Mortgage Default Triggers Full Balance

After missing three monthly payments Alliance Holdings sent written notice declaring the entire unpaid balance immediately due. Anderson tendered only the arrears but the lender rejected the partial payment and initiated foreclosure proceedings seeking the full accelerated amount.
Strict Enforcement After Notice
