Buying a home can fit a FIRE plan at a high mortgage rate if the full cost is sustainable and leaves enough accessible money for the rest of life. Renting can also be a deliberate route to financial independence. The deciding comparison is between two complete household plans, not between rent and a mortgage payment stripped of taxes, insurance, repairs, and a down payment.
What changed in early October?
Freddie Mac’s October 8, 2026 survey put the average 30-year fixed mortgage rate at 7.40%, up from 7.28% on October 1. Those dated national averages provide context for the recent housing headlines. They are not a rate quote for a particular buyer or a prediction of where borrowing costs go next.
Credit profile, down payment, loan type, points, and other terms affect the offer you receive. The Consumer Financial Protection Bureau recommends comparing Loan Estimates because fees and closing costs matter alongside the rate. A lower advertised rate can require paying more upfront.

How much does the rate change the payment?
For an illustrative $300,000 loan amortized over 30 years with a fixed rate, principal and interest are about $1,799 a month at 6%, $2,077 at 7.4%, and $2,201 at 8%. These calculations exclude every ownership cost outside the loan. They assume 360 equal monthly payments with no extra principal.
The unrounded difference between the 6% and 7.4% examples is about $278.49 a month, or $3,341.85 a year. If take-home income and every other expense stay constant, that difference comes out of saving or discretionary spending. It need not end a FIRE plan, but it should appear somewhere in it.
| Fixed annual rate | Monthly principal and interest | Annual principal and interest |
|---|---|---|
| 6.0% | $1,799 | $21,584 |
| 7.4% | $2,077 | $24,926 |
| 8.0% | $2,201 | $26,416 |

Is rent really money thrown away?
Rent buys housing and some flexibility; a mortgage payment buys housing finance and, gradually, equity. Neither label tells you the entire economic cost. Compare rent and renters insurance with mortgage interest, property taxes, owners insurance, maintenance, association fees, transaction costs, and the return forgone on cash tied up in the purchase.
Principal repayment builds equity, so it is different from interest as an economic expense. It still leaves your checking account every month and must fit the cash-flow plan. Counting all principal as permanently consumed overstates the ownership cost; pretending it requires no monthly funding understates the payment burden.
Use the likely length of stay. Buying and selling costs have fewer years to spread over if a new job, family need, or change of location arrives soon. A home that supports community and stability can be worth its cost even when a spreadsheet prefers renting. Make that tradeoff explicit instead of promising the purchase will always outperform.
Can home equity count toward my FIRE number?
Include home equity in a net-worth statement. Treat it as retirement spending capital only when you have a concrete way to use it, with housing afterward accounted for. A plan to sell and downsize can release money; continuing to live in the same home does not turn its estimated value into monthly cash.
For example, a household with $700,000 invested and $500,000 of home equity has $1.2 million in those assets. If it plans to stay in the house, applying a portfolio withdrawal rule to the full $1.2 million misstates the assets available to sell for groceries. Rent from a property is another case and requires costs, vacancies, and taxes before it becomes spendable income.
Likewise, a down payment reduces accessible investments today. Model the lower starting investment balance and the new monthly saving capacity together. A home can reduce future housing uncertainty while leaving a household too cash-constrained to handle repairs or a job interruption.
Should I assume I can refinance later?
Use the payment you can obtain and afford now in the base case. A later refinance depends on rates, qualification, property value, and costs. If the purchase only works after a hypothetical refinance, the affordability calculation relies on an event you do not control.
Also distinguish a new mortgage from an existing one. Higher market rates do not reset the principal-and-interest payment on a standard fixed-rate loan you already hold, although taxes and insurance can change. Paying extra principal may reduce interest and the payoff time without reducing the required payment unless the lender provides an applicable recast or the loan is refinanced.
For FIRE planning, mark when the mortgage ends and which expenses remain. The simple planner holds real spending constant, so a single spending number cannot exactly represent a nominal fixed payment that ends halfway through retirement. Keep a separate housing schedule when the payoff date is material.
