In theory if one of these deals went to litigation (thankfully, I've never personally seen that), I suspect the "winner" would be whoever pays for the most expensive lawyer, because obviously there is a reason most folks use contracts that have been checked out by lawyers. 

Here's my problem:My moms been house hacking for a couple years but recently we've gotten complaints from neighbors about our tenants(roommates) and how we are not a single "last name" family and suspected of doing business rentals. 

Though Brandon's plan is not nearly as crazy or whimsical as what was typically being discussed in 2006, so it's not at all crazy for a tentative plan and I suspect will play out just as planned.But, to your latter question, a refinance is essentially a "re-mortgage."

If property is determined to be abandoned under the lease and in accordance with Texas law, notice will be posted at property of suspected property abandonment giving tenant 3 days to remedy lease violation.

This is more than likely, what you suspect.  

But it they just renovated it, I would suspect they would want to get their money back out...On a side note, for 1-4 families we typically talk about cash on cash return .

With a week to go before closing, I suspect that your financing contingency has already expired.If you're only on the hook for $1,000 and are positive you want out, consider yourself lucky.  

I suspect that he's going to need it.

not to mention anyone trying to raise money at 5k at a time is suspect unless its a full blown nationwide crowdfunder who have created that niche.On the references  that I don't worry about much.. one.. if its a scam references are schills..

I suspect @Shawn Corcoran is incorrect when he says Quit claim deeds are useless in TX.
