Question 1

What's the difference between a Portfolio ARM and a standard 30-year fixed mortgage?

Accepted Answer

A Portfolio ARM starts with a lower rate locked for 3, 5, 7, or 10 years. After that period, the rate adjusts annually or semi-annually. A 30-year fixed locks the same rate for the entire loan term.

Question 2

How much can my rate increase after the initial fixed period?

Accepted Answer

Most Portfolio ARMs cap total increases at 5% to 6% above your starting rate. Annual adjustments typically max out at 1% to 2% per year. Your lender will disclose the exact caps and adjustment schedule before closing.

Question 3

Do I need 20% down to qualify for a Portfolio ARM in Atherton?

Accepted Answer

No. Most lenders accept 5% to 10% down on Portfolio ARMs. Larger down payments improve your rate and reduce monthly payments, but they're not required. Lenders evaluate your credit, income, and reserves to determine the minimum down payment.

Question 4

What happens if interest rates spike after my fixed period ends?

Accepted Answer

Your rate adjusts upward, and your monthly payment increases. If rates rise significantly, refinancing to a fixed-rate loan becomes an option—though you'd pay closing costs again.

Question 5

Are Portfolio ARMs available for loans above the conforming limit?

Accepted Answer

Yes. Portfolio lenders often specialize in jumbo loans above the $1,249,125 conforming limit. Rates and terms vary by lender. Jumbo ARMs typically require 10% to 20% down and strong reserves, but they're available for Atherton's higher-priced homes.
