How Much Home Can We Afford When We Move Up in Orange County?

How much home can your family afford when you move up in Orange County? The answer comes from what your current home will net you, what a lender will approve, and the payment you want to live with, in that order.

I'm Jeanette Nelson, a REALTOR® with Jeanette Nelson Real Estate, Keller Williams Realty, serving Orange County, Huntington Beach, Costa Mesa, Fountain Valley, and surrounding areas. Move-up families often have more buying power than they expect, because of the equity they've built. They also have more moving parts, so it helps to see the whole picture before you list.

For context, in my July 2026 market snapshot, the average single-family sale price was $1,902,980 in Huntington Beach, $1,950,488 in Costa Mesa and $1,499,325 in Fountain Valley. Those are averages across many kinds of homes, so your own price range depends on the neighborhood and the home.

This is your net proceeds, and it often becomes most of your next down payment. A simple way to estimate it:

1. Start with a realistic sale price based on recent like-kind sales near you.
2. Subtract your loan payoff, plus any home equity line.
3. Subtract selling costs, such as commissions if applicable, escrow, title, transfer tax and any repairs or credits.
4. Set aside money for taxes, if any part of your gain may be taxable.

What's left is the cash you can put toward the next home, moving costs and a cushion.

Many families won't, or will owe less than they fear. The IRS lets you exclude up to $250,000 of gain on the sale of your main home, or $500,000 for a married couple filing jointly. You generally must have owned and lived in the home for at least two of the last five years, and you can use the exclusion only once in a two-year period.

The California Franchise Tax Board follows the federal rules on this exclusion. If your gain is larger, or you rented the home at some point, talk with a CPA before you list. This is general information, not tax advice.

Lenders look at your debt-to-income ratio, or DTI: your monthly debts, including the new house payment, divided by your gross monthly income. Fannie Mae's Selling Guide allows up to 50 percent on loans approved through its automated system, with lower limits for manually underwritten loans. Your lender may set its own limit.

Loan size matters too. For 2026, the Federal Housing Finance Agency set the conforming loan limit for a one-unit home in Orange County at $1,249,125. A loan above that amount is a jumbo loan, and jumbo loans can have different down payment, credit and reserve requirements. Ask your lender how each option would look for you.

Your Loan Estimate shows the real numbers. The Consumer Financial Protection Bureau says your lender must provide it within three business days of receiving your application.

Beyond principal and interest, plan for:

• Property taxes based on your new purchase price, since a home is reassessed when it sells in California.
• Homeowners insurance, which can vary from home to home.
• HOA dues, if the community has them.
• Upkeep, which usually grows with a larger home.

If one of you is 55 or older, ask the Orange County Assessor about Proposition 19. It may let you move your current home's taxable value to a replacement home in California, under rules the Assessor explains.

That depends on your equity, your loan and how much change your family can handle at once. Some families sell first so they know their exact proceeds. Others buy first with financing that doesn't depend on the sale. Each path has tradeoffs we can weigh together with your lender.

If your family is thinking about moving up, I'd love to sit down with you and map out your numbers before you list. We'll look at what your home could net, the price range that fits your goals, and the timing that works for your family. Call or text me at 714.366.8575 | DRE: 01397168, or contact me.
