The file on my first live-in flip borrower taught me more than the loan
I look at deals from the lending side and I'd never seen one of these come across as a borrower profile until this spring. Someone came to me for a second position loan of 60k against a house they were 14 months into living in and renovating. I ended up funding it and it paid off on the sale, but the underwriting was different enough from anything else I look at that I want to put the structure down.
What the file looked like. House bought at 296k, comps supporting 445 to 465 finished, about 52k of work already in and roughly 40k left. First mortgage balance 271k. So on a 60k second I was sitting at 331k against an as-is value the appraiser put at 372k, and a finished value I had no way to enforce.
Three things I had to think about that don't come up on rental or flip paper.
First, exit certainty was better than a normal flip and worse at the same time. Better because the borrower had a tax reason to sell in a defined window, which is a stronger motive than a flipper's, and a flipper's motive is already strong. Worse because the earliest date they'd sell was set by the residency requirement and not by when the house was done. If the work finished at month 18 I had six months of nothing happening and no way to accelerate it.
Second, the collateral is somebody's house. Foreclosure on an occupied primary residence is a different process from taking back a vacant flip, and the timelines and protections vary considerably by state. That's a real difference in loss severity and I priced for it.
Third, the borrower's repayment source was a sale, and the tax treatment of that sale wasn't mine to verify. I underwrote it as though the gain were fully taxable, because whether the exclusion applies to a given seller is between them and their CPA, and I'm not going to hold a note whose repayment math depends on my reading of someone else's tax position.
What nearly broke it: the borrower wanted an 18-month term. That would have matured before their qualifying sale date. I wrote 30 months with a rate step at 24. They paid off at month 26.
What I'd keep: sizing the term off the earliest qualifying sale date plus a real cushion, not off the construction schedule.
