Everyone seems to have a different opinion of this. I really don't like leases as they can create considerable problems for both parties. If both sides agree to a lease, in my opinion it should be valued at the cost ....principal, interest, taxes, insurance. As a buyer, I would want the sellers out of the house when you close. That way you can do a walkthru and ensure everything is as you expected. Cleaned, painted, no holes in the walls, grass cut, etc. If it is not as you expected then you can hold up closing until it is done. If you close and lease back to seller and then find these issues when you get in, there's not a lot you can do to force the issue. Also I've seen sellers who are not ready to move.....what happens if they have no place to go, what happens if their new house is not ready or they can't close on it. They'll want to camp on you. That is typically not worth the hassel.....at $25 or $50 or $100/day .
