The contractor is supposed to know what requires a permit and what doesn't.Now you know. 

After some discussion in which I advised security deposit was held on behalf of both parties, he withdrew request until end of lease in September.I have advised girlfriend of his call, and she then stated that the security deposit monies really belongs to her.My dilemma is that the lease is coming to an end, and I understand that in PA, a landlord is required to return 1 month security deposit if lease is to be extended.The place has not been vandalised and is basically being taken care of, and I'm willing to renew lease with the girlfriend, who very interested in renewing lease, but who also now appears to have allowed a new boyfriend to move in.I suppose I could have this situation handled by hiring a lawyer, but my challenge is how should I go about retaining at least 1 month security deposit while returning the other. 

and a house hack is not supposed to cash flow. 

First, I need to learn how to protect myself and my current tenant against some of the issues I've seen online where renters will stay past the date they're supposed to leave.

I believe you are supposed to register your out of state LLC in each state that is does business in though.

If you are planning on buying a turnkey property anyway, I suppose it could provide some insight into the locations they are working in and as I said above, if you did buy a property through them...the academy fee is refunded.Definitely don't take my word for it but it's helped me so far. 

Again section 8 recipient are supposed to have high barriers to housing such as a permanent disability or something else.

I suppose they could call the underground AirBnB operations "DareBnB."  

The contract was supposed to expire back on April 30, 2024, but they still haven't removed their machines despite the fact that I sent the termination notice a year ago by certified mail, which they also acknowledged receipt of in an email. 

Think about it simply like this, if you moved into a place that was supposed to be good to go, and the water wasn't, almost got people sick.
