The mortgage insurance never came off when I moved out, which ate the deal
First house, 3 bed ranch from the seventies in a mid-priced suburb, $268k, 3.5 percent down on an FHA loan, so $9,380 down and about $7,000 in closing costs. Full payment was $2,140 a month, and $205 of that was the monthly mortgage insurance premium.
My plan was the standard one. Live there a year, move out, rent it, buy the next one. The part I got wrong was assuming the insurance would drop off once I had 20 percent equity, the way I'd read about on other loans. That's not how my loan worked, and my loan officer told me so only when I called at month 13 asking how to get rid of it. Dropping it meant refinancing, and by then I'd already moved, so any refinance would price as a non-owner-occupied loan. The quote came back roughly a point higher than what I had plus about $4,600 in costs. My payment would have gone up.
So I rented it at $2,175, which is $35 over the payment and well under water once you set anything aside for repairs. I held it seven months at about negative $180 a month in real terms, ate one vacancy month at turnover, and then sold in the spring at $279k. After commission, concessions and a small repair credit I cleared a little over my original down payment. Adding the negative months, the turn, and the moving costs, I'm out about $9,800 on a house that appreciated $11k.
What I'd do differently: underwrite the payment I'd be stuck with permanently, insurance included, and ask the lender in writing before I sign which product lets that insurance come off and what has to be true for it to come off. I underwrote the payment I had in year one and assumed year two would be cheaper.
