Mortgage riders are common with any type of mortgage, be it a first or a second mortgage. Riders are put in place to allow the lender — who is also a stakeholder — to maintain a certain level of control concerning the usage of the property.
A rider acts as an addendum to a mortgage. The language in the rider is specific to the lender. It requires require certain agreements from the borrower in relation to on-time payment of homeowner association assessments or laws regulating renting or sub-leasing a property. The language in a rider will also be placed on the deed of trust, which is an instrument used by lenders to foreclose if the owner violates the terms of the deed or the attached rider.
If a borrower violates the terms of the rider, the lender can foreclose by calling the rider clause due. In these circumstances, it does not matter if the borrower has made timely payments on the mortgage or upheld all other terms of the mortgage. Violation of the rider is enough to allow the lender to pursue a foreclosure filing.
