When talking to lender(s) see if you can get approved for an owner occupied loan that provides you with renovation $, like a 203K loan.

What is the best approach for making offers on Assumable Loans?  

They get better over time, the longer you own it (debt costs hopefully stays same, rent stays up with inflation, appreciation, depreciation, loan pay down mostly from tenant, & is a little mini savings account).

If you're able to, house hacking is one of the best ways to start, getting a loan in your name so you get the lower interest rate, live in the property, and rent out the extra rooms.

Unless you’re your strategy is using the BRRRR system, DSCR loans don’t make unless you are maxed on residential loans. 

No credit score loans are possible, but as you noted, the rates are not nearly as good. 

@Erik Breunig  What was problematic with the loan terms?
