Ontario sits in the Inland Empire — one of California's busiest logistics and industrial corridors. That draws a mix of investors, self-employed borrowers, and business owners who don't fit standard loan boxes.

Portfolio ARMs are non-QM loans. Lenders keep them in-house instead of selling them. That means they set their own rules — and those rules are more flexible than conventional guidelines.
Expect lenders to want strong reserves, a reasonable debt-to-income ratio, and at least a 620–660 credit score. Some go lower depending on the deal.
Most banks don't advertise Portfolio ARMs. You won't find them on rate comparison sites. They live at community banks, credit unions, and portfolio-focused wholesale lenders.
SRK CAPITAL works with 200+ wholesale lenders. Several specialize in exactly this product. We know which ones price aggressively and which ones layer on conditions.
Most borrowers come to Portfolio ARMs because something blocks them from conventional financing. Unique income, recent credit events, or a property type that Fannie won't touch.
The ARM structure is often a feature, not a concession. If you're buying to flip, refi in 3 years, or bridge into a larger deal, paying for a 30-year fixed rate is waste.
DSCR loans use rental income to qualify. Portfolio ARMs can use any income type. That's a meaningful difference for borrowers with mixed income streams or primary residences.
Bank Statement loans share the non-QM space but are fixed-rate products. Portfolio ARMs offer the same flexible income approach with a lower starting rate — and an adjustment risk to manage.
Ontario's investor activity is real. Warehouse space, multi-unit rentals, and short-term rentals near Ontario International Airport all create demand for non-standard financing.
San Bernardino County has no local income limits or special restrictions on Portfolio ARMs. State lending laws apply, but nothing in the county adds friction to this loan type.
A regular ARM is sold to investors and follows strict guidelines. Portfolio ARMs stay with the lender, so terms are more flexible.
Yes. Portfolio lenders often accept rental income, business income, or bank statements. Requirements vary by lender.
Most adjust annually after an initial fixed period — often 3, 5, or 7 years. Your note will specify the index, margin, and caps.
Risk depends on your hold period. If you plan to sell or refinance before the first adjustment, rate risk is minimal.
Many lenders want 20–25% down on investment properties. Owner-occupied deals may allow less depending on the lender.
Yes — this is one of the best fits for self-employed borrowers. Lenders can use bank statements or P&L instead of tax returns.
