Financing Kentucky One Home at a Time
It is possible to sell the home with the lease in place - new owners take over lease until expiration under current terms and attorneys pro-rata payments to assign to new owner at close - alternatively you can buy tenant out of the lease.
With it only being six months I am certain this will not put any buyers off making offer on the home. You will need to check the lease and see if there is a show clause in there for the cottage and get permission to show.
If you need any other advice pricing home etc please give me a call.
