There must be other options, of which I don't know - any insight to the lending environment after 10 loans would be really helpful, thanks!

I’d estimate about a 100% return on my initial equity investment inclusive of remodel costs and forecasted closing cost if I sold.

This lending environment is extremely tough, my Uncle has told me about 10 years ago when he was doing 40 deals a year.

I agree with @Dawn Brenengen , who stated that there're requirements for both sides: the tenant has to pay rent and the landlord has to provide a safe living environment.

The thing to keep in mind with the due on sale clause, that almost no one ever talks about, is they are hardly ever called due because we have been in a perpetual falling interest rate environment.  

It's a civil environment with no aggression or violence.
