I Have a 3% Mortgage on My McKinney Home - Does It Still Make Sense to Sell and Buy Up Right Now?

I have a 3% mortgage on my McKinney home - does it still make sense to sell and buy up right now? Yes, for many McKinney homeowners the math still works, because the equity you've built often offsets a higher rate on the next loan - but you need to run your specific numbers, not just look at the rate difference.

It's the question Jane Clark hears more than almost any other right now: you locked in a mortgage around 3% during 2020 or 2021, and the idea of trading it for a rate twice that high feels financially reckless on the surface. But a mortgage rate is only one piece of the puzzle. Your home in McKinney has likely appreciated significantly since you bought it, which means you're probably sitting on far more equity than you realize - equity that can be applied directly to a larger down payment on your next home, shrinking the loan amount enough that your new payment isn't nearly as scary as it looks in your head. For some owners, especially those who bought early in a neighborhood like Stonebridge Ranch or Eldorado Heights and have watched values climb for several years, the equity swing can make a move-up payment surprisingly close to what they're paying now. For others, particularly those who bought more recently or have less room to trade up in price, the payment jump can still be real and worth thinking through carefully. This isn't a decision with one right answer for every household in Collin County - it's a decision that depends on your equity position, how much home you want to move into, and how long you plan to stay there. The rest of this post walks through how to think about the trade-off honestly, without either dismissing your low rate or being paralyzed by it.

Why the 'Golden Handcuffs' Feeling Is So Real

If you refinanced or bought during the historically low-rate years, your mortgage payment is likely locked in at a level that today's buyers can only dream about. Giving that up on paper feels like a financial mistake, and that hesitation has kept a lot of would-be move-up sellers in McKinney sitting tight longer than they otherwise would.

But staying put has a cost too. If your family has genuinely outgrown your current home, or you're commuting past the neighborhood you actually want to live in every day, the rate you're protecting isn't free - you're paying for it with square footage, a lot size, or a location you're not fully happy with.

The Real Question Isn't Your Rate - It's Your Payment Delta

Instead of comparing your old rate to today's rates in isolation, compare your actual monthly payment now to what your monthly payment would be on the new home, after applying your equity as a down payment. That delta - not the rate spread - is the number that actually matters for your budget.

Homeowners are often surprised at how much smaller that gap is once real numbers replace assumptions. A $150,000-$250,000 equity position, which isn't unusual for someone who bought in McKinney or greater Collin County several years ago, can meaningfully reduce the loan amount on the next purchase.

Your Equity Is Doing Heavy Lifting

Home values across McKinney have risen substantially since the low-rate years, and that appreciation is sitting in your house right now as unrealized equity. Selling converts that paper gain into real cash you can put toward your next home, which is the single biggest lever for offsetting a higher rate.

Move-Up Inventory Looks Different by Price Point

It's also worth knowing that the move-up segment isn't behaving identically to the entry-level market. If you're curious how competitive it is to sell where you are and buy where you want to be, our post on whether the $450-550K starter segment is actually selling faster than the $700-850K move-up segment breaks down how pricing tiers are moving right now.

When Selling and Buying Up Still Makes Sense

• Your current home has significant equity relative to what you originally paid
• You plan to stay in the next home long enough to justify the transaction costs
• The home you're in no longer fits your household, commute, or lifestyle
• You've run an actual payment comparison, not just a gut-check on rates

When It Might Not Make Sense Yet

• You bought very recently and have little equity built up so far
• The payment jump, after applying equity, still stretches your budget uncomfortably
• You're only a year or two from a life change that might affect your housing needs anyway

If your instinct is to buy your next home before your current one sells, it's worth understanding the tools available to bridge that gap. Our post on bridge loans versus contingent offers lays out the pros and cons of each approach for McKinney sellers moving up.

Strategies That Can Soften the Rate Jump

A few practical levers can narrow the gap further once you're ready to move forward:

• Negotiating seller concessions on your purchase to buy down your new rate - see our breakdown of how much in seller concessions you can realistically ask for right now
• Applying a larger portion of your equity to the down payment to reduce the loan balance
• Considering whether current conditions favor buyers, since that affects your negotiating room - our post on whether McKinney is actually a buyer's market right now is worth a read before you write an offer

Why Location Still Matters in the Math

Where you're moving to within McKinney or Collin County affects both your sale price and your next purchase price, so it pays to think locally rather than in national averages. A move within the same McKinney ISD boundaries or a shift to a growing area like Trinity Falls or Painted Tree can change your numbers meaningfully compared to jumping into a completely different part of Collin County.

FAQ

Will I lose money by giving up my 3% mortgage?

Not necessarily. You're not losing the value your low rate provided - you're trading it for equity gains and a home that better fits your current needs. The comparison that matters is your new monthly payment after equity is applied, not the rate itself.

How do I know if my equity is enough to offset a higher rate?

The only way to know for sure is to run your specific numbers: your estimated sale price, payoff balance, closing costs, and the price and rate on the home you'd move into. A side-by-side payment comparison makes the real gap obvious.

Is now a good time to sell in McKinney if I want to buy up?

It depends on your price point and timeline, since different segments of the McKinney market are moving at different speeds right now. Reviewing current local conditions before listing helps you set realistic expectations for both your sale and your next purchase.
