How much should I put down on a house?
Put down what fits your savings and still leaves cash in reserve. We’ll show you the payment at each level.
Do I need 20% down?
No. Many programs accept far less. Under 20% usually adds mortgage insurance. We’ll show you the trade-off.
What is the difference between down payment and closing costs?
Your down payment lowers your loan. Closing costs pay for the lender, title, appraisal and other services. You need cash for both.
Where can my down payment come from?
Depending on the program: savings, gifts or assistance. Your loan officer confirms what applies.
Does more down lower mortgage insurance?
Often yes. A bigger down payment shrinks the loan the insurance is based on. Some programs drop it at higher levels. We’ll confirm for your loan.
Is a calculator the same as pre-approval?
A calculator gives an estimate. Pre-approval checks your income, credit and assets. We can pre-approve you in one day.
