Why don't you talk to your landlord and see if you can work something out? Maybe they will be willing to accept the money you have and let you "work off" the rest. Maybe you can help do some of the renovations (painting, cleaning, etc.) for a reduced cost of the house. There are many possibilities if you just talk about them. It's worth a try. The worst that can happen is he will not be willing to negotiate and then you will have to move.
