Adjustable-Rate Mortgages (ARMs) in Jacksonville: A Plain-English 2026 Guide

When 30-year fixed rates are high, more buyers ask about adjustable-rate mortgages. Some remember the risky loans from before 2008 and steer clear. Today’s ARMs work very differently. Here’s a plain-English guide from North Star Mortgage Network, a Jacksonville mortgage broker serving Florida since 2000.

How a Modern ARM Works

1. A fixed period. Your rate is locked for 5, 7 or 10 years and can’t change during that time.
2. A published index. After the fixed period, the rate adjusts based on a public market index, most often SOFR, plus a set margin.
3. Caps. Caps limit how much the rate can rise at the first adjustment, at each adjustment after that, and over the life of the loan. They’re disclosed before you close, so your worst case is known from day one.
4. No prepayment penalty on most ARMs. You can refinance into a fixed rate later if it makes sense, subject to credit approval.

Common ARM Types

ARM	Fixed for	Then adjusts
5/6 ARM	5 years	Every 6 months
7/6 ARM	7 years	Every 6 months
10/6 ARM	10 years	Every 6 months
FHA and VA ARMs	Often 5 years or more	Usually yearly, often with tighter caps

Available for qualified borrowers. Program guidelines apply. FHA and VA guidelines may change; lender overlays may be stricter.

A Simple Example

Hypothetical rates for illustration only, not a quote. Estimate based on the information provided.

On a $400,000 loan, compare a 30-year fixed at 7.00% with a 5/6 ARM starting at 6.25%:

• 30-year fixed: about $2,661 a month in principal and interest
• 5/6 ARM: about $2,463 a month for the first five years
• Difference: about $198 a month, or roughly $11,900 over five years

Now the worst case

Suppose that ARM has caps of 2% at the first adjustment, 1% after that, and 5% over the life of the loan. If rates rose as much as allowed, the rate in year six could be no higher than 8.25%. On the remaining balance of about $373,000, the payment would be about $2,944, roughly $282 more a month than the fixed loan. The rate could keep rising later, but never above 11.25% under those caps.

That’s the honest trade: lower payments now, in exchange for the chance of higher payments later. Caps vary by loan, and we’ll show you the exact caps on any ARM before you decide.

Who an ARM Can Make Sense For

• Military families: if you’re likely to PCS within a few years, a VA ARM can lower your payment while you’re here. See our VA loans in Jacksonville guide.
• Buyers who expect to move: a starter home you plan to sell in 5 to 7 years.
• Buyers who plan to refinance: if rates fall, you can refinance into a fixed loan, subject to credit approval.
• Buyers expecting income growth who want a lower payment now and understand the risk.

Who Should Probably Choose a Fixed Rate

• You plan to stay in the home long term and want a payment that never changes
• Your budget couldn’t absorb the worst-case payment
• A changing payment would keep you up at night

ARM vs Buydown vs Fixed

An ARM isn’t the only way to lower your starting payment. A temporary buydown lowers the rate for the first year or two, often paid by the seller. See our guides to the 2-1 buydown and temporary vs permanent buydowns.

Why Compare With a Broker

ARM pricing, margins and caps vary a lot from lender to lender. As an independent broker, North Star compares fixed and adjustable options from many wholesale lenders side by side, on the same day, for your exact loan. You see the numbers, including the worst case, and you choose.

Frequently Asked Questions

Is an ARM risky?

An ARM’s rate is fixed for the first 5, 7 or 10 years, then can change within caps that are set in writing before you close. The risk is that the rate goes up after the fixed period. The caps tell you the most it can rise, so you can plan for the worst case from day one.

What do 5/6, 7/6 and 10/6 mean?

The first number is how many years the rate stays fixed. The 6 means the rate can adjust every six months after that. Many ARMs today adjust based on SOFR, a published market index.

Can I refinance out of an ARM?

Usually yes. Most ARMs have no prepayment penalty, so you can refinance into a fixed rate if rates drop or your plans change. Refinancing is subject to credit approval and market conditions at that time.

Are there FHA and VA ARMs?

Yes. FHA and VA both offer adjustable-rate options, and they often have tighter caps than conventional ARMs. FHA and VA guidelines may change; lender overlays may be stricter.

Who is an ARM a good fit for?

Buyers who expect to move or refinance within the fixed period, such as military families on orders, professionals expecting relocation, or buyers who want a lower starting payment and understand the adjustment risk.

How do lenders qualify me for an ARM?

Lenders often qualify ARM borrowers at a rate higher than the starting rate, so you can handle a possible increase. The exact rule depends on the loan program.
