Sellers looking for the best realtor to sell my house in Miramar, Seabrook, TX are usually working from the wrong number before they ever pick up the phone. They saw a Seabrook median online, did some quick math, and got excited. Seabrook's citywide median list price ran about $377,000 in August 2026 at roughly $168 per square foot. Miramar's median market value is about $232,555. Those are not the same market, they are barely the same conversation, and pricing your 1960s Miramar house off a citywide headline is the fastest way to spend your best two weeks on the market talking to nobody.
Price to your subdivision, not to your city
Miramar is a specific, knowable place: about 275 single family homes in 77586, on the Harris County side, with a median of roughly 1,544 square feet on a 6,600 square foot lot and a median year built of 1965.
| Miramar metric | Verified figure | What a seller should do with it |
|---|---|---|
| Homes in the subdivision | About 275 | Small enough that three bad comps distort the whole picture |
| Median market value | About $232,555 | Your anchor, not the $377,000 city number |
| Median appraised value | About $229,477 | The county roll, which is a lagging indicator |
| Sold price per square foot | About $153.30 | Running above the appraised $148.63 per foot |
| Value range | About $207,000 to $273,000 | A tight band, so overshooting is obvious to buyers fast |
| Active versus recently sold | About 7 active against 22 recently sold | Thin supply against real absorption |
Read those last two rows together, because they carry the whole strategy. Sold price per square foot is clearing above appraised price per square foot, which tells you the tax roll is behind the street. If your agent prices you off your appraisal notice, you are leaving money on the table. And with roughly seven active listings against twenty two recent sales, you are not fighting a flood of competition, you are fighting the buyer's belief that something better is coming next week. In a thin, tight-banded market the correct move is a sharp, defensible list price supported by three current Miramar comps, not an aspirational number you plan to chase down in $10,000 cuts.
The Highway 146 line, and why it moves your buyer's payment
This is the Seabrook fact that outside agents miss, and it is worth real money at the closing table.
Seabrook is 21.3 square miles, of which only about 5.3 square miles is land. Nearly three quarters of the city is water. Texas Windstorm Insurance Association coverage is available in fourteen first-tier coastal counties, and Harris County is not one of them as a whole. Only parts of Harris County east of Highway 146 are eligible. Seabrook straddles that line.
So two Seabrook houses of nearly identical size and vintage can present very different insurance pictures to a buyer depending on which side of 146 they sit, and insurance is not a footnote. It is a line inside the buyer's monthly payment, which means it is a line inside what they can offer you. A listing agent who can hand a buyer's agent a current windstorm and flood quote for your exact address on day one removes the single largest source of "let me think about it" in this market. An agent who shrugs at the question has just added two weeks to your days on market.
The same logic applies to your appraisal district. Miramar is Harris County, which is a different appraisal district, a different protest calendar, and different taxing units than the Galveston County mainland just south of you. Anyone quoting you a Galveston County statistic for a Seabrook house has told you something useful about how carefully they work.
What sellers of a 1965 house should fix, and what they should not
A median year built of 1965 means your buyer's inspector is going to find things. Sixty year old housing stock in a coastal county has a predictable list, and knowing which items kill deals and which items are just noise is most of the job.
| Item | Deal risk | Recommended seller move |
|---|---|---|
| Original electrical panel or aluminum branch wiring | High. Can block financing and insurance binding. | Have it evaluated before listing. Price the repair into your number or do it. |
| Cast iron or clay sewer line | High. A failed scope renegotiation costs far more than the test. | Scope the line yourself and disclose the result. Control the narrative. |
| Roof age past 20 years | Medium to high in a windstorm county | Get the roof age documented. A WPI-8 certificate history is a genuine selling point. |
| Dated kitchen and baths | Low | Clean, neutral, and lit beats a half done remodel that will not appraise. |
| Foundation movement | Medium | An engineer's letter is worth more than a contractor's opinion. |
Do not renovate your way to a price the neighborhood does not support. In a subdivision with a value range roughly between $207,000 and $273,000, a $60,000 kitchen does not create a $60,000 buyer. Spend on the items that let a lender fund and a carrier bind, then let the pricing do the rest.
Selling now versus waiting: the honest tradeoffs
| Option | Upside | Trade-Off |
|---|---|---|
| List now | Only about seven Miramar homes are competing with you, and sold price per foot is running above the appraisal roll. | Seabrook's citywide median sat around a 75 day market time in August 2026 and prices were flat to slightly down year over year, so patience is required and pricing has to be right on the first try. |
| Wait for a stronger market | You keep your equity position and avoid a soft window. | You are carrying taxes, insurance, and maintenance on a sixty year old house while betting on a coastal market that nobody can forecast reliably, and your competition grows as neighbors list. |
| Sell to an investor or cash buyer | Speed, certainty, and no repair negotiation on the electrical and sewer items above. | You will trade a meaningful share of that above-roll price per foot for the convenience. |
