It’s harder to BRRRR in the Tulsa area now due interest rates, you definitely have to buy at a great discount in order to be all in low enough toget all of your money out and the rents have to be high enough to still cash flow after all expenses (PITI, Mgmt, Vac’s, Rep/Maint, CapEx, HOAs, Util).Based on being “all in” $120K in order to BRRRR and still cash flow at least $300 mo:$120K cash out amount - at 7%/30 yr ($150K+ ARV)PI = $800 mo + Taxes $150 + Ins $150 = $1100mo PITIRENT would have to be at least $2000 mo- $1100 PITI- $200 mgmt (even if self mng, it’s exp for time)- $200 vacancies- $200 Rep/Maint & CapEx= $300 mo cash flow.

I could never buy land in brickell it's more than 300 million per acre. but in columbus I can buy an infill lot for 40-60k within 1mile of Downtown Columbus. we looked at hundreds of Floorplans and found that 2 bedrooms seemed to be better than 1 and we wanted a tight compact floorplan that could get high rents. rents are higher Downtown Columbus and property values are higher Downtown Columbus by more than 40%. after that we wanted 4 units but it was commercial so we stuck to 3 units because it's residential. in February of 2024 we submitted our first design of a stacked triplex that is 2 beds 1 bath. after design changes, we now have about 7 approved in our market. all of the underwriting of banks is based on long term rentals.

Maybe your wife would be willing to take a lump sum based on the equity in the Air BnB. 

The property is likely a little too expensive for me to qualify for with a conventional loan based on DTI.
