Fannie Mae guidelines do allow them to provide 12 months of cancelled checks to show that they've paid the mortgage for you and, therefore, they can remove it from your DTI, but the lender needs to sign off.

If so, in order to restore your eligibility if you don't have enough left over to buy the next property, you would need to refinance the 1st property into another type of loan. i.e. a conventional loan or Fannie Mae / Freddie Mac type of loan.

Fannie Mae just approved allowing lenders to count potential LTR rent on ADUs, for instance.They still don't like MTRs or STRs/Airbnb.

According to the Fannie Mae Home Price Expectations Survey - comprised of 100 experts across the housing and mortgage industry and academia - rates should settle at 5.7%.

Most of my properties were found on foreclosure websites, HUD, Fannie Mae, etc.

Check out HUDHomestore, Fannie Mae Homepath.com etc, get in with some wholesalers.

Was debating going the Airbnb route but it’s starting to make less sense with the new Fannie Mae rules so looking at getting into cash flowing rental properties.

With Fannie Mae's new 12 month cash-out refinance guidelines, DSCR allows you to cash out in 6 months or sooner on a BRRRR. 

FHA is a great options and you only need 3.5% down but there is also Fannie Mae 5% which can save you a little more money.When you purchase a 2-4 unit as a primary you can also use the other rents/doors to qualify.

Have you looked into Fannie Mae loans?
