Modeling the refinance at last year's rate cost me 31k of trapped capital
Finished this one nine months ago and I've been chewing on it since.
Single family, purchase 158k, rehab came in at 41k against a 36k budget, closing and holding 11k. All in 210k. Appraised at 268k, which was honestly a good appraisal, only 7k under my estimate.
The failure was upstream of all of it. I built the model with a refinance rate I'd been quoted eleven months earlier on a different property and never re-quoted before going firm. By the time I got to the refi the rate was meaningfully higher, and the problem wasn't the rate itself. It was that the lender sized the loan to the property's debt service coverage, not to the loan-to-value ceiling I'd planned around.
At 75 percent of 268k I'd have gotten 201k. Rent is 2,100. Taxes and insurance 610 a month. At the actual rate, the payment on 201k plus taxes and insurance put coverage below their 1.15 minimum, so they sized me to 170k instead. That's 31k of mine still in the house that I'd already mentally allocated to the next purchase.
So the constraint that bound wasn't the one I underwrote. I spent six weeks worrying about the appraisal and the appraisal was fine.
What I'd do differently: model both the value ceiling and the coverage ceiling on every deal, take the lower, and re-quote rates before going firm rather than before starting the search. And stop pre-spending the cash-out. The next deal I'd lined up went to someone else and I don't get that back.
