I rent an office in a small office building in Connecticut. I've leased this office for many years and currently don't have a lease. The owner of the building has decided to sell, and the new buyer has contacted me and asked me to sign a lease.
There is absolutely no benefit to me to signing a lease. Office space is plentiful locally, so the new owner needs me more than I need them. However, the buyer informed me today that if I don't sign a lease, the mortgage won't be approved. I don't want to be the guy who killed a real estate deal and end up with both the current owner and future owner mad at me. So the buyer proposed writing a contract "on the side" between us that releases me from the lease if I provide 90 days notice. The mortgage lender would be unaware of this contract. I'm amenable to that, but it raises some questions:
Concealing the contract from the mortgage company is probably credit fraud of sorts, but my view is that's the buyer's problem, not mine. Am I correct on that?
Would it be a legal, enforceable contract? If I give 90 days' notice and the landlord refuses to release me from the lease, would a court find in my favor?
Am I missing other legal pitfalls?
