Chino Hills · just over the hill from Yorba Linda
Mortgage Broker in Chino Hills, CA
Chino Hills looks like Orange County and feels like Orange County. For lending, it isn't. Here's what changes when you cross the county line.
NMLS #487617Licensed in 32 statesChino Hills
When I head to Chino Hills, I take Carbon Canyon Road. It's State Route 142, it winds up and over the hill from the Brea and Yorba Linda side, and on a clear day you forget you're fifteen minutes from a freeway. Then you come down the other side into Chino Hills, and a few things are different. The county is one of them.
I'm Brian Poetschlag, a mortgage broker at West Capital Lending. I live in Yorba Linda and I've been in the mortgage business since 2002. When people search for a mortgage broker in Chino Hills, they're often surprised that their Orange County numbers don't carry over. Let me show you why.
The county line changes your loan
Chino Hills sits in San Bernardino County. Its neighbors to the west and south, Brea and Yorba Linda, sit in Orange County. That line matters more than it looks on a map.
Loan limits are set by county. Orange County gets a high-balance limit of $1,249,125 for a one-unit home in 2026. San Bernardino County uses the national baseline, $832,750.
Here's what that looks like. Illustration only:
- A family refinancing a $950,000 balance on a house in Yorba Linda is inside the conforming high-balance limit.
- The same $950,000 balance on a house a few miles over the hill in Chino Hills is a jumbo loan.
Jumbo isn't bad. Sometimes jumbo pricing is competitive with conforming. But the rules change: different down payment minimums, more reserves, and stricter treatment of some income. If your loan amount lands anywhere between $832,750 and $1,249,125, the county line decides which set of rules you're playing by. I price both sides so you can see where the break falls.
Property taxes go through San Bernardino County
Your property tax, and the supplemental bill that shows up after you buy, come from San Bernardino County. The rules follow the same state law as Orange County, but the office, the timing and the bill are different.
The supplemental bill catches a lot of new owners off guard. It covers the gap between the old owner's assessed value and your purchase price, and it's often not paid out of your escrow account. Set that money aside.
A young city of planned neighborhoods
Chino Hills incorporated in 1991. Much of the city was built out in the decades around that, in master-planned tracts with parks, trails and HOAs. Butterfield Ranch, in the southern part of the city, is a good example. Los Serranos, around the golf course on the eastern side, is one of the older areas and has a different feel. Gated communities like Vellano sit up in the hills.
Newer tracts often come with Community Facilities District taxes, better known as Mello-Roos, plus HOA dues. Lenders add both into your monthly housing payment. On a purchase, that can cut your buying power more than a small change in price would. I want the Mello-Roos and HOA figures for any house you're serious about before you write an offer.
Why buyers come for the schools and the space
A lot of buyers I talk to come to Chino Hills for Chino Valley Unified schools. The district has a strong reputation and families plan around it.
The other draw is space. Chino Hills State Park covers a big stretch of open hills along the city's southern and western edge, with trails that reach toward Yorba Linda and Brea. You can live in a neighborhood with good schools and still see open ridgelines from the kitchen.
For buyers, that combination means competition. My home purchase loans page covers how I set up a purchase, from full underwriting before you shop to comparing jumbo and conforming options on the same house.
HELOC in Chino Hills
Plenty of Chino Hills owners bought in the 1990s and 2000s. They refinanced when rates were low, and now they sit on a low first mortgage and a lot of equity. A HELOC is usually the cleanest way to use that equity. It's a second lien, so your first mortgage stays exactly where it is.
What Chino Hills owners use it for:
- A backyard remodel, pool or ADU.
- College costs, since a lot of the kids from those 1990s tracts are college age now.
- Paying off a car loan or credit cards at a higher cost.
- A down payment on a rental or a second home.
One thing to know: HELOC lenders each set their own maximum combined loan-to-value, so the line one lender offers can be a lot bigger than another's. Credit unions in the area each offer one product. I compare lines from 175+ lenders and show you the side-by-side with the APR on each.
Quick math. Every 1 percentage point on $100,000 is about $83 a month in interest. On a $120,000 line, a one-point difference is about $100 a month. More detail on the HELOC page.
When a refinance makes more sense
A HELOC isn't always the answer. If your first mortgage is a jumbo from a few years back, or you want to drop PMI, or you have an ARM coming due, a refinance may be the better move. In Chino Hills, a refinance can also change your loan category. If you've paid your balance down below $832,750, an old jumbo can become a conforming loan. I run both paths so you can compare.
Every loan I offer, for Chino Hills
Families buying here usually start with a purchase loan. Long-time owners start with a HELOC or a refinance. Owners 62 and older sometimes want to talk through a reverse mortgage. Here's all eight.

Questions people ask
What's the conforming loan limit in Chino Hills?
Chino Hills is in San Bernardino County, which uses the 2026 baseline conforming limit of $832,750 for a one-unit home. Orange County's high-balance limit is $1,249,125. A loan above $832,750 in Chino Hills is a jumbo loan.
Does Mello-Roos affect how much house I can buy in Chino Hills?
Yes. Lenders count Mello-Roos special taxes and HOA dues as part of your monthly housing payment. Two homes at the same price can qualify very differently depending on those bills, so I look them up before you write an offer.
Who sends my supplemental property tax bill in Chino Hills?
San Bernardino County, not Orange County. After you buy, expect a supplemental bill based on the new assessed value. It's often not paid through your escrow account, so set the money aside.
