Adults pick houses, and typically women, so if you can appeal to them, you will do well. 

Welcome to adulting.

Some millionaire dude whose assets were frozen by the court did adopt his adult GF to successfully cheat the system and gain access to his funds- Have your SO and the other roommates not pay you and then claim the business losses- Allow the house to be burned for a casualty loss on taxes and an insurance claimThat's all the advice I can give you for free. 

Keep living with your relatives, this is an exceptional financial opportunity that you may not have again (or want again) as an adult.

More adults living in Vegas were born in California than Nevada.

Firstly, you should realize that you do have control of the situation, you just need to let the tenant know that ASAP.We all know that moving can be stressful, but it does not release an adult from their responsibility to comply to the lease terms they agreed upon.  

And I'm worried my community will suffer because my local schools, police departments, fire departments, social services, road repair crews, graffiti abatement crews (this is LA, after all), adult education programs, job placement programs, etc., will receive less funding.So this tax abates my fears.

One family member still living in the house with two adult children.

The property seems to be in a higher crime rate area (stealing, a couple shootings) and my parents and the adults around me are telling me to back out.

I'm hoping to acquire 10 BRRRR houses that are $500k ARV, which I expect will all be worth $750k after 30 years, for a total holding of $7.5M at the end of 30 years, which the kids can sell and retire off of.Mike,Care to adopt an adult?
