If you can rehab your way into a house-hack of a small multifamily and live on site, I think that would allow you to improve your cash flow by getting a short-term rental license even though the city is making it harder to do STRs.

More specifically can you get utilities to the site?

I do occasionally post about it on some of the social media sites for travel nurses, such as Travel Nurse Gypsy Housing for example. 

It is a lofty goal with no easy path to accomplishment, but what you describe seems unlikely to accomplish the goal.Note most people on this site are RE investors.

Quote from @Hector Espinosa: Hi,I'm negotiating a seller financing deal which may be my first one and would like to ask for some advise about and what are advantages and disadvantages about seller financing deals.These are the seller financing terms:House Price: $330,000.00 USD​ (Sellers still owe ~$301,000 USD)Down Payment: 5% = $16,500 USD​Loan Amount: $313, 500​ (Monthly payments will be amortized as a 30 years loan​)Interest Rate: 4.531%Balloon Loan Term: 5 YearsMonthly Payment (P&I): $1,594.24​Closing Costs:  ~$3300 ​Zip Code: 74105Observations:       * HVAC requires an update but pending to inspection (replacing with a new one will cost ~$10,000 - $15,000 USD )     * Expected Rent Income: $2,000- $2,300 but this is has been really complicated to get a good estimate because is all over the place in the different sites I have checked

Since you mentioned a construction site injury in your initial post, the best way to proactively avoid premises liability claims is by keeping a clean worksite.

The primary form of diligence we see on the forums is "what do you think of XYZ sponsor and deal" whereas the common form of diligence in the space by institutional investors, large investment groups, family offices, and sophisticated investors involves following the sponsor for years, underwriting the deals, validating rent comps, background checks on the general partners, and a host of other diligence that materially de-risks the investments.
