How Much House Can You Afford in Santa Clarita?

Most people ask this question backward. They pick a house, then hope the payment works. Do it the other way. Figure out the monthly payment you can carry without choking, then shop for the house that fits it. Here is how that math actually runs in Santa Clarita in 2026, with the local costs that wreck a lot of budgets left in.

Start with the 28/36 rule

This is the oldest affordability test for a reason. It works. Two numbers.

• 28 percent: your total monthly housing payment should sit at or under 28 percent of your gross monthly income. Housing means the whole payment, not just the loan.
• 36 percent: all your monthly debt combined, housing plus car payments, student loans, credit card minimums, should sit at or under 36 percent of gross income.

Say you earn $180,000 a year. That is $15,000 a month gross. The 28 percent line puts your housing ceiling near $4,200 a month. The 36 percent line caps total debt near $5,400. If you already pay $900 a month on cars and loans, your housing room shrinks to about $4,500 on the back end, and the 28 percent front-end number becomes your real limit. The lower of the two numbers wins. Lenders run a stricter version of this same test when they approve you.

Build the real Santa Clarita payment

Here is where people get burned. The mortgage is only one piece. A real Santa Clarita payment has four or five parts, and the last two are local.

• Principal and interest: the loan itself. On a $600,000 loan, this is the biggest line by far.
• Property tax: figure roughly 1.1 to 1.25 percent of the purchase price per year in Los Angeles County. On a $750,000 home that is around $700 to $780 a month.
• Homeowners insurance: budget $120 to $250 a month, more if the home backs to brush or a high fire zone, which matters in parts of Canyon Country and Castaic.
• Mello-Roos: a special tax on many newer tracts. Can run $150 to $400-plus a month on top of regular property tax.
• HOA dues: common in gated and newer communities. Often $100 to $300 a month, sometimes more with extra amenities.

Add it up on a $750,000 home with 20 percent down. The loan is $600,000. Principal and interest, tax near 1.1 to 1.25 percent, insurance, and on a newer tract Mello-Roos plus HOA, can push the all-in monthly payment well past $5,000. The same price in an older Saugus or Canyon Country tract with no Mello-Roos and no HOA can land several hundred dollars a month lower. Same sticker price. Very different real cost.

The down payment you actually need

You do not need 20 percent. That myth keeps good buyers renting for years. Here are the real floors.

• FHA: as low as 3.5 percent down. On a $750,000 home that is $26,250, though FHA loan limits and mortgage insurance apply.
• Conventional: many programs start at 3 to 5 percent down. Five percent on $750,000 is $37,500.
• 20 percent: $150,000 on a $750,000 home. This is what kills private mortgage insurance and gets you the cleanest payment.

The trade-off is simple. Less money down means a bigger loan, mortgage insurance until you build equity, and a higher monthly payment. More down means a smaller payment and more room under your 28 percent line. There is no single right answer. There is only the answer that fits your cash and your monthly budget.

What median income buys across the valley

The SCV is not one price. Where you shop changes how far your budget stretches.

• Valencia and Stevenson Ranch: usually at or above the median, with more Mello-Roos and HOA in the newer gated tracts. Budget for higher carrying costs.
• Saugus: a strong middle. Many of the same schools as Valencia, often a touch friendlier on price. See living in Saugus.
• Canyon Country and Newhall: often the best entry points in the valley. More older tracts without Mello-Roos, which can mean a lower real monthly payment at the same loan size.
• Castaic: can offer more square footage for the money, with the trade-off of a longer drive up the I-5.

Stress-test the number before you commit

The 28/36 rule is a ceiling, not a target. Just because a lender approves you for $5,000 a month does not mean you should spend it. Run a tougher version on yourself.

Can you still save? If the payment leaves nothing for retirement or an emergency fund, you bought too much house. Does it survive one income hiccup? If a single slow month or a job change would put you behind, drop your price range. Did you count the extras? A new home in the SCV summer means real air conditioning bills in July and August when it sits in the high 90s to low 100s. Furniture, repairs, and higher utilities are real. Leave room.
