Co-Lessee Wants Out

[Michael Campione]

Hi all.

Forgive me if this is a bit convoluted. There's more.

My girlfriend just purchased a duplex in the Dallas area. When we originally looked at it the one tenant told us his roommate had recently moved out and he would like to eventually get out of the lease. (His lease is up in four months).

After she purchased it we discussed with the remaining tenant that this was possible but only after we found a suitable tenant and that he and his roommate were still bound by the original terms of the lease (the rent they were paying is a bit low anyway). Also apparently the roommate is covering the rent.

I just got a call and an email from the roommate that moved out giving me 30 day notice. Also he asked for a copy of the lease. (Trying to get the originals from the previous owner) we have crappy faxes.

How would the security deposit be handled in this case?
Also if the security deposit was not included in the HUD1 at sale is the previous owner responsible?
