What a Rate Buydown Is
Paying "points" to lower your mortgage rate is called a buydown. One point equals 1% of the loan amount. In exchange for paying that upfront, the lender gives you a lower interest rate.
The question is whether the upfront cost is worth the ongoing savings.
The Breakeven Calculation
The math is straightforward:
Breakeven = Upfront Cost ÷ Monthly Savings
If you pay $3,000 to lower your rate and save $75/month, your breakeven is 40 months — just over 3 years. If you stay in the home longer than that, the buydown paid off. If you sell or refinance before then, you lost money on the deal.
When Buydowns Make Sense
You're confident you'll stay long-term. If you're buying a forever home and have no plans to move or refinance, a buydown can make sense — especially if you have the cash available and the breakeven is under 5 years.
Rates are elevated and you don't expect to refinance soon. In a high-rate environment where refinancing in the near term seems unlikely, locking in a lower rate upfront has more value.
The seller is offering a concession. If a seller is willing to contribute to closing costs, using that money for a rate buydown (rather than a price reduction) can sometimes produce better long-term value.
When Buydowns Don't Make Sense
You expect to refinance within a few years. If rates drop and you refinance, the buydown money is gone. You paid for a rate you no longer have.
You need the cash for other purposes. Down payment, reserves, and closing costs all compete for the same dollars. Depleting reserves to buy down a rate is rarely the right tradeoff.
The breakeven is too long. If you're looking at a 7–10 year breakeven, the buydown is speculative at best.
Temporary Buydowns (2-1 Buydown)
A 2-1 buydown is a different structure — the rate is temporarily reduced for the first two years (2% lower in year 1, 1% lower in year 2, then back to the note rate in year 3). These are often seller-funded and can make sense in specific market conditions.
The key is that you need to qualify at the full note rate, not the temporary reduced rate.
The Honest Answer
Whether a buydown makes sense depends entirely on your specific numbers, timeline, and cash position. There's no universal answer. Run the breakeven calculation, consider your realistic timeline, and make the decision based on your actual situation — not on the appeal of a lower rate.
