Sticky stiuation - I need some innovative strategies

Okay, I have a out of state owner, that has a VA loan on a property he lease optioned it out and now regrets it because the new tenant has brought in 7 dogs. Any way I am going to look over the lease to see if I can get the tenant out of the lease and option. But if I take it over I am thinking of doing it Subject to, and re-renting the house out.

Any other ideas would be great as well as ideas on how to get this person out of their lease and option. Also anyone know if VA loans have due on sale clauses, or is it a good idea to leave title in the mortgage holders name and hold a quit claim deed that seller signs, but is not filed, until I am ready to pay off the mortgage?
