What I suspect is that you "inherited it" but that when you transferred title into your name the deed showed $1 because that is allowed for close family transfers and avoids state transfer tax aka tax stamps on the sale.

As for selling with 10% down at 8% interest, you now have two title transfers that violate the due on sale clause and add complications to subject to “safeguards” that reduce risk if note is accelerated, if party in possession doesn’t pay taxes or insurance, and of triggering whatever system the lender has set up to notify them when a deed transfer takes place.

However, they include "bad boy" carve-outs that trigger full recourse if the borrower commits certain bad acts like fraud or voluntary bankruptcy filing.Abandonment may constitute default: If the GP abandons or surrenders control of the property during foreclosure, it could be considered an unpermitted transfer that violates the loan agreement and triggers the guarantor's full recourse liability for the unpaid loan balance.
