Most ARMs require a 620 minimum credit score. Stronger scores unlock better initial rates and tighter margins at adjustment.
Lenders typically want a debt-to-income ratio under 45%. Your qualifying payment is based on the start rate, not the worst-case adjusted rate.
SRK CAPITAL shops ARMs across 200+ wholesale lenders. Not every lender prices ARM margins the same way — that spread matters at adjustment time.
Portfolio lenders sometimes offer ARM products with caps that retail banks won't touch. Access to that market is where a broker earns their fee.
A 5/1 ARM fixes your rate for five years, then adjusts annually. A 7/1 ARM buys you two more years of stability. Know your timeline before choosing.
The real risk isn't the adjustment — it's the cap structure. Lifetime caps of 5% are common. Run the worst-case payment before you sign.
A 30-year fixed gives you certainty. An ARM gives you a lower payment now. If you plan to sell or refinance within seven years, the ARM usually wins.
Jumbo ARM borrowers in Tustin often save significantly in the early years. That savings compounds when you invest the difference monthly.
Tustin Legacy and the Old Town corridor attract buyers who don't plan to stay 30 years. That makes ARMs a natural fit for this market.
Orange County's job market pulls in relocating professionals. Many buy with a 5-7 year horizon — exactly where an ARM outperforms a fixed loan.
After the fixed period ends, most ARMs adjust once per year. Your loan docs specify the exact schedule and index used.
Most conforming ARMs now use SOFR as the benchmark index. Your margin is added on top to set the new rate.
Caps limit how much your rate can move. A 2/2/5 cap means 2% at first adjustment, 2% per year after, 5% lifetime max.
If you're buying near or above conforming limits, the ARM savings are meaningful. Run the numbers against your hold timeline first.
Yes — and many Tustin borrowers do exactly that. Refinancing before the fixed period ends eliminates the adjustment risk entirely.
