How a 3-2-1 Buydown Can Save You Thousands in San Diego’s Real Estate Market

ADVICE June 13, 2025

Let’s be real—interest rates sitting around 6.5% have made many San Diego homebuyers pump the brakes. But there's a powerful tool buyers (and savvy agents) are using in 2025 to ease into homeownership without waiting for rates to drop: the 3-2-1 buydown.

This strategy can significantly lower your monthly payments for the first three years, giving you the breathing room you need to settle in, build equity, and plan ahead.

💡 What Is a 3-2-1 Buydown?

A 3-2-1 buydown is a seller-paid or lender-paid option that temporarily reduces your interest rate for the first 3 years of your loan:

Year 1: Interest rate is 3% lower than the current market rate
Year 2: Interest rate is 2% lower
Year 3: Interest rate is 1% lower
Year 4 and beyond: Loan resets to the full rate (in today’s market, 6.5%)

This setup gives buyers significant upfront savings and a smoother transition into full payments.

📍 Why It’s Perfect for San Diego Buyers

In a competitive (but slightly softening) market like San Diego, buyers can take advantage of buydown credits to secure lower monthly payments—saving thousands in the first few years without waiting for rates to drop. It’s one of the smartest ways to stretch your budget and get into the home you want now.

It’s also a great fit for:

First-time buyers juggling move-in costs
Buyers expecting to refinance in the next 2–3 years
Anyone who wants lower payments now, not “someday”

🔍 San Diego Case Study: $750,000 Home with a 3-2-1 Buydown

Let’s look at a real-world scenario.

Home Price: $750,000
Down Payment: 20% ($150,000)
Loan Amount: $600,000
Interest Rate: 6.5%
Loan Type: 30-Year Fixed
Buydown Program: 3-2-1 buydown (seller credit ~$17,000)
Estimated Taxes & Insurance: $900/month

🧾 Monthly Mortgage Payments (Principal + Interest Only)

Year	Effective Rate	Monthly P&I	Est. Monthly PITI
Year 1	3.5%	$2,694	~$3,594
Year 2	4.5%	$3,040	~$3,940
Year 3	5.5%	$3,408	~$4,308
Year 4+	6.5%	$3,792	~$4,692

🏦 Total Savings Over First 3 Years vs. Paying 6.5% from Day One:

$13,176 + $9,048 + $4,608 = $26,832 in total payment savings

All this with a seller credit of around $17,000—far more impactful than a price drop and a win-win for both sides.
