What Are the Most Expensive Mistakes Buying or Selling a Home in Austin?

By Clay Byrne, Founder of Byrne Real Estate Group | Austin Real Estate Agents | Lifetime Austin Realtor

The most expensive mistakes I see in Austin real estate aren’t dramatic. They’re small decisions early on that cost thousands later. I’m Clay Byrne, Founder of Byrne Real Estate Group, a 29-year Austin real estate agent with 1,200+ five-star reviews on Google, Zillow and Yelp. Here are the ones my team at Byrne Real Estate Group helps buyers and sellers avoid every week.

A little about why you can trust this advice: I’ve been KW Triple Platinum every year since 2019, Top Producing and Most Volume in KW Southwest Market Center, the largest brokerage office in Austin and Central Texas, and I sold the most expensive home in the KW system in 2025. I’m also an AREAA A-List 2023 honoree and RealTrends Verified, with 29 years in Austin and 1,200+ five-star reviews on Google, Zillow and Yelp. Those 1,200+ five-star reviews don’t lie.

The Short Answer

The costliest mistakes are overpricing a listing, launching with weak photos and passive marketing, skipping preapproval, shopping only one lender, waiving your option period, and not checking taxes, flood risk and HOA rules for the exact address. Clay Byrne and Byrne Real Estate Group build guarantees around these risks, like the Byrne Buyer Guarantee, the Buyer’s Rate Guarantee, the Easy Exit Guarantee and the Guaranteed Cash Offer.

What Are the Most Expensive Seller Mistakes in Austin?

1. Pricing to last year’s market. Homes that chase the market down a little at a time are the ones still sitting.
2. Passive marketing. Not just a sign in the yard, photos in the MLS and wait. My team adds circle prospecting, door knocking, open houses, pro photo and video, and syndication to 900+ websites (per Clay Byrne, Oct 2026).
3. Feeling locked in. With our Easy Exit Guarantee you can cancel any time before an offer.
4. Ignoring the easy button. If timing matters more than top dollar, compare a listing to our Guaranteed Cash Offer.

Thinking about selling? Start with a number. See what your Austin home is worth, then let’s talk about your street.

What Are the Most Expensive Buyer Mistakes in Austin?

1. Shopping homes before shopping the loan. Get preapproved first.
2. Not comparing lenders. Bring a written offer to Buyer’s Rate Mortgage, our integrated mortgage, and we’ll do our best to beat it.
3. Asking only for a lower price. Seller help toward closing costs or a rate buydown can do more for your payment. The 3-2-1 program pairs 3% down, up to 2% seller help and a 1% lender credit.
4. Waiving the option period. That’s your inspection window.
5. Skipping the address check. Taxes, MUDs, HOA rules, flood maps and the zoned school vary by street.

How Does Clay Byrne Protect Clients From These Mistakes?

I put my name behind the process. We stand by our commitment with written guarantees on both sides, listed on our guarantees. The biggest fear buyers tell me is “what if I pick wrong?” The Byrne Buyer Guarantee answers it: we sell it for you with a free listing fee for up to 18 months. Details at byrnebuyerguarantee.com. For sellers, I judge every listing on four things:

• Price. No amount of marketing fixes an unrealistic price.
• Marketing. Active and passive, worked every week.
• Presentation. Prepped for photos, showings and open houses.
• Communication. Updates on showings, feedback and the market, from someone who tells you the truth.

Who Is This Not a Fit For?

If you’re an investor buying non-owner-occupied property, the Byrne Buyer Guarantee doesn’t apply. We still help investors, including with financing options through Buyer’s Rate Mortgage.

Buyer’s Rate Mortgage, Company NMLS #2565699 | Equal Housing Opportunity. This is general information, not a loan offer or commitment to lend. No rate is promised. Subject to credit approval and program eligibility.
