$300,000 mortgage FAQ
- What is the monthly payment on a $300,000 mortgage?
- At the current 30-year fixed average of 7.28 percent, a $300,000 mortgage costs about $2,053 a month in principal and interest. Over a 15-year term at 6.60 percent the payment rises to roughly $2,630. 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 7.28 percent costs about $438,949 in total interest — more than the amount borrowed. Choosing a 15-year term at 6.60 percent cuts that to roughly $173,372, a saving of about $265,578, 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 $2,053 payment for a $300,000 mortgage implies an income of roughly $87,970 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 $51 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.
