Just trying to do a little do diligence not trying to be a wise guy here. Does the prospective buyer have to agree to assume your lease or is there an ability for the homeowner to terminate the lease upon the sale of said property??
The new buyer has the opportunity to assume the rest of the lease from the seller, thereby getting the same savings that the original owner had on their utility bill. Depending on how long it has been since the original lease was signed and the typical annual inflation rate, the new buyer will be getting an even better deal comparatively than the original owner. FYI I researched this with a local realtor before signing my contract. She explained that here in Colorado with our 300+ sunny days it is a very positive thing to offer to buyers since most folks much prefer supporting green energy from solar, rather than buying gas-produced energy from Xcel. This is why companies like Shea homes are pre-installing leased solar systems on much of their new construction.
