What Happens If Your Appraisal Comes in Low in Flower Mound, TX?
If you're financing the purchase, your default right to terminate and get your earnest money back depends on whether you've changed it with the TREC Addendum Concerning Right to Terminate Due to Lender's Appraisal (TREC 49-1, TXR 1948). That addendum lets you waive your right to terminate entirely, partially waive it with an agreed floor value, or add more protection than the standard contract already provides. Which option is in your contract decides how much cash you're exposed to if the appraisal comes in short, and it's become a real factor in Flower Mound, Southlake, and Argyle whenever a listing draws more than one offer.

Appraisal gaps aren't rare anymore in this corridor. With inventory tightening again this summer and well-priced listings in Flower Mound and Southlake pulling multiple offers, more buyers are waiving protections or writing gap coverage to win. If you're planning a move-up purchase in the next 6 to 12 months, this is worth understanding before you're sitting across from a seller's counter with a deadline attached.
Why This Keeps Coming Up in Flower Mound and Southlake
Here's the mechanic: your lender will only lend against whichever number is lower, the appraised value or your contract price. If you offer $1.65M on a home and it appraises at $1.6M, your loan is based on $1.6M. That $50,000 gap doesn't disappear. Someone has to bring it to closing in cash, or the deal has to be renegotiated, or it falls apart.
In competitive DFW submarkets, gaps in the $10,000 to $45,000 range show up regularly right now, especially on homes priced above recent comparable sales or on new-construction lots where there isn't much comp data yet. That second part matters if you're weighing something like Furst Ranch, Lakeside, or Whyburn, where a fresh subdivision can mean the appraiser is working with thinner data than in an established neighborhood.
For move-up families, this hits differently than it does for a first-time buyer. You're often financing your next home while your current one is still on the market or just under contract. An unexpected $20,000 to $40,000 gap isn't just a math problem, it's a cash-on-hand problem at the exact moment your equity is tied up in a house you haven't closed on yet. That's part of why synchronizing your sale and purchase matters so much in this market. It's not just about timing moving trucks. It's about knowing what cash you actually have available if an appraisal comes in short.
What the Appraisal Addendum Actually Does
This addendum only attaches to financed offers that already include a Third Party Financing Addendum (TXR 1901, TREC 40-9). It doesn't apply to cash offers, since there's no lender-required appraisal for it to attach to.
It also doesn't apply to FHA or VA financing, but not because those loans are somehow excluded from the financing addendum. FHA and VA loans already come with their own federally mandated appraisal protection baked in, known as the FHA amendatory clause and the VA escape clause. That clause guarantees the buyer the right to terminate and get their earnest money back if the home doesn't appraise for at least the sales price, and it can't be waived by the buyer, the seller, or the lender. It's a HUD and VA requirement, not a negotiable contract term. Texas's Third Party Financing Addendum already builds that federal language in for FHA and VA deals, so there's no waiver, partial waiver, or extra termination right left for the 49-1 addendum to add. If you're buying with FHA or VA financing, you keep this protection no matter what your offer says.
For conventional financing, the form gives you three checkbox options, not an open-ended custom clause:
- Waiver. You give up your right to terminate over a low appraisal entirely. If the appraisal comes in low and your lender trims your loan amount, you're on the hook to bring whatever additional cash is needed to close, with no ceiling. This is the strongest offer in a bidding situation, and the riskiest for you.
- Partial Waiver. You and the seller agree in advance on a specific appraised value as a floor. If the appraisal lands at or above that number, you can't terminate over it, so you know your worst-case cash number going in. If it falls below the floor, you keep your right to terminate and get your earnest money back. This is how most buyers actually cap their exposure instead of writing a full, open-ended waiver.
- Additional Right to Terminate. This option gives you more protection than the standard financing addendum already provides. You name a minimum acceptable appraised value and can terminate if the home doesn't hit it, even if your lender would technically still fund the loan. It's rarely the option that wins a multiple-offer situation, but it's worth knowing it's there.
