If you own a home in McKinney and are thinking about buying something larger, you may have a surprisingly valuable resource: the equity you have built in your current home.
But here is where I see people get tripped up. They look at an estimated home value, subtract the mortgage balance, and start mentally spending the difference.
I understand the temptation. That number can look pretty exciting. Unfortunately, it is not the same as the amount you can safely put toward your next home.
Before you start falling in love with a bigger kitchen, an extra bedroom, or a backyard that could host the entire neighborhood, let’s talk about how to turn estimated equity into a practical plan.

WHAT DOES HOME EQUITY ACTUALLY MEAN?
Home equity is the difference between what your home is worth and what you owe against it. If your McKinney home could sell for $500,000 and your mortgage payoff is $280,000, your estimated gross equity is $220,000.
That is a starting point, not your spending account.
Selling a home involves costs. Depending on your circumstances, those can include brokerage compensation, title and closing charges, negotiated repairs, concessions, moving expenses and any outstanding liens. The payoff figure may also differ slightly from the principal balance you see on your latest mortgage statement.
Your first question should be: What is my realistic net cash after the sale closes?
START WITH A RANGE, NOT ONE PERFECT NUMBER
Online home estimates are convenient, but they do not know every detail about your property. They may miss an expensive update, an awkward floor plan, a roof concern or the fact that three very similar houses are competing nearby.
McKinney is not one uniform housing market. A home in Stonebridge Ranch may have a different competitive set than one in Craig Ranch, Westridge or an older neighborhood near downtown. Price range, lot size, age, condition and school attendance boundaries can also influence which properties buyers compare.
I prefer to look at recent comparable sales, current active listings, pending competition when available and the likely buyer response to the home’s condition.
Then we build at least three possible sale scenarios: conservative, expected and optimistic.
The conservative number is especially useful. If the next-home plan works only when your current home sells for the absolute highest imaginable price, we need a stronger plan.
AN EXAMPLE OF THE NUMBERS
Let’s use a hypothetical McKinney homeowner with a home that might sell for $500,000.
Estimated selling price: $500,000.
Estimated mortgage payoff: $280,000.
Gross equity: $220,000.
Illustrative combined selling expenses and concessions: $35,000.
Estimated net proceeds: $185,000.The $35,000 is simply a planning assumption, not a standard or required commission or closing-cost rate. Actual fees and concessions are negotiable and property-specific.
Now suppose the owners want to buy a $650,000 home. They might think: Wonderful, we have $185,000 for the down payment!
Not necessarily.
What about cash reserves? Moving expenses? Immediate repairs? Appliances, window coverings or furniture? What if the new home needs a fence, and what if the old house needs a repair before closing?
If the household sets aside $25,000 for reserves and transition expenses, that leaves approximately $160,000 for a down payment and buyer closing costs combined.
That is still substantial. It is also more realistic.
DO NOT CONFUSE EQUITY WITH AFFORDABILITY
A larger down payment can reduce the amount borrowed. But your monthly payment also depends on your interest rate, loan type, property taxes, homeowners insurance, HOA dues and any applicable mortgage insurance.
In McKinney, those ownership costs can vary considerably between homes. Two houses with similar asking prices can produce different monthly expenses because of tax districts, insurance characteristics and association fees.
Ask a lender for a complete payment illustration based on a specific property or realistic set of assumptions. Compare it with your present housing cost and the amount you want available each month for savings, family activities and unexpected expenses.
A lender may approve a number that feels much less comfortable in real life. Your household budget gets a vote.
WHAT IF YOU HAVE A VERY LOW RATE ON YOUR CURRENT MORTGAGE?
This is one of the biggest emotional hurdles for many move-up homeowners. You may be sitting on a mortgage rate that you could not replace today.
That matters, but it does not automatically mean moving is a bad decision.
Consider the total cost of staying as well as moving. Are you already paying for storage? Would you need to remodel? Is the current layout making everyday life harder? Would the next home meaningfully improve how your household functions?
The decision should not be reduced to comparing two interest rates. At the same time, don’t ignore the financial value of your current mortgage. Have your lender calculate the payment difference with realistic loan terms.
HOW MUCH EQUITY SHOULD YOU ACTUALLY USE?
There is no universal right percentage.
Some families prioritize the lowest possible monthly payment. Others would rather retain more cash for emergencies, college expenses, retirement contributions or planned improvements.
A useful discussion includes three options: put down more and borrow less; put down enough to meet loan requirements and keep greater liquidity; or choose a less expensive next home that leaves both a comfortable payment and a healthy reserve.
The best answer depends on your household, not on what a neighbor did.
Also ask about mortgage insurance thresholds, potential loan-program restrictions and whether using additional cash changes the lender’s pricing. These are lender questions, not assumptions to make from an online calculator.
WATCH THE TIMING OF THE CASH
Even if you have plenty of equity on paper, that money may not be accessible until your current home closes.
A purchase contract, earnest money deadline and loan underwriting process operate on real calendars. Your lender and title company need to know exactly where your down-payment funds are coming from and when they will arrive.
Some owners may explore a home-equity line, a bridge product or another financing solution. Those choices introduce costs and risks, and they are not appropriate for everyone. They require careful lender review.
The important distinction here is that your net equity estimate and your available cash on a particular closing date are two different things.
MAKE ROOM FOR THE COSTS PEOPLE FORGET
Moving to a larger McKinney home can change more than the mortgage.
A larger house may mean higher utilities, additional maintenance, more furniture and greater landscaping costs. A swimming pool is lovely until you remember it comes with its own monthly budget. The pool does not clean itself, despite its excellent public relations.
Newer neighborhoods can also have different HOA arrangements or tax obligations. Check the actual property, rather than assuming the costs match your current house.
Build a first-year ownership budget, not just a closing-day budget.
A STRONG EQUITY PLAN HAS THREE NUMBERS
I encourage move-up buyers to know three figures before seriously shopping.
First: realistic net proceeds from the current home, based on a market analysis and estimated transaction costs.
Second: the maximum all-in monthly housing payment the household is comfortable carrying, including taxes, insurance and other recurring costs.
Third: the amount of liquid savings the household wants to preserve after both transactions.
When those three numbers work together, your search becomes more focused. You are less likely to fall in love with a house that leaves your budget stretched.
WHAT IF YOUR HOME SELLS FOR LESS THAN EXPECTED?
Plan for it before it happens.
Ask how a $10,000, $20,000 or $30,000 reduction in expected proceeds would affect your down payment, cash reserves and purchase budget. Could you still buy the home comfortably? Would you need to adjust the price range? Would you prefer to wait?
A plan with options is much better than a plan that depends on everything going perfectly.
WHAT ABOUT TAXES ON THE SALE?
Some homeowners may qualify for the federal home-sale gain exclusion if they meet applicable ownership, use and other requirements. The gain is not simply the cash you receive at closing, and eligibility is individual.
If you have made major improvements, previously rented the property, used it for business or have other complicating circumstances, consult your CPA before assuming the sale is tax-free.
Texas property-tax obligations on the next house also deserve a property-specific review. Your current exemptions or tax bill do not automatically tell you what your new bill will be.
THE BEST NEXT STEP FOR MCKINNEY MOVE-UP BUYERS
Before touring homes, let’s establish a realistic value range for your current property and a preliminary seller net sheet. Then work with a trusted lender to model payments for your next price range.
We can compare several scenarios without assuming the most optimistic outcome. That gives you permission to dream about the next house while keeping your financial footing.
The goal is not simply to buy more square footage. It is to make a move that supports your life, protects your flexibility and still feels right after the moving boxes are gone.
