Once his name is added, can he sell it and claim the full 121 exemption for taxes (of up to 250k for single people), since he’s lived in the place for two years and it’s his primary residence?

I asked my RE agent and he can’t allow me to use any of their companies sales docs, nor can he give me advice/guidance on a property he’s not an agent on or that’s not listed on the MLS. 

However he is very careful about leveraging his personal residence which he pays extra to become debt free as soon as he can. He

Can he do that if I take possession and finish the eviction?

Does he have to get a $200k mortgage to stay taxe free or can he come out of pocket for the other $200k and pay $300k cash for new property B?

You are lending money to a stranger that you do not know their credit history (why can he not get a normal loan?? 

The house will need to be completely gutted, doesn't even have CAC (we live in GA so will need that), needs completely new electrical, taking down walls, rearranging of bedrooms, replace windows and doors, enclosing the carport to a garage, it needs a ton of work.  

He called me and said he will not vacate as he has done nothing wrong and I can try to evict him if I want but doubts that I can. He

He can’t stop the agreement...can he?

I have a friend who is a broken here in NY , a home in the Dominican Republic has been brought to his attention and he is trying to sell it . Is that legal or would he face consequences ?
