The first being - don't bring your friends or family into the mix :)Since it sounds like you're pretty solidified in your friend moving in, and it could be a good first roomie, so just to get your feet wet... i'll double down on Laura's advice - do a lease, for the legalities, but i also highly recommend some sort of written (we call it a) Room Mate Agreement.

Call the sec8 case worker and tell them what your doing with the bedroom. 

If you're looking for rent estimates for MTR, there is a great tool called Pricelabs.

Which leads to other posters to offer no sympathy for those investors and then the name calling started.

Both were back when I had a proliferation of 0% balance for 18/24 & 0% transaction fee, and both checks generated a phone call from the credit companies (Bank of America and CitiBank) to ensure they were legitimate.

Help them get a family squared away quickly by answering all incoming emails and phones calls as soon as possible.

Calling - and then there's this option.

I'm not saying it's the right call or not, but if you try other things and can't get results you either move to another place or take the 'legal' route....that could be another option is ask them if they have another unit you could move into.

For me, it would be how do they source deal flow - cold calling, google ads, fb ads, etc. 

Yet should we call you a predator?
