County Median Income
Portfolio Arms typically require a 620+ FICO score and 5% to 20% down. Lenders look at your debt-to-income ratio — usually capped at 43% to 50%. The county's median household income of $126,240 gives you solid purchasing power in Dublin's market.
Your credit history matters more than a perfect score. Lenders review recent late payments, collections, and overall payment behavior.
Portfolio Arms are held by lenders on their own balance sheets, not sold to Fannie Mae or Freddie Mac. That means each lender sets its own rules. Rates and terms vary more than they do for conforming loans, so shopping around pays off.
Closing timelines run 30 to 45 days for Portfolio Arms. Underwriting is straightforward — lenders focus on credit, income, and assets. Brokers can access multiple lenders, which gives you more options than a single bank might offer.
Portfolio Arms make sense in Dublin if you're planning to move or refinance within five to seven years. The lower starting rate saves real money early on. Once the rate adjusts, your payment jumps — so a clear exit plan matters.
They don't pencil for buyers staying 15+ years. The rate adjustment risk outweighs the early savings. In Dublin's $800K to $1.1M range, a 30-year fixed often costs less over time than the total payment shock from a Portfolio ARM.
A 30-year fixed rate offers payment certainty — your rate and payment never change. Portfolio Arms start lower but adjust upward. The fixed-rate payment is higher at closing but predictable for 30 years.
Choose Portfolio Arms if you're confident you'll move or refinance before the adjustment. Choose fixed if you want to stay put and avoid payment surprises. Dublin's market supports both strategies — it depends on your timeline.

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.
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.
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.
