Found the Right Home? Smart Ways to Finance It: ARMs, 3-2-1 Buydowns and Interest-Only Loans

You finally walked into a home that checks the boxes. The layout works, the location works, and you can see yourself there. Then the mortgage rate conversation starts and the excitement fades a little.

Here is the good news: a 30-year fixed loan is not your only path. With good homes still moving quickly here on the Space Coast, it pays to know your financing options before you write an offer. Let's walk through three of them in plain English.

Why More Buyers Are Looking at Other Options

  • Adjustable-rate mortgages made up 11.4% of all mortgage applications in the most recent weekly report, the highest share since September 2025 (Mortgage Bankers Association data, reported by Homes.com, November 4, 2026).
  • The average 30-year fixed rate is still sitting above 7%, so buyers are looking for ways to lower their payment in the early years.
  • Waiting for rates to drop can mean competing with more buyers later. The right loan structure can help you move forward on the right home now.

Option 1: The Adjustable-Rate Mortgage (ARM)

An ARM gives you a fixed rate for a set number of years, usually at a lower rate than a 30-year fixed. After that, the rate can adjust with the market.

How it works

Intro fixed period: Commonly 5, 7, or 10 years. A "7/6 ARM" means the rate is fixed for 7 years, then can adjust every 6 months.

The new rate formula: When it adjusts, your rate equals a market benchmark (the "index") plus the lender's set amount (the "margin").

Built-in guardrails called caps:

    • Initial cap: limits how much the rate can change the first time it adjusts.
    • Periodic cap: limits each adjustment after that.
    • Lifetime cap: the highest the rate can ever go over the life of the loan.

Why it may make sense

  • Lower monthly payment during the fixed years.
  • If rates fall later, your payment can come down too.
  • A good match if you expect to sell, move, or refinance before the fixed period ends.

What to watch

  • Your payment can go up once the fixed period ends.
  • Know your caps and your "worst case" payment before you commit.
  • Refinancing later is never guaranteed. It depends on rates, your credit, and your home's value at that time.

Option 2: The 3-2-1 Buydown (Let the Seller Help)

This is one of my favorite tools to bring to the negotiating table. A 3-2-1 buydown temporarily lowers your interest rate for the first three years of a fixed-rate loan. The cost is paid upfront at closing, and very often it can be paid by the seller as a concession.

How it works

  • Year 1: Your rate is 3% below your actual loan rate.
  • Year 2: 2% below.
  • Year 3: 1% below.
  • Year 4 and beyond: You pay the full fixed rate for the rest of the loan. No surprises, no adjustments.

Why it can be a smart negotiating move

  • Instead of asking for a price reduction, we can ask the seller for a credit toward a buydown.
  • Sellers keep a stronger sale price, and you get real monthly savings right away.
  • In our example below, a seller credit of about $20,880 lowers the Year 1 payment by roughly $856 a month. That same amount taken off the price would lower the payment by only about $128 a month.
  • Prefer something shorter? A 2-1 buydown works the same way over two years and costs less.

What to watch

  • You must qualify at the full loan rate, not the reduced rate.
  • Seller credits have limits. On conventional loans it is generally 3% of the price with less than 10% down, 6% with 10% to 25% down, and 9% with more than 25% down. FHA allows up to 6% and VA up to 4%. Your lender will confirm what applies to you.
  • Plan your budget around the full payment that starts in Year 4.

Option 3: The Interest-Only Mortgage

This is a more specialized option. For a set period, your payment covers only the interest, not the loan balance.

How it works

  • Interest-only periods are available on some fixed and adjustable loans.
  • When the interest-only period ends, the loan switches to regular payments, which are higher because the balance is now paid off over fewer years.
  • Many loans allow you to pay extra toward the balance whenever you like.

Why it may make sense

  • The lowest payment of the three during the interest-only years.
  • Helpful when income varies from month to month, such as commission, bonus, or self-employment income. You can pay interest only in slower months and pay down the balance when the bonus or busy season comes.
  • Can free up cash for other investments or projects.

What to watch

  • You do not build equity through payments during the interest-only period.
  • The payment increase afterward can be significant.
  • It typically costs more over the full life of the loan.
  • Requirements are usually stricter, and not every lender offers it.

Side-by-Side Example

$500,000 purchase price, 10% down, $450,000 loan. Principal and interest only. Rates shown are for illustration only.

Loan Option Rate Monthly P&I Compared to 30-Yr Fixed
30-Year Fixed 7.25% $3,070 Baseline
7/6 ARM (years 1 to 7) 6.50% $2,844 Save about $225/mo (about $18,900 over 7 years)
3-2-1 Buydown Year 1 4.25% $2,214 Save about $856/mo
3-2-1 Buydown Year 2 5.25% $2,485 Save about $585/mo
3-2-1 Buydown Year 3 6.25% $2,771 Save about $299/mo
3-2-1 Buydown Year 4+ 7.25% $3,070 Same as fixed (seller-paid cost about $20,880)
Interest-Only (first 10 years) 7.25% $2,719 Save about $351/mo, then rises to about $3,557 in year 11

Taxes, insurance, HOA, and mortgage insurance are not included. Your actual rate and payment will depend on your credit, down payment, loan type, and the market on the day you lock.

Which Option Fits You?

  • Planning to sell or move within 5 to 10 years? An ARM may be worth a look.
  • Want the security of a fixed rate with breathing room up front? Ask about a seller-paid 3-2-1 or 2-1 buydown.
  • Have income that varies through the year? An interest-only loan could be a conversation to have with your lender.
  • Want one payment that never changes? The 30-year fixed is still a great choice, and you can refinance later if rates improve.

The Bottom Line

A higher rate does not have to mean missing out on the right home. The key is having a plan before we write the offer, so we know exactly what to ask the seller for and which loan fits your goals.
