Looking for a way to lower your monthly payment without putting your Aliso Viejo plans on hold? You are not alone. Many buyers are weighing temporary buydowns against adjustable-rate mortgages to create breathing room in the first few years. In this guide, you’ll learn how each option works, what it really costs, and how to choose the structure that fits your timeline and cash flow. Let’s dive in.
Buydowns and ARMs explained
What a temporary buydown is
A temporary buydown lowers your mortgage payment for the first few years by reducing the rate used to calculate your payment. Common versions include 2-1 and 3-2-1 buydowns.
- 2-1 buydown: Year 1 is the note rate minus 2%, Year 2 is the note rate minus 1%, and Year 3 and beyond revert to the full note rate.
- 3-2-1 buydown: Year 1 is minus 3%, Year 2 minus 2%, Year 3 minus 1%, and Year 4 and beyond revert to the note rate.
- Who pays: The buydown is funded up front by you, the seller or builder as a concession, or sometimes the lender. The lender escrows the funds and applies them to lower your required payment in those early years.
- Your note rate does not change. Only your required payment does during the buydown period.
What an ARM is
An adjustable-rate mortgage has a fixed period, then adjusts on a set schedule. Common products include 5/1, 7/1, and 10/1.
- Initial rate: ARMs usually start with a lower rate than a comparable 30-year fixed during the initial fixed period.
- After the fixed period: Your rate equals an index plus a margin set by the lender. Indexes vary over time. Margins are fixed in your loan terms.
- Caps: ARMs include limits on how much the rate can move at the first adjustment, at each subsequent adjustment, and over the life of the loan. A 2/2/5 cap means a 2% maximum change at the first adjustment, 2% per year after, and a 5% lifetime increase over the start rate.
- Qualification: Some lenders qualify you using the fully indexed ARM rate or a set qualifying rate, which can affect your debt-to-income ratio.
What matters in Aliso Viejo
Aliso Viejo sits in Orange County, where many homes and condos fall in the mid to high six figures and into seven figures. That means loan size and program choice can influence whether a buydown or an ARM is more attractive.
- Conforming vs. jumbo: County loan limits change over time. Check current limits to know when jumbo pricing applies, since jumbo margins and pricing can change the math.
- Property taxes: California’s base property tax rate is about 1% of assessed value, plus local assessments and any Mello-Roos. Include these, not just principal and interest, in your affordability.
- HOAs and insurance: Many Aliso Viejo properties have HOA dues. Coastal-area insurance can be higher than national averages. Add both to your monthly budget.
- Seller incentives: In certain market conditions or with new construction, sellers and builders sometimes fund buydowns as a concession. If available, this can make a buydown very cost-effective.
Illustrative payment examples
Below is a simple example to show how payments can differ. These figures are illustrative only. Get current pricing from your lender before you decide.
- Purchase price: $1,200,000
- Down payment: 20%
- Loan amount: $960,000
- Illustrative 30-year fixed note rate: 7.00%
At 7.00%, principal and interest is about $6,386.90 per month.
2-1 buydown on a 7.00% note
- Year 1 payment at 5.00%: about $5,156.69
- Year 2 payment at 6.00%: about $5,755.68
- Year 3 and beyond: about $6,386.90
- Upfront subsidy required: roughly $22,337 total for the first two years, about 2.33% of the loan amount
3-2-1 buydown on a 7.00% note
- Year 1 at 4.00%: about $4,586.79
- Year 2 at 5.00%: about $5,156.69
- Year 3 at 6.00%: about $5,755.68
- Year 4 and beyond: about $6,386.90
- Upfront subsidy required: roughly $43,938 for three years, about 4.58% of the loan amount
5/1 ARM example
- Hypothetical initial rate: 6.00%
- Payment for first 5 years: about $5,755.68
- After year 5: Adjusts to index plus margin, subject to caps such as 2/2/5
What this shows:
- A 2-1 buydown often costs much less upfront than a 3-2-1 but still creates meaningful relief in the first two years.
- An ARM can deliver a payment similar to a buydown during the fixed period, but your rate and payment can rise after the first adjustment.
- Buydowns deliver predictable, temporary relief. ARMs deliver lower initial rates with future uncertainty.
Buydown vs ARM: how to choose
Time horizon and exit plan
If you expect to sell or refinance within 3 to 5 years, both a temporary buydown and a shorter ARM can work. Compare the total buydown cost with the expected ARM savings over the same period.
