Question 1

What happens to my payment when the Portfolio ARM rate adjusts?

Accepted Answer

Your payment increases based on the new rate. The adjustment cap limits how much the rate can rise per adjustment period. Review the adjustment schedule before signing — know your worst-case payment.

Question 2

Can I refinance before the rate adjusts?

Accepted Answer

Yes. Refinancing is your escape route if rates drop or your situation changes. Plan for refinancing costs — typically 2% to 5% of the loan amount. If you're staying five years, refinancing is realistic.

Question 3

Do I need 20% down for a Portfolio ARM in Dublin?

Accepted Answer

No. Portfolio Arms accept 5% down, though 10% to 15% improves your rate. Less down means a higher rate, but you keep more cash at closing. The tradeoff is yours to make.

Question 4

How does the county's median income affect my qualification?

Accepted Answer

Alameda County's median household income is $126,240. Lenders use this to assess area affordability. Your personal income must support your debt-to-income ratio, typically capped at 43% to 50%.

Question 5

Is a Portfolio ARM right for Dublin buyers?

Accepted Answer

Yes, if you're selling or refinancing within five to seven years. The lower starting rate saves money early. If you're staying 10+ years, a fixed rate usually costs less overall.
