With rising prices and interest rates I have been able to overcome that requirement by putting more money down. 

Cash flow should not be your only consideration.

friends who moved into Dormont so that seems to be an area on the rise.  

That said, I do this with a a few investors on rentals since I'm a Realtor and Property Manager where I am boots on the ground for purchase, rehab and lease-up, however we had a strong professional experience/life together before partnering.Lending will also be a consideration as most lenders are hesitant to lend to non-citizens given the foreclosure challenges it can pose.

The main downside is being dependent on the HOA—issues like poor management, rising fees, or unexpected assessments can hurt your investment.

As you start you will want to take into consideration that many owners and hosts use more than just AirBNb to host their properties.  

DSCR recently came popular in the loan brokerage and private credit space with the rise of STRs and MTRs.Your local bank lenders will have the best rates typically.  

The main reason I decided to sell rather than hold was the rising interest rates.

My guess solely looking at your numbers is that it's an older/distressed property which means you have to account for more costs in capex. 2nd thought being it's not in the best of neighborhood then you'd have to take into consideration lower quality tenants/ neighbors and maybe increase expected vacancy and late payments.

Inventory has definintley been on the rise!
