Took a 60k discount on a 4-unit, gave back 71k finding out why
Closed this last spring, done unwinding it now, so here are the numbers.
Off-market lead, tired landlord, 22 years of ownership, came off a mail campaign I'd been running for six months. Four units, two 2/1s and two 1/1s, brick, decent bones. He gave me a rent roll showing 4,150 a month collected and said comparable buildings were trading around 470k. I bought at 412k, 25 percent down, small local lender. I thought I had a 58k discount for being the only person he talked to.
What the rent roll actually was: a list of lease amounts. Not deposits. One tenant had been paying 600 of an 950 rent since the previous fall and the seller had been letting it slide because he didn't want the fight. Another had stopped paying entirely in February and the seller described that unit as occupied. Real collected rent in my first full month was 3,050.
What it cost me, itemized. Eviction and legal on the non-paying unit, 3,900, and it took eleven weeks in my county. Turn on that unit after they left, 14,200, including a floor I didn't expect. The 600 tenant negotiated up to 800 and then left anyway, another 6,800 turn plus six weeks vacant. Sewer lateral that backed up in month two, 9,400. Roof section, 7,500. Carrying the shortfall against a 2,190 payment for most of eight months, roughly 12,000 out of pocket. Plus a 4,000 assessment I hadn't caught for a shared alley agreement. That's about 58k of hard cost, and I'm calling it 71k with the eight months of my own labor and the interest I paid on a HELOC I drew to cover it.
The building is stable now at 3,900 collected and it will be fine in five years. The discount is gone.
Where it went wrong was one step, and it wasn't the walkthrough. I priced the purchase off the seller's stated rent roll and never asked for the bank statements that would have shown me 3,050. He wasn't lying to me. He genuinely thought of those as his rents. I had estoppel certificates in my checklist and skipped them because the seller was friendly and I was worried about being the buyer who asks for too much.
What I'd do differently: no off-market residential purchase over two units without twelve months of deposits from the actual account and a signed estoppel from every tenant, before I set a price rather than during inspection. And I'd treat "the owner is tired" as information about how the building has been run, not as a reason the price is good.
