Question 1

What makes a portfolio ARM different from a regular ARM?

Accepted Answer

The lender keeps the loan instead of selling it. That means they set their own terms and can approve profiles that don't fit agency guidelines.

Question 2

How long does the initial fixed rate period last?

Accepted Answer

Most portfolio ARMs offer 5, 7, or 10-year fixed periods. After that, the rate adjusts based on a set index plus a margin.

Question 3

Is a portfolio ARM a non-QM loan?

Accepted Answer

Yes. Portfolio ARMs don't follow Qualified Mortgage rules. That flexibility is the point — it opens doors standard loans close.

Question 4

Can I use a portfolio ARM to buy in San Anselmo above conforming limits?

Accepted Answer

Yes. Portfolio lenders aren't bound by conforming loan limits. That makes them viable for high-value Marin purchases.

Question 5

What credit score do I need for a portfolio ARM?

Accepted Answer

Most portfolio lenders want 680 or higher. Strong reserves and a clear exit strategy can support approval near that floor.

Question 6

How do I know if an ARM makes sense for my timeline?

Accepted Answer

If you plan to sell or refinance within the fixed period, an ARM usually saves money. We run the numbers based on your actual hold plan.
