How investors should evaluate a rental property before making an offer

Question

Before you fall in love with a rental property's price, run it through the same filters every time. Here's the evaluation framework I use with my investor buyers — it works in any market.

Start with the income — verify it. Don't take the listed rent at face value. Check what comparable units nearby actually lease for, how long they sit vacant, and whether the current rent is real or aspirational. A property "renting" at $1,500 when the neighbors get $1,200 is a pricing fantasy, not cash flow.

Then stress-test the expenses. Taxes, insurance, maintenance, vacancy, and management — underwrite the deal as if you're paying for management even if you plan to self-manage, because someday you probably will. The investors who skip vacancy and maintenance reserves aren't buying cash flow; they're buying a surprise.

Know your comps cold. The purchase price has to hold up against recently sold properties with similar beds, baths, square footage, and condition. Buy on the numbers as they are, not on hope — your purchase price is the one figure you control completely, and it's where the deal is made or lost.

Finally, inspect the major systems before you commit: roof, HVAC, plumbing, electrical, foundation. Cosmetics are easy to price; systems are where the five-figure surprises live. If the numbers only work when nothing goes wrong, the numbers don't work.

Run every deal through the same checklist and you'll pass on more deals — and lose money on far fewer of them.

What's the one deal-killer you always check before making an offer — the numbers, the major systems, or the tenant situation?

Ametria, mine is the inspection — before the offer, not after.

At 236 doors in Memphis, heavy Section 8, I evaluate a house by asking one question first: what here fails a housing-authority inspection on day one? Peeling paint, missing detectors, no handrail, slow drains, a tired water heater. None of those scare me as repair costs. What they change is the calendar.

A deal can survive a soft appraisal. It cannot survive a dead calendar. Every failed inspection and every extra week of turnover is pure cost with no rent against it, and turnover plus vacancy outrun almost every repair bill we see.

So the rule is simple: if the house cannot be rent-ready inside our 21-day schedule, the price has to reflect that — or we pass.

Few investors check out the pics of comparable rentals to adjust for exterior & interior condition!

You're unlikely to get the same rent for a recently renovated property compared to a "tired" one.

Good list. Two things I'd add that catch a lot of people.

Taxes after the sale. Don't use what the current owner pays. In a lot of areas the assessment resets or jumps after a sale, and I've seen a deal that cash flowed $300 a month go to breakeven just from that. Call the assessor or look up what similar recently sold homes are paying.

Insurance quote before the offer, not after. Get an actual landlord policy quote on that address. Older roofs, old wiring, or being near a flood zone can double it, and that shows up way too late if you wait for the inspection period.

And I always ask for the actual leases plus a few months of bank deposits if it's occupied. The rent roll says what the tenant is supposed to pay, the deposits say what they actually pay.

@Ametria Chaney solid list. I'd add one: go looking for the buried capex before you're locked in. That's the stuff that ruins your day after closing. Sewer scopes and septic inspections are, hands down, the ones I'd never skip, because missing a problem there can burn you big time. Trust but verify. And I'd underwrite on what the current leases actually say, not on market rent the seller hopes for. Just my experience, but hopefully it gives you something to consider.

Ametria, my deal-killer is the cash left in the deal. That number decides whether the rest of the analysis matters. Add up the total cash in, including closing costs, rehab, and reserves. Then compare the return on that cash after all costs with what the same amount would earn in an index fund. If the deal can’t beat that by enough to cover the extra risk, it’s a pass, even when the rent and systems look fine.

James’s exit check fits with this. A deal that only returns your cash if the refinance works has a second bet built in. I’d run two versions: the return on cash if the appraisal comes in where you expect, and the return if it comes in 10% lower. If the second version still makes sense, the deal is much safer.

Ametria, for me it is the numbers — specifically the exit, checked before anything else. My buy box is narrow on purpose: Memphis single-family under $100K, and the house has to appraise at $180K to $265K on sold comps only after a standard $40K rehab. If that ARV is not there, nothing downstream works, because the refinance at 70 to 80 percent LTV is what returns the capital. Second check is rent: the 1 percent rule against real Section 8 rents, $1,395 to $1,950 for 3BR and up. Systems matter, but my rehab scope already assumes roof and HVAC money. A pretty house that fails the exit math is the deal-killer I never negotiate with.
