I was considering getting my brokers license ( MI requirement is 3 yrs in RE and Builders Lic. counts towards that) but not sure if it can negatively affect my investment business.

Especially if there are other roommates in the mix that may be negatively affected by this situation and may want to leave to get away from it.

OP, you lucked out with this hateful nutjob choosing not to rent from you.And, no, I would not believe a non-paying tenant's story that their landlord didn't have the deposit/etc. without verifying the landlord's negative reputation in the court system.

When I first started considering buying, about 1984, OO rates were 15% and negative amortization was common.  

My previous post and this one, while perhaps sounding negative, mean only that it's tougher to find good deals in Phx/Tucson with so much competition driving prices up.

I know our agency really does not care to report ANYTHING but what is required to mortgage companies, meaning we're not interested in getting you in trouble with them, but you do need to report to us when you quit claim to an LLC.There is case law in many states that shows when you quit claim to an LLC you negated your insurance policy that was in your name. 

Generally permits mean nothing, and having them does not provide any protection, other than the fact that NOT having them is a negative indicator that will go against you because a lawyer can insinuate very easily that you did shoddy work and were cutting corners.If you are careful about how you do things, and yes even how you treat people, you are less likely to be sued and found negligent.

The points given can range from a negative 2 to a positive 2.

I live in a 611sf studio worth $1mil, would rent for $3k (would be negative cash flow for an investor).

I know we calculated the cash flow on other bay area properties and they turn out to barely break even or negative.
