As the home will be your future home and as you are the tenant, you will be responsible for the upkeep of the property.
Before any Rent to Own program is started, there is a Home Inspection completed. This Inspection is to ensure all parties to the program understand the condition of the home.
If there any repairs to be done before or after close, the repair schedule is agreed to before the program starts. This schedule will outline the repairs, estimated costs and who will be responsible for their completion.
Once the program starts, the maintenance of the property will be as detailed in the Lease Agreement between the Tenant and the Investor/Funder.
Again, this will be your future home so keeping it in a good state of repair will benefit you are the end!
