house with active leaks, missing systems or structural movement can fall out of an appraisal or fail a lender condition review, which leaves buyers who do not need financing, and investors.
Foundation movement in this part of Texas
Clay soil moves with moisture, so a house here that has never moved at all is the exception rather than the rule. Sticking doors and hairline cracks are common and are not the same as structural failure.
What matters to a buyer is whether it has been repaired, whether there is a transferable warranty, and whether anything is moving now. Saying you are not sure is a legitimate answer and it does not count against you.
Roofs, heating and cooling, plumbing and electrical
These four are what an inspection always finds and what a lender always asks about. Age alone is not a problem. Active failure is.
An older electrical panel that works is a different thing from one that trips, and we ask those as different questions, because they are different numbers.
How the repair estimate comes off your number
Your answers about condition produce a line for each item, each with the reason it is there, and the total comes off the after repair value. Every line is shown to you rather than summarised.
The estimate is also graded by the area, because finishing a house to the standard of its own street costs more in some neighbourhoods than others.
Telling us the worst of it helps you
A number that moves after an inspection is the thing sellers hate most about this business, and the way to prevent it is to say what is wrong at the start.
If the house matches what you told us, the number stands. If something material was never mentioned, we send the documented repair cost in writing and you choose: take that off, or walk away with your earnest money back.
