Portfolio ARMs are offered by portfolio lenders — banks that hold loans on their own books rather than selling to Fannie Mae or Freddie Mac. This means underwriting overlays are tighter but terms are more flexible.
California portfolio lenders typically close ARMs in 21–30 days. Appraisals and title work move at standard pace. The ARM market is smaller than conventional, so fewer lenders compete — that's why direct broker relationships matter.
Portfolio ARMs make sense in Paso Robles for buyers with a clear exit plan. If you're buying a rental or a second home you'll sell in five years, the ARM's lower initial rate saves real money.
The math shifts above $800,000. Jumbo ARMs carry wider rate spreads and require 20% down. At that price, the fixed-rate jumbo often pencils better because the rate premium is smaller than the ARM's adjustment risk over a decade.
A 30-year fixed-rate mortgage locks your payment for life. A Portfolio ARM starts lower but adjusts after the initial period. Fixed means predictability; ARM means lower early payments if you're selling or refinancing soon.
Fixed-rate borrowers sleep easier — no rate shock risk. ARM borrowers get lower initial payments and can refinance before adjustment. Choose fixed if you're staying long-term; choose ARM if your timeline is short and you want to minimize early payments.
The SLO Land Conservancy just secured 750 acres for the Morro Bay-to-Cayucos connector trail. That $5.5 million transaction signals county commitment to outdoor access and recreation infrastructure.
San Luis Obispo also opened Righetti Hill open space on the city's south side, adding public hiking access. These projects matter to buyers who want outdoor recreation without a long drive.
Portfolio ARMs are held by the lender, not sold to Fannie Mae. That means tighter underwriting but more flexible terms. Rate caps and adjustment schedules vary by lender — ask for the full disclosure before locking.
It depends on the product. A 5/1 ARM stays fixed for five years, then adjusts annually. A 7/1 ARM fixes for seven years. The adjustment cap limits how much the rate can jump per year and over the loan's life. Ask your lender for the specific caps.
Only if you plan to move or refinance within 5–7 years. If you're staying long-term, a fixed-rate mortgage removes refinance risk and keeps your payment stable. ARMs work best for buyers with a clear exit plan.
Minimum 10% down for most products. 15–20% down improves your rate and terms. Jumbo ARMs above $1,000,500 require 20% down and stronger reserves. The more you put down, the better your pricing.
Yes. Many ARM borrowers refinance into a fixed rate before adjustment kicks in. If rates drop or your credit improves, refinancing is an option. Plan ahead — refinancing costs time and money, so lock in a fixed rate early if you're concerned.
