The least amount in a down payment is an attractive option when people are thinking of buying a home. A common reason is to have cash available for furnishing the new home and possible unexpected expenses.
Some people don’t have any options because they only have enough for a minimum down payment and the closing costs. For those fortunate buyers who do have extra money available, let’s look at why you’d want to do such a thing.
Most loans in excess of 80% loan to value require mortgage insurance to protect the lenders for the upper portion of the loan if the home were to go 
into foreclosure. FHA requires an up-front premium of 1.75% of the amount borrowed plus a monthly amount of .85% on the balance. FHA mortgage insurance premium must be paid for the life of the loan.
Mortgage insurance on conventional loans varies depending on the borrowers’ credit and the amount of down payment being made. Unlike FHA, when the unpaid balance reaches 78% of the original amount borrowed, the mortgage insurance is no longer needed. If the home enjoys rapid appreciation, after a period, the lender may allow the borrower to get an appraisal to show that the unpaid balance is now less that 78% of the current appraised value.
The premium for mortgage insurance on conventional loans can be paid as a single premium upfront in cash or financed into the mortgage. A second option would be monthly mortgage insurance included in the payment until it is no longer needed. A third option could be lender-paid MI where the cost is included in the mortgage interest rate for the life of the loan.
VA loans do not require mortgage insurance but there is a one-time funding fee of 2.3% that can be paid in cash at closing or added to the amount borrowed. Disabled veterans and Purple Heart recipients are not required to pay the funding fee.
Putting at least 20% down payment on a home not only will avoid the mortgage insurance, it could also help you to get a little lower interest rate. Since the loan to value is lower, there is less risk for the lender.
A $350,000 with a 10% down payment at 4% interest could have a monthly mortgage insurance cost between $70 to $130. A trusted mortgage professional can help you assess the options you have available. It is always better to make some of these decisions before you start shopping for a home.
