Portfolio ARMs in Seaside
Portfolio ARMs require 620+ FICO and typically 10–20% down, though some lenders go lower with compensating factors. The initial rate lock runs 3, 5, 7, or 10 years depending on the product you choose.
Lenders underwrite Portfolio ARMs to the fully-indexed rate — the rate you'd pay if adjustments happened immediately. That's stricter than fixed-rate underwriting and means your debt-to-income ratio must stay tight. Plan on 43% DTI or lower for approval.

Seaside sits at the heart of Monterey County's ag-tech boom. Reservoir Farms just opened a 24-acre innovation hub in nearby Salinas with 12 specialty crop robotics startups.

Portfolio ARMs require 620+ FICO and typically 10–20% down, though some lenders go lower with compensating factors. The initial rate lock runs 3, 5, 7, or 10 years depending on the product you choose.
Portfolio ARMs are held by lenders' own balance sheets, not sold to Fannie Mae or Freddie Mac. That means fewer lenders offer them and pricing varies widely. Brokers can shop multiple portfolio lenders to find the best rate and terms for your scenario.
Expect 45–60 day closes on Portfolio ARMs. Underwriting is thorough because the lender keeps the loan. Documentation requirements match or exceed conforming standards. Call for a rate quote and lock period options — those details shift with market conditions.
Portfolio ARMs make sense in Seaside if you're buying at $550,000–$700,000 and plan to sell or refinance within five years. The rate savings in year one are real. After year five, the payment jumps and you need an exit strategy.
They don't pencil for buyers who plan to stay 10+ years. The cumulative payment shock after adjustments erase the early savings. If you're buying your forever home in Seaside, a fixed rate is safer even if it costs 0.5% more upfront.
A 30-year fixed mortgage locks your payment forever. Portfolio ARMs start lower but adjust upward after year five. Fixed rates run 0.5–1% higher at origination but eliminate refinance risk and payment shock.
Choose fixed if you're staying in Seaside long-term or if rate uncertainty stresses you. Choose ARM if you're confident you'll sell or refinance before adjustments kick in and you want the lowest possible starting payment.
Navigator Charter Schools is launching three TK-12 campuses across Monterey County in 2026-27, including one in Marina/Seaside. New school options matter for families and can shift where buyers choose to settle.
The Monterey County Board of Supervisors approved $9.5 million in road, park, and public-safety projects funded by Measure AA. Better roads and parks make Seaside more attractive to buyers and renters alike.
The first number is the lock period. 5/1 means your rate stays fixed for five years, then adjusts annually. 7/1 locks for seven years. Longer locks cost more upfront but delay payment shock. Choose based on when you plan to sell or refinance.
Yes. You can refinance anytime, but you'll pay closing costs again. If rates drop, refinancing makes sense. If rates rise, you're stuck with the ARM unless you want to absorb the cost. Plan your exit strategy before you sign.
That depends on the index, margin, and how much rates have risen. A typical adjustment might add $100–$300 per month on a $600,000 loan. Worst-case caps exist (usually 2% per year, 6% lifetime), but they're still painful.
Only if you're certain you'll move or refinance within five years. First-time buyers often stay longer than they expect. A fixed rate costs more upfront but protects you if life changes and you stay in Seaside longer than planned.
Most lenders require 620+ FICO. Some go lower with compensating factors like large down payment or strong reserves. Call for a pre-qualification. Your exact score, income, and assets determine what you qualify for.
