Fixed Rate Mortgage
A mortgage with the same interest rate for the entire loan term — no adjustments, no rate shock, fully predictable payments.
What is a fixed-rate mortgage?
A fixed-rate mortgage is a loan whose interest rate is locked in at origination and remains the same for the entire term. Principal, Interest, and the loan’s amortization schedule never change — only the property tax and insurance escrow components of PITIA can shift year over year. From day one to the final payment, the borrower knows exactly what the rate is.
Three common terms exist in the U.S. mortgage market: 15-year, 30-year, and (less commonly) 40-year. The 30-year fixed is by far the most common — it offers a moderate monthly payment while spreading amortization over a long enough horizon to be affordable. The 15-year builds equity twice as fast and carries a slightly lower rate, but the higher monthly payment limits its use to borrowers with strong cash flow.
Fixed-rate mortgages eliminate the “rate shock” risk that comes with ARMs — the borrower never faces a payment increase because of an adjustment. This makes them the default choice for long-hold investors, primary residence borrowers, and anyone who prioritizes payment certainty.

FAQs
What's the most common fixed-rate term?
The 30-year fixed is the standard mortgage in the U.S. — it amortizes over 30 years with the same rate the whole way through. TQL offers 15-year, 30-year, and 40-year fixed terms (the 40-year is only available when combined with an interest-only feature on eligible programs).
Is fixed-rate better than an ARM?
Better' depends on your hold horizon. Fixed gives you certainty for the full loan life — no adjustment risk, no rate-shock scenario. ARMs offer a lower introductory rate but reset to market after the fixed period ends. Long-hold investors and primary-residence borrowers typically prefer fixed; short-hold investors with a clear exit plan often pick ARMs.
What's a 40-year fixed mortgage?
A 40-year fixed loan amortizes principal over 40 years instead of 30. The monthly payment is lower than a 30-year on the same loan amount because principal pay-down is stretched out further. TQL offers 40-year fixed only when paired with a 10-year interest-only period on the front end — useful for maximizing cash flow on a long-hold rental property.
