Sb13 gave legal standing for safe unpermitted units for 5 years.  

Do you have heat, water, stove/oven that work, a safe unit?  

Nowhere is safe.  50 years from now short term rentals in residentially zoned areas will not exist. 

These investors are typically large financial institutions looking for safe, predictable returns, such as pension funds, insurance companies, and banks.Key concepts to understand in economics and finance are risk and reward.

@Steven Hamilton II hi Steven,Is this related to same topic or a seperate tax law to the 750 hour Real Estate Professional benefit (in my case something to consider for spouse in future) tnk you. https://www.claconnect.com/resources/articles/2019/irs-safe-harbor-on-section-199a-impacts-tax-filing-for-rental-real-estate

You don't mention how old this place is, you don't mention where this place is, but I think it's pretty safe to assume your place was once a big old single-family residence that was Mickey-Moused into a Section 8 duplex maybe fifty-sixty years ago and sits squarely in what is now a D-class neighborhood.Sell it.

I've recently came across this technique of assuming the sellers mortgage when purchasing the house.

If you want to learn more about the practice (and art) of safely and securely finding and funding a PML to see if it's for you, check out my book on BiggerPockets called Lend to Live: Earn Hassle-Free Passive Income in Real Estate with Private Money Lending. 

Also, figure out different marketing techniques including referrals.

My recommendation is to choose cities in safe and economically diversified areas with above-average income and population growth.
