Novato sits at the northern edge of Marin County — one of California's most expensive markets. Properties here routinely price out conventional loan limits.
HousingWire flagged ARM demand shifting as the 30-year fixed hit 6.57%. That shift matters for Novato buyers where a lower initial rate can change deal math significantly.

Portfolio ARMs are non-QM loans. Lenders set their own rules — so credit requirements, income documentation, and reserves vary by lender.
Most portfolio lenders want strong compensating factors. Think 12+ months reserves, solid assets, or a clear repayment story beyond a pay stub.
Portfolio lenders keep these loans on their own books. That means they can bend guidelines that Fannie Mae or Freddie Mac won't allow.
Not every lender offers portfolio ARMs. Access to 200+ wholesale lenders means we can find programs that most retail banks never show you.
I see these loans work best for high-income borrowers with complex financials. W-2 earners with simple returns rarely need them.
Watch the adjustment caps and index carefully. A 5/1 ARM tied to SOFR behaves differently from one tied to a lender's internal rate.
A standard ARM gets sold to the secondary market. A portfolio ARM stays with the lender — which gives them room to customize terms for your situation.
DSCR loans and Bank Statement loans solve similar problems for investors. But portfolio ARMs can work for primary residences too, which those programs often won't.
Novato attracts buyers moving north out of San Francisco and San Rafael. Many are business owners or equity-rich sellers — exactly who portfolio ARMs are built for.
Marin's property values create jumbo loan territory fast. A portfolio ARM with a lower initial rate can reduce payment pressure in the early years of ownership.
Business owners, self-employed buyers, and high-net-worth borrowers with complex financials. Standard loan programs often can't capture their full financial picture.
The lender keeps it on their own books instead of selling it. That lets them set custom terms, flexible income docs, and non-standard structures.
Yes. They don't follow Fannie Mae or Freddie Mac guidelines. Qualification rules are set entirely by the portfolio lender.
Ask about the initial cap, periodic cap, and lifetime cap. These control how much your rate can move at each adjustment period.
Yes — unlike DSCR loans, portfolio ARMs can be used for primary residences. That makes them a broader tool for Marin County buyers.
Requirements vary by lender, but 12 months of reserves is a common baseline. Strong reserves can offset other risk factors in your file.
