Last week she recalled the February month rent saying that she didn't authorized the February rent..

I found out there is a current mortgage, talked with the company, but they won't give me any info because I'm not authorized. 

The Texas Business Organizations Code is quite explicit on the protection available to LLC's and incorporates it into the code authorizing series.

Even if they do, you have proof the house is yours and you are occupying it with keys to the door, so the police won't have the authority to evict you.

Does he have work authorization ?

I have a clause that authorizes me to contact that person in case of "death, incapacitation, or incarceration" and work with that individual to coordinate removal of belongings, payment of rent, or even a refund of deposit.When someone dies alone, there is always a police investigation to ensure no foul play.

Four units at $65 on MTM leases and two units are rented to the city housing authority at $700 with annual leases. 

I would also recommend you reach out to your local county housing authority.

I can pre-authorize an amount and if the expense is below that, the vendor can do the repairs without talking to me live4) Urgent maintenance issues - say a pipe breaks, or tenant is locked out.

Who markets the property, sets the rent rate, signs the lease, authorizes maintenance, etc?
