" The flood insurance is put into escrow, so it is factored into your monthly P&I. I'm not sure what happens once you pay off your mortgage. I assume you could drop the flood insurance. Not sure why you would want to though."
My experience was that once I had 20% equity in my house I was allowed by the bank to cancel my mortgage insurance, which as I understand it was in place to protect the bank in case I was abducted by aliens and stopped making my mortgage payment. The housing market drove up the value of my equity faster than my monthly payments did, and as soon as I hit that 20% mark I asked the bank to stop taking payments for mortgage insurance. They did; they are REQUIRED TO, but only if you ASK. Otherwise the bank will happily collect that "insurance" for the entire term of the mortgage, in my case 30 years.
But that was not flood or disaster insurance, it was only "mortgage insurance." As the purchaser of the property, it was up to me to decide how much protection I wanted to have.
At that time in my life I was happy to save the few extra bucks that the mortgage insurance cost; looking back I would have been wiser to apply even that small amount to paying down the principal of the loan, the house would have been paid for even earlier than it was (but I still did it in less than 30 years, saving thousands of dollars in interest by doing so.)
