How a 2-4 Unit With One Bad Unit and Three Good Ones Gets Priced
A common situation in York County small multifamily: a fourplex where three units hum along — paying tenants, decent condition — and one unit is the problem. It's vacant and gutted, or occupied by a non-paying tenant, or in rough enough shape that it can't be rented as-is. That one unit shapes the price of the whole building more than its quarter-share suggests. Here's the math a buyer runs and the choice it leaves a seller.
Why one bad unit punches above its weight
You'd think one of four units is 25% of the building, so a problem there is a 25% issue. It rarely works out that clean, for a few reasons:
The income is missing now, but the expenses aren't. A vacant or non-paying unit still carries its share of taxes, insurance, and maintenance. It's a drain, not just a zero.
There's a known cost to fix it, and buyers price in costs with a margin for the unknown.
It signals risk. A buyer wonders whether the problem unit is a one-off or a sign of deferred maintenance lurking elsewhere.
So the discount a buyer applies to that one unit often reflects lost rent plus repair cost plus a risk buffer — which can exceed the unit's simple one-quarter share of value.
How a buyer actually prices it
An investor typically values the building two ways and blends them:
1. The three good units are priced on their actual income — real rents, real expenses, the cap rate the market supports.
2. The problem unit is valued at what it'll be worth once stabilized, minus the cost and time to get it there. If it needs $20,000 of work and three months to rent, the buyer subtracts that cost, plus a margin, plus the carrying cost of those months.
The sum is the offer. The better the documentation on the three good units, the more confidently the buyer can pay full value for that portion — and the more the negotiation narrows to just the one problem unit.
The seller's choice: fix it or price it in
This is the real decision. A seller with one bad unit can:
Stabilize it before selling — do the repairs, get it rented, and sell a fully-performing building at full value. This nets more if you have the capital, the time, and the appetite to do the work. The risk: you spend the money and time, and the market or your situation shifts.
Sell as-is and price it in — accept the discount on that one unit and let an investor take on the repair and lease-up. You net less on that unit, but you're out cleanly, with no capital outlay and no months of work.
There's no universally right answer; it depends on your capital, your timeline, and how much risk you want to keep versus hand off. The key is going in with eyes open about how the one unit is being valued, so the discount doesn't feel like a lowball when it's actually the math.
What helps your price either way
Whatever path you choose, two things protect your number:
Clean documentation on the three good units — leases, rent ledger, expense history. The stronger that is, the less a buyer discounts the whole building out of uncertainty.
Honesty about the bad unit. A buyer who discovers the problem unit is worse than described retrades hard. A buyer who was told the truth up front prices it once and sticks.