If you skip this addendum entirely, you default to the appraisal protection already built into the Third Party Financing Addendum (Paragraph 2B): if the appraisal comes in low, you can typically terminate and recover your earnest money, or try to renegotiate with the seller. That's your safest position, and also the one most likely to lose to a buyer down the street who checked "Waiver."
Checking "Waiver" instead of "Partial Waiver" is a meaningfully different risk, not a matter of degree. Once you waive fully, you've committed to closing regardless of what the appraisal says, and your earnest money is exposed if you can't produce the difference in cash. Have your agent walk through all three checkboxes with you, line by line, before you sign anything.
How Much Should You Actually Be Willing to Cover?
There's no universal number here, but a few questions get you most of the way there:
- What's your liquidity after closing costs and your down payment? Don't write a gap number you'd have to borrow against or pull from a source that isn't already sitting in cash.
- How thin are the comps? A resale home in an established Flower Mound neighborhood with recent, similar sales nearby is a lower appraisal risk than a new-construction home in a subdivision that's still building out.
- How much do you actually want this specific house? A Partial Waiver floor set $15,000 to $20,000 below your contract price is often enough to make your offer competitive without exposing you to an open-ended number.
- What does your lender say? Some lenders will let you restructure your down payment to cover part of a gap without changing your total cash to close. Ask before you're under contract, not after.
I walk every move-up client through this math before we write an offer, not after we get an accepted contract and discover the appraisal came in light. The number should be a decision you made calmly, not one you're making under a three-day deadline with your relocation truck already booked.
Protecting Yourself While You're Also Selling
If you're buying and selling at the same time, which is most of the families I work with in Flower Mound, Southlake, and Argyle, an appraisal gap on the purchase side compounds fast. You could be covering a gap on your new home while still waiting on your current home's closing to fund it.
A few ways to reduce that exposure:
- Keep a defined cash buffer set aside specifically for a possible gap, separate from your down payment and moving costs.
- If you're using a bridge loan to buy before your current home sells, confirm with your lender whether gap coverage affects your qualifying numbers on the bridge.
- Talk to your agent about whether a Partial Waiver versus a full Waiver actually changes your odds in this specific multiple-offer situation. Sometimes a $15,000 floor performs just as well as a full Waiver, and sometimes it doesn't. It depends on the seller and the other offers on the table.
This is exactly the kind of decision that benefits from someone who's negotiated both sides of a synchronized sale and purchase before, not just one transaction in isolation.
Frequently Asked Questions
What happens if I skip the appraisal addendum and the appraisal comes in low?
If your Third Party Financing Addendum is intact, you typically have the right to terminate and recover your earnest money, or renegotiate the price with the seller. You'll need to deliver written notice and your lender's statement by the deadline in your contract, generally a few days before closing, so don't sit on it.
Is it ever a good idea to check "Waiver" instead of "Partial Waiver" in Flower Mound?
It can strengthen your offer significantly in a multiple-offer situation, but only if you have the cash reserves to absorb an unlimited gap without disrupting your closing or your move-up timeline. For most of my clients, a Partial Waiver with a defined floor gets nearly the same competitive advantage with far less exposure.
Do new-construction homes in communities like Furst Ranch or Lakeside appraise differently than resale homes?
Often, yes. New subdivisions can have fewer comparable recent sales for an appraiser to work from, which can make appraisals less predictable in either direction. It's worth discussing appraisal risk specifically before writing an offer in a newer community.
Who decides how big of a gap I should offer to cover?
You do, based on your actual cash position, but your agent should be running the comps with you first so the number is grounded in what the home is likely to appraise for, not a guess made under pressure.
Can I change my gap coverage after my offer is submitted?
Generally not after the seller has accepted it. This is a number you want to settle before you submit, which is why it's worth a conversation with your agent and lender ahead of writing the offer, not during a bidding deadline.
