Banks look at that debt very differently than debt (mortgages) on real, appreciating assets: houses, apartments, commercial buildings, etc...And, if you're renting them out, they count a chunk of the rental income towards your overall income when calculating your credit worthiness. 

I've used a combination of private lending and traditional lending based on my personal credit worthiness.

Since its asset based financing, your credit worthiness matters to much lesser extent than when getting traditional financing.

We don't know enough about your specific creditworthiness to really say where you would land or if obtaining long-term financing is on the table, but typically buy & holder, non-bank, lenders like to see a fico of 600 and above (some want 650 and up), the property to have a DSCR of 1.25x, minimum loan amount of $75-$100k (depending on the lender), and you can't have any foreclosure/bankruptcies in the last 2-6 years (depending on the lender).

Depending on your property and your income/credit worthiness together, you can find:a) FHA loan (a conforming loan that is insured by the federal government; this insurance protects the lender in case you default.)

So factor a reasonable interest rate into your numbers.Second, any owner financing is typically based on the owner's evaluation of the buyer's creditworthiness.
