If you are eyeing a home in Encinitas but today’s rates feel steep, an interest rate buydown can help calm the monthly payment. You are not alone in wanting clarity on how these work or whether they are worth it. In this guide, you will learn the difference between temporary and permanent buydowns, how to compare costs, and what local factors in coastal North County can change the math. By the end, you will have a simple checklist to make a confident decision with your lender and agent. Let’s dive in.
What is a buydown?
A buydown lowers the interest portion of your mortgage payment by prepaying some interest. It can be temporary for the first year or two, or permanent for the life of the loan. The funds can come from you, the seller, a builder, or sometimes through lender credits.
A buydown only changes principal and interest. It does not reduce property taxes, homeowners insurance, or HOA dues that are common in many Encinitas neighborhoods.
Temporary buydowns explained
A temporary buydown uses an escrowed subsidy to reduce your effective interest rate for a set time, often 1 to 2 years.
- 2-1 buydown: Year 1 is 2 percent below the note rate, Year 2 is 1 percent below, then the payment resets to the full note rate.
- 1-0 buydown: Year 1 is 1 percent below, then it resets to the note rate.
Pros:
- Lowers your first-year or second-year payments, which can help with move-in costs.
- Useful if you expect income to rise or want time to adjust before full payments.
Cons:
- It is temporary, so payments increase when the subsidy ends.
- Many lenders qualify you using the full note rate, not the reduced buydown rate, so it may not improve your ability to qualify.
- Counts as a seller concession when a seller funds it, which must fit program limits.
Permanent buydowns with points
A permanent buydown means you or the seller pay discount points at closing to reduce the rate for the entire loan term. One point equals 1 percent of the loan amount. Lenders publish how many points buy how much rate reduction, and it varies by day and loan.
Pros:
- Permanent monthly savings and less interest paid over time.
- Can make sense if you plan to own the home long enough to break even.
Cons:
- Requires more cash at closing.
- Less flexible if you plan to sell or refinance soon.
A quick rule of thumb: Break even equals cost of points divided by monthly savings. If the months to break even are longer than you plan to own the home, the points may not be worth it.
Who can fund a buydown?
- Buyer: You pay with your own funds at closing.
- Seller: Treated as a seller concession in resale deals. Must fit program limits.
- Builder: Often part of an incentive package on new construction. Incentives can be rate buydowns, closing-cost help, or upgrades.
- Lender credits: Lower your closing costs in exchange for a higher rate. This is the opposite of paying points.
For any buydown, the agreement and funding source should be documented in your closing disclosure and loan documents. Temporary buydowns include an escrow setup that details how and when funds are applied.
How lenders treat buydowns when qualifying
Most lenders qualify you using the full note rate. That means your debt-to-income ratio must still work at the regular payment after the temporary subsidy ends. Some lenders have different policies, but it is common to test your ability to handle the full payment and to require sufficient reserves.
Program rules and seller concession caps differ for conventional, FHA, VA, and USDA loans. Ask your lender to confirm whether a seller-funded buydown counts toward those caps and how it will appear on your Loan Estimate and APR disclosure.
How to compare scenarios
Use the same steps for any loan type so you can make an apples-to-apples decision.
- Gather inputs
- Loan amount and term. Use Encinitas-level numbers for realism.
- Note rate without a buydown. Get a live quote from your lender.
- For a permanent buydown: points and total cost.
- For a temporary buydown: the schedule, such as 2-1 or 1-0.
- Property taxes, homeowners insurance, and HOA dues if applicable.
- Any seller or builder credits and how they will be applied.
- Run the payment math
- Compute monthly principal and interest at the full note rate. This is your baseline.
- Compute monthly P&I at the reduced rate for each buydown year.
- Calculate monthly savings for each period.
- Check break even
- Permanent points: Divide total points cost by the monthly savings to get months to break even.
- Temporary buydown: Total the monthly savings during the temporary period and compare to the subsidy cost.
- Review APR and disclosures
- Ask your lender for a Loan Estimate showing the buydown, payment schedule by year, and APR. Confirm how funds will be documented on the Closing Disclosure.
- Confirm underwriting treatment
- Ask whether you will be qualified on the note rate or reduced payment, and whether reserves are required.
Hypothetical Encinitas-style example
This is a simple illustration using round numbers. Do not use these figures as current market quotes.
- Loan amount: 800,000
- 30-year fixed note rate without buydown: 6.50 percent
- Option A: Seller-paid 2-1 temporary buydown
- Option B: Permanent buydown via points
Baseline monthly P&I at 6.50 percent is about 5,060.
Option A, 2-1 buydown (temporary):
- Year 1 effective rate 4.50 percent. Monthly P&I about 4,054, so savings about 1,006 per month for 12 months.
- Year 2 effective rate 5.50 percent. Monthly P&I about 4,545, so savings about 515 per month for 12 months.
