Mortgage Payment at 7.18%: What $300K, $400K and $500K Loans Cost

Answer first: A 30-year fixed mortgage at 7.18% has estimated monthly principal-and-interest payments of $2,032 on $300,000, $2,710 on $400,000 and $3,387 on $500,000. Those figures exclude property tax, homeowners insurance, mortgage insurance, HOA dues and maintenance. Freddie Mac reported 7.18% for the week of November 5, 2026; it is a benchmark, not a rate every applicant can obtain.

Payment table for a 30-year mortgage at 7.18%

These estimates use the standard fixed-rate amortization formula, 360 monthly payments and no extra principal. The loan amount is the financed principal—not the home price. Figures are rounded to the nearest dollar, so a lender’s disclosure may differ slightly.

*Assumes all scheduled payments are made and the loan is never sold, refinanced or prepaid. Actual lifetime interest changes when the loan ends early or extra principal is applied.

Enter your down payment, term and local ownership costs in the mortgage calculator. If the purchase price is still undecided, use the affordability calculator and then stress-test the result with the debt-to-income calculator.

Why your quote may not be 7.18%

Freddie Mac’s Primary Mortgage Market Survey is built from thousands of conventional, conforming, fully amortizing purchase-loan applications submitted through Loan Product Advisor. Its published profile emphasizes borrowers with excellent credit and 20% down. It is useful for tracking direction, but it is not an APR, approval, lock confirmation or individualized offer.

Lenders price credit score, loan-to-value ratio, property type, occupancy, points, loan size, lock period and market conditions. FHA, VA, USDA, jumbo and investment-property loans can price differently. Ask multiple lenders for the same loan amount, property assumptions, lock period and point structure so the comparison is meaningful.

The full payment is larger than principal and interest

Property tax

Property taxes are local and can change after a sale, reassessment, new construction or expiration of an exemption. The seller’s current bill may not predict your future escrow deposit. Ask for the latest bill and verify the assessment rules with the local taxing authority.

Homeowners and hazard insurance

Insurance depends on replacement cost, location, deductible and hazard exposure. Obtain a property-specific quote before making a final affordability decision. Flood, wind, earthquake or wildfire coverage may be separate and can materially change the monthly total.

Mortgage insurance and HOA dues

Conventional loans above 80% loan-to-value may include private mortgage insurance, while FHA loans generally follow mortgage-insurance-premium rules. HOA and condo dues are not part of the mortgage formula but still count in the household budget and often in underwriting. Model conventional PMI with the PMI removal calculator.

Rate sensitivity on a $400,000 mortgage

A rate reduction is not automatically free. Discount points exchange more cash at closing for a lower note rate. Calculate the months required to recover that upfront cost with the points buydown calculator. A temporary buydown only subsidizes early payments; it does not change the permanent note rate.

30-year at 7.18% versus 15-year at 6.57%

Freddie Mac’s November 5 average for a 15-year fixed mortgage was 6.57%. On a $400,000 balance, the estimated 15-year P&I is about $3,500 per month versus $2,710 for the 30-year loan. The shorter term is roughly $790 more each month, but scheduled lifetime interest is about $229,971 instead of $575,506.

The lower lifetime interest comes from repaying principal much faster, not merely from the lower rate. A 15-year term can strain monthly cash flow and reduce room for emergencies, retirement saving or repairs. Compare the required payment rather than assuming the shorter term is always better. The mortgage comparison calculator can keep the terms side by side.

Should you lock, float or wait?

A rate lock can protect a quoted rate for a defined period, but terms, fees and extension rules vary. Floating preserves the chance to benefit from a decline while accepting the risk of a higher payment before closing. Ask what happens if closing is delayed, whether a float-down option exists, and which changes to the application could invalidate pricing.

Waiting to buy is broader than waiting to lock. Home prices, inventory, rent, insurance and personal finances may move while rates change. “Buy now and refinance later” is not a guarantee because a future refinance requires acceptable rates, equity, credit, income and closing costs. The current payment should be affordable without depending on that future transaction.

How to compare lender offers correctly

1. Request comparable quotes. Use the same loan amount, term, down payment, points and lock period.
2. Read the Loan Estimate. Compare interest rate, APR, projected payments, lender-controlled fees, lender credits and cash to close.
3. Separate points from other costs. A lower rate with expensive points may lose to a zero-point option if you move or refinance early.
4. Verify taxes and insurance. Estimates can be too low for the actual property.
5. Keep reserves. Do not use every available dollar for the down payment and closing costs.
6. Recheck before closing. Review the Closing Disclosure and ask about unexplained changes.

The CFPB recommends comparing official Loan Estimates rather than relying on verbal quotes. Use the closing-cost calculator to organize estimates, but treat lender disclosures and property-specific bills as the controlling documents.
