The objective of an 80-10-10 mortgage is to avoid the expense of mortgage insurance for buyers wanting a 90% loan. A buyer can obtain an 80% first mortgage and a 10% second mortgage with a 10% down payment and not be required to have private mortgage insurance.
For example, a buyer could put $30,000 down on a home priced at $300,000 and get an 80% first mortgage without mortgage insurance. The borrower could get a second mortgage, either through the same lender or a third party.
In the example, the 80-10-10 would save a buyer $193.71 per month which can be a considerable amount of money over a ten-year period. The interest rate on the second loan will be higher than the first because there is more risk.
Helping buyers make better choices is a valuable service real estate professionals can provide. Having the right tools and information can make the decisions easier to understand. Using an 80-10-10 calculator, you can see what the savings might be for your situation.
