Quote from @Janet Behm: Victor,How wonderfully generous of you!

I still need to link up with a contractor and talk this out, but I'm wondering if anyone had examples where they put around $50k into a home and what the results were. 

If you're looking for insights or need financing options for flips or rentals, I'd be happy to help.

The planning staff should be able to walk you through any options for zoning changes or variances if there's a way to make short-term rentals work in your case.

Your suggestion to list on open market likely is the best option for the OP.  

I have saved up some money but my goal is to save up at least 20k in a year before I start looking for options on house hacking in a duplex.

If this was true we would all be buying options, swaps, and other derivatives.

I just received two different verbal offers that I'm willing to accept, but don't want to waste time with someone whose deal may fall through.What are my options to enter into a contract with someone who is qualified?

Wondering about investing and then filling the park up to get to full occupancy. 

I do agree with @Jules Aton though, the best option may be to wait and save up for your down payment.