- Total savings to the buyer over two years is roughly 18,252. Compare that to the total subsidy cost funded at closing. If the subsidy cost is about 20,000, most of the benefit goes to easing the first two years, which can be valuable if cash flow is your priority.
Option B, permanent buydown with points:
- Suppose points reduce the rate to 6.00 percent. Monthly P&I would be about 4,796. Savings versus 6.50 percent is about 264 per month.
- If the points cost 12,000, break even is about 46 months. If you plan to own the home longer than that, permanent points may pay off. If you plan to sell or refinance sooner, they may not.
The right choice depends on your timeline and who funds the buydown. If a seller or builder funds a temporary buydown within program limits, you could keep more cash at closing and still get short-term relief. If you are paying out of pocket and plan to stay for many years, permanent points may create more lifetime savings.
Encinitas factors that change the math
High price points amplify dollars
Coastal San Diego price points mean one point or a one-time subsidy can be a large dollar amount. Always look at total dollars saved and break even, not just the percentage.
Taxes, insurance, and HOA dues
Buydowns do not affect property taxes, homeowners insurance, or HOA dues. In Encinitas neighborhoods with HOA-managed communities, those dues still factor into your total monthly payment and qualifying.
Seller concessions on resale homes
Whether a seller will fund a buydown depends on price, days on market, and competition. In faster segments, sellers may favor clean terms and higher net proceeds. In slower segments, a seller-funded buydown can help a buyer manage payments without a pure price cut. Ask your agent to check whether seller concessions are common for the specific neighborhood and listing.
Builder incentives on new homes
Builders often offer incentives such as rate buydowns, closing-cost help, or upgrades. Incentives might require using the builder’s preferred lender or staying within a specific timeline. Confirm in writing how the incentive is applied to the loan rate, price, or closing costs, and compare the net result to an alternative lender quote.
Timeline and rate locks
New construction can involve longer timelines. If you accept a temporary buydown or points, confirm your rate lock term and whether the incentive expires if closing is delayed.
Local program and documentation requirements
Down payment assistance or specialty programs may limit seller concessions or require specific buydown documentation. Ask your lender to confirm program rules, how funds are documented, and how the buydown appears on your disclosures.
What to ask your lender
Use these questions to get clear, written answers.
- How do you treat temporary buydowns for underwriting? Do you qualify me on the note rate or the reduced payment?
- Can you provide a Loan Estimate that shows the buydown funds, a year-by-year payment schedule, and the APR impact?
- Who is funding the buydown and how will it be documented on the Closing Disclosure?
- Will the buydown be held in a third-party escrow account? Who controls disbursements and what are the instructions?
- Do seller concession limits apply to this loan, and will this buydown count toward the cap?
- If I pay points, how many months to break even? Please show amortization with and without points.
- Does the buydown affect private mortgage insurance or FHA or VA mortgage insurance in any way?
- Are there lender overlays specific to San Diego County or to the loan amount that I should know about?
- Will taking a buydown change rate-lock terms or reduce lender credits I could otherwise receive?
- Do points or prepaid interest qualify as deductible mortgage interest for me, and should I ask a tax advisor?
What to ask the listing agent or builder
- Are seller-paid buydowns common or accepted for this property or builder?
- If the seller or builder funds a buydown, are there conditions like using a preferred lender or closing by a set date?
- Has the seller accepted buydowns on recent offers? What was typical?
- Are there other credits or price concessions available, and would the seller prefer a buydown instead of a price cut?
- For new construction, does the builder’s incentive change the base price or limit other concessions?
How to decide your next step
- If you want near-term payment relief and the seller or builder will fund it within program limits, a temporary buydown can make move-in months smoother.
- If you plan to stay put for years and you have cash available, permanent points may deliver better total savings.
- If closing costs are tight and payment relief is not a priority, a lender credit might be the simpler path.
The key is to put each option on one page and compare total cost, monthly payment over time, and break even. When the numbers are side by side, the best choice usually becomes clear.

FAQs
What is a 2-1 buydown on a mortgage?
- A 2-1 buydown temporarily reduces your effective rate by 2 percent in year one and 1 percent in year two, then your payment resets to your full note rate.
Do buydowns lower my taxes or HOA dues?
- No. Buydowns only reduce the interest portion of your principal and interest payment, not property taxes, homeowners insurance, or HOA dues.
Will a temporary buydown help me qualify for a loan?
- Often no, because many lenders qualify you using the full note rate rather than the reduced temporary payment, but you should confirm your lender’s policy.
Who usually pays for a buydown in Encinitas?
- Funds can come from you, the seller, or a builder. In resale deals, seller-funded buydowns count as concessions subject to program caps. Builders may include buydowns as incentives.
How do I know if points are worth it for me?
- Divide the cost of points by your projected monthly savings to get months to break even. If you plan to own longer than that, points may make sense.
Can I refinance if I used a temporary buydown?
- You can usually refinance if it fits your goals and lender requirements, but you should review timing, costs, and any incentive conditions with your lender before committing.
