$300,000 mortgage FAQ

What is the monthly payment on a $300,000 mortgage?
At the current 30-year fixed average of 6.76 percent, a $300,000 mortgage costs about $1,948 a month in principal and interest. Over a 15-year term at 6.09 percent the payment rises to roughly $2,546. Property taxes, homeowner insurance and any PMI or HOA dues are added on top of these figures.
How much interest will I pay on a $300,000 mortgage?
A 30-year $300,000 mortgage at 6.76 percent costs about $401,204 in total interest — more than the amount borrowed. Choosing a 15-year term at 6.09 percent cuts that to roughly $158,313, a saving of about $242,891, in exchange for a higher monthly payment.
What income do I need for a $300,000 mortgage?
Lenders commonly want your total housing payment to stay under 28 percent of gross monthly income. On that rule the $1,948 payment for a $300,000 mortgage implies an income of roughly $83,477 a year before tax — and more once you add property taxes and insurance, which the 28 percent test also counts.
What house price does a $300,000 mortgage buy?
It depends on your down payment. Borrowing $300,000 with 20 percent down corresponds to a purchase price of about $375,000, while 10 percent down puts the price near $333,333. A down payment below 20 percent on a conventional loan also adds PMI until you reach 20 percent equity.
How much does the interest rate change a $300,000 payment?
A great deal. On a 30-year term each quarter-point of rate moves the payment on a $300,000 mortgage by roughly $50 a month. The table on this page prices the loan from 5.00 percent to 8.00 percent so you can see the full range before you lock a rate.