If you expect to stay 7 or more years, a full fixed rate often reduces interest risk. You can still use a buydown on a fixed loan if near-term payment relief is helpful and you can fund it or negotiate it from the seller.
Cash available and seller help
If you can pay points, a buydown lets you trade upfront cash for lower early payments. When a seller funds the buydown as a concession, it can be very attractive because it preserves your own cash.
Ask your lender to confirm whether the buydown will be treated as a seller concession and how that affects the offer. In some cases, concession limits and appraisals can come into play.
Qualifying and DTI
Some lenders qualify ARMs using the fully indexed rate, which can reduce your maximum loan amount. Ask how your lender will qualify you for both options. Also confirm whether the reduced buydown payment can be used for qualification or if they will use the note rate.
Rate outlook and risk tolerance
If you believe rates may fall and you plan to refinance, an ARM might fit. If you are concerned about payment changes, a buydown on a fixed-rate loan gives you a predictable path after the buydown period.
Program and loan size
Jumbo loans can price differently and may change the relative value of an ARM versus a buydown. FHA and VA programs have rules for concessions and buydowns. Confirm feasibility with your lender for your exact loan type.
Taxes and deductions
Buyer-paid points and seller-paid concessions can be treated differently for tax purposes. If you are paying significant points or receiving a large concession, talk with a tax-aware advisor.
How to compare offers step by step
Use this checklist to get apples-to-apples comparisons from your lender. Ask for items in writing.
- Loan Estimate and costs
- Request a Loan Estimate showing who funds the buydown and the exact dollar amount. Confirm if it counts as a seller concession.
- Amortization schedules
- Get a full amortization schedule for the fixed loan with the buydown, showing the reduced payments in buydown years and the payment at the note rate afterward.
- ARM disclosures
- For each ARM option, ask for the index used, the margin, the adjustment caps (initial/periodic/lifetime), and the fully indexed rate used to qualify you.
- Underwriting rules
- Confirm whether the lender qualifies you on the reduced buydown payment or the note rate, and for ARMs, whether they use a fully indexed rate or other qualifying standard.
- Escrow mechanics
- Ask how buydown funds are held and applied. Some programs escrow the funds, and some deduct from seller proceeds at closing.
- Offer strategy
- For seller-funded buydowns, review how the concession affects the seller’s net, any concession limits, appraisal considerations, and offer competitiveness in the Aliso Viejo market.
Tax-aware moments to call a pro
Consider consulting a tax-aware financial advisor or CPA when any of the following apply:
- The seller funds a buydown or provides significant concessions and you want to understand deductibility or basis impact.
- You plan to itemize deductions and want clarity on immediate versus amortized deductibility of points.
- You are self-employed or have complex income timing and need to coordinate mortgage interest with your estimated taxes.
- You are considering short-term rental, second home, or investment use.
- You want to confirm how California-specific rules could affect your tax picture.
Bring your settlement statement and buydown documents so your advisor can review the exact terms.
Quick pros and cons
Temporary buydown
- Pros: Predictable payment relief for defined years; can be funded by seller; useful bridge if income is rising or you expect to refinance.
- Cons: Requires upfront funds; after the buydown period, the payment resets to the note rate; if you pay the buydown yourself, consider the opportunity cost of that cash.
ARM
- Pros: Lower initial rate during fixed period; may reduce payments for 5 to 10 years depending on the product.
- Cons: Payment can increase after the fixed period; qualification may use a higher assumed rate; caps limit but do not eliminate future payment risk.
Common buyer profiles
- First-time or upgrading buyers with a 5 to 7 year horizon: A 2-1 buydown or a 5/1 or 7/1 ARM can fit if you expect to move or refinance.
- Move-up buyers planning to stay longer: Consider a fixed rate. A buydown can ease the first years, while you retain long-term payment certainty.
- New construction buyers: If a builder offers a seller-funded buydown, it can be a cost-effective way to lower early payments.
Put it together: sample decisions
You plan to live in the home for 4 to 5 years and expect to refinance once rates improve. A 5/1 ARM or a 2-1 buydown on a fixed loan both deliver similar early payments. Compare the total buydown cost with the ARM’s savings over five years, and decide whether you prefer predictable fixed-rate security after year two or the lower ARM rate during years one through five.
You plan to stay 10 years or more. A fixed rate with or without a buydown reduces long-run risk. If a seller will fund a 2-1 buydown, you can enjoy lower payments for two years and lock in predictability thereafter.
