The due-on clause is called an alienation clause, and the call is referred to as an acceleration of the note balance.The due-on clause is triggered by: any conveyance of ownership, including land sales contracts; origination (except home equity loans) or foreclosure of junior trust deeds on the property; or the creation of a lease for more than three years, or any lease with an option to buy. [12 Code of Federal Regulations §591.2(b)]The carryback AITD transaction, of course, involves both a sale (the grant deed) and a further encumbrance (the trust deed).Thus, an AITD transaction triggers the due-on clause in any underlying trust deed, allowing the lender to: call or recast the loan unless written consent to the sale has been given; or fail to act on the right to call after notice of the transaction, called a waiver.Thus, when current market interest rates are high and the AITD is most beneficial to both the buyer and the seller, a senior trust deed lender is likely to call the underlying loan due on the sale.

I was never informed of this until recently and I don't know how he could have sold my property without my consent but it may have been another scam he could have planned on the potential buyer.Ironically, I got the news of McNutt's arrest from another management company I hired after McNutt and terminated also within a short period of time because they were going out of business without telling me ahead of time.

You could with consent of the owner, actually having them lease it to them.
