A buy box is a written definition of the deal you will buy. Its job is to let you say no in three seconds. Without one you'll spend every week analyzing houses no investor in your market wants.
The seven fields
- Market — one to three counties, named. Not "the Midwest."
- Price range — the *purchase* price you'd pay, not the ARV.
- ARV range — the resale band your buyers actually operate in.
- Property type — SFR, 2–4 unit, or both. Manufactured/mobile: yes or no (usually no).
- Beds/baths minimum — 3/1 is the floor in most markets; 2/1 is a rental-only product.
- Condition tolerance — cosmetic only, heavy but standing, or anything including gut.
- Exit buyer — flipper, landlord/BRRRR, Section 8, or owner-occupant retail.
Write it as one sentence
"3/1 and larger single-family in Shelby and Tipton County TN, purchase $40k–$110k, ARV $110k–$210k, any condition short of structural, sold to landlords and small flippers."
Tape it to your monitor. Every lead either matches or doesn't.
The field beginners get wrong
Exit buyer. Everything else derives from it.
- Flipper buyers need 70% of ARV minus repairs, want cosmetically-driven rehabs in neighborhoods with retail demand, and care about resale comps.
- Landlord buyers need rent-to-price ratios, care about the school zone only insofar as it affects tenant quality, and will pay 75–80% because they're not reselling.
- Section 8 buyers care about passing inspection and the local FMR schedule, and will buy in areas flippers avoid.
A house that's a terrible flip is often an excellent rental. If your buy box doesn't name the buyer, you'll price every deal wrong half the time.
Build it from your buyers, not from theory
Call ten local cash buyers and ask one question: *"What's your buy box?"* Write down all ten. The overlap is your buy box. This takes an afternoon and it's more valuable than any course.
If eight of ten say "3/2, under $130k, north side, needs cosmetic" — that's what you go find. Full stop.
What a buy box is not
- It is not a wish list. "$50,000 house worth $300,000" is a fantasy, not a filter.
- It is not permanent. Revisit it every 90 days as your buyers' appetites shift with rates.
- It is not one per market. If you work two counties with different price bands, write two.
Using it
Every lead gets checked against the box in this order — the cheapest disqualifiers first:
- County ✓/✗
- Property type ✓/✗
- Bed count ✓/✗
- ARV band ✓/✗
- Estimated purchase price ≤ MAO ✓/✗
Four of those five are answerable from a data record before you ever dial. That's the whole point: your calling hours should be spent only on properties that already survived the filter.
The compounding effect
A tight buy box makes everything downstream easier. Your comps get faster because you're valuing the same product repeatedly. Your repair estimates get more accurate because you're seeing the same era of construction. Your buyers start calling *you*, because they know exactly what you bring. Specialization is the whole game.
