I am currently ending the co-ownership because my dad seriously screwed me over & I have no idea if it'll end with me getting half the fair market value now or waiting until my parents die before I assume it. 

A few things to keep in mind:Section 8 requires the property to pass an inspection based on HUD’s Housing Quality Standards (basically making sure it’s safe and well-maintained).The rent you charge has to align with Fair Market Rents (FMRs) in your area, so it’s good to check what similar properties are renting for.You’ll still be responsible for maintaining the property, but the upside is that a chunk of the rent is guaranteed by the government, which can provide steady income.Check with the local housing authority about any specifics for your area—every jurisdiction does things a little differently.This could be a great niche if you can find a good deal on the land and make sure your expenses (like maintenance, insurance, and occasional vacancies) are covered by the rental income.

Renewals and rent increases- Research market rates; 3% is fair, but adjust if you’re far below market.

My area generally has fairly long term renters.

I can get my GC license fairly quickly and without too much hassle from prior experience.

There's a bunch of houses out there with "in law" units that make ADU conversions simple and affordable.

All of my assumptions were based on that 2 unit residential and are fairly accurate between rental rate and ARV. 

Doing a quick search, I see a bunch of duplexes in and around Austin available in the price range you are talking about, if that's where you are from and want to live in the future.

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

The Federal Trade Consumer’s Bureau of Consumer Protection stops unfair, deceptive and fraudulent business practices by collecting reports from consumers and conducting investigations, suing companies and people that break the law, developing rules to maintain a fair marketplace, and educating consumers and businesses about their rights and responsibilities.In all other industries consumers are able to rate the performance of service providers and potential investors have a right to have these insights.
