If you are able to come up with a 20 percent down payment, you’d reap quite a few benefits. Putting that larger amount down lets you avoid paying private mortgage insurance (PMI), it can help you qualify for a lower interest rate (which can help you save thousands over the life of your loan), it’ll give you more equity faster, and it will result in a smaller monthly mortgage payment. Depending on where you’re looking to buy a home, a larger down payment might also help you be a competitive buyer and stand out to the seller if there are multiple offers on the home.
Down payment size is a function of three overlapping factors: your desired initial loan-to-value (LTV) ratio, your time horizon (when you want to buy), and local housing market conditions. When people talk about budgeting for a future home purchase, they generally refer to list prices: “We’re willing to pay $300,000,” or “We can afford $250,000, but no more.”
For lenders, whether it’s a bank, credit union, or other type of lender, a down payment helps offset their risk in making a mortgage loan because it means the borrower immediately has some skin in the game–an investment to protect. The more money you pay down, the less the lender stands to lose if you default on payments and the lender has to foreclose, especially early in the loan term. This is why borrowers who put less than 20 percent down usually have to get PMI, as it protects lenders by repaying the unpaid portion of the loan if the borrower defaults.
"Down payment": It's amazing that these two little words have such a profound influence on your homeownership process—and your life! Ask most people what is an acceptable down payment on a house, and nine times out 10 they'll tell you it's 20% of your home's selling price. So you do the math, figure you'd have to put down $50,000 on a $250,000 house, and break out in hives when you realize that the chances of your getting out of that tiny one-bedroom apartment are slim.
