If the rental income doesn’t sufficiently cover the debt payments by their standards, they’ll limit the loan amount, even if the property is worth more.You could try a few alternatives:•Look for lenders who specialize in commercial real estate and have more flexible DSCR requirements.

I have not done one in ages, but they are a great alternative when it comes to liquidate SFRs and you have an open time frame.

Alternative rent models (STR, MTR, rent by room, etc.) do not necessarily do better and are more work.  

An alternative could be putting all your properties under one LLC to start, then reassessing as your portfolio grows.

Alternatively you may decide not to address the capex but be prepared to deal with high frequency maintenance requests with duct tape repairs. 

The other alternative is to raise capital and be more of a fee developer, at least at the start.

Alternatively, do you think it might be better to use the 200k to make down payments on higher-quality homes, i.e., ones that are almost rent-ready, and finance the remainder of those purchases with DSCR, etc.?
