Walked away in due diligence and it still cost me $18,400
I want the boring thing that works, and a conversion is not that, but a small one came across my desk and I looked at it seriously for about ten weeks. Single story former bank branch, 4,400 sf, drive-through canopy, in a first-ring suburb. Asking $295k. Idea was three units plus keeping the vault as a weird storage amenity, which everyone I mentioned it to loved, which should have been a warning.
I did not buy it. I killed it in week ten because the sewer lateral was 4 inch and the city wanted 6 inch for three dwelling units, and the connection ran under the drive-through pavement and out to a main across a county road. The utility contractor's number for that was $61k to $80k with a bore, and the county road permit was its own timeline nobody could give me.
So I walked. Correct decision, I think. Here is what walking cost:
Earnest money, $5,000, of which I got $2,500 back because my contingency had lapsed by three days on the extension and the seller was not feeling generous. Architect for a feasibility set and code review, $7,400. Utility contractor site visit and camera scope, $2,200. Phase one environmental, $2,900, which I ordered because it's a bank with a canopy and I wanted to know about the old fuel tank rumor (there was no tank). Survey, $1,600. Plus about $1,800 in fees and mileage and a title search I asked for early.
$18,400 to learn no. On a deal I never owned.
I'm not sorry I spent it. I'd have spent $61k on a sewer otherwise, and that number would have arrived after closing. What I'd do differently is order the utility scope in week one instead of week six. It was the cheapest test at $2,200 and it was the one that killed the deal. I ran the architect first because that felt like the real work, and the architect's set assumed the plumbing connection worked. And I'd watch my contingency dates like a hawk, because three days cost me $2,500.
