How much am I supposed to put down?
A down payment is the amount of money that you pay at the time of purchase towards the price of your home. When buying a home, the minimum down payment is at least 5% of the purchase price.
For Example: To buy a home that costs $250,000 you will need a minimum of $12,500 as your down payment.
If your down payment is less than 20%, you will have to purchase mortgage default insurance, which could add to your costs. Save as much as you can for your down payment. A larger down payment means you need a smaller mortgage, which will save you thousands in interest charges!
