UPDATE: I told y’all something was up with Troy Aikman’s house over on Highland Drive. It’s been taken down from Allie Beth Allman’s website, and MLS now shows the listing is canceled. Naturally, I’m all over this, so stay tuned. It could mean the home is sold, but that’s not what MLA is saying. Or it could mean Aikman has decided to take it off the market. Then I wonder if this has anything to do with the upcoming ban on Z sales.

And the Amends must be getting serious about selling Mount Vernon: They just lowered the price to $24.9 million. Now that’s a blue light special.

When I was asked to put together a list of the most important homes for sale in Dallas right now, I was torn. Which should be no. 1? Troy Aikman's house on Highland Drive? Or the classic, tranquil estate of Teresa and John Amend that once belonged to H.L. Hunt?

I cannot choose. Oh but I have to. So I will.

 4425 Highland Dr., a.k.a. Troy Aikman's Place
I have heard that Aikman's home may be under contract as I type. A couple from Mexico fell in love with it and started negotiations, I'm told. He sold the lot next door to Barbara and Brian Pratt this spring, and they plan to build.

Aikman's home, listed with Allie Beth Allman, was built in 2005. The 10,200-square-feet manse has five bedrooms, six full baths, two half baths, two dining areas and three living areas (at least), and it sits on more than half an acre in the yummiest part of Highland Park. At $14 million, it's nearly $1,400 a square foot.

 4009 W. Lawther Dr., a.k.a. Mount Vernon
 Mount Vernon, also listed with Allie Beth, is still on the market for $29.5 million. For that you get a 10,511-square-foot estate with five bedrooms, nine full and two half baths, and about five living areas on the banks of White Rock Lake. Plus 10 acres, the first swimming pool ever built in Dallas, a four-lane bowling alley, 2,400-square-foot guesthouse, 16-car classic car facility, lighted tennis courts, putting green, wine cellar and pizza oven.

Right now, Mount Vernon is the most expensive listing in Dallas.

 9008 Briarwood Ln., a.k.a. River Rock House
OMG. Have you seen the River Rock House over at 9008 Briarwood? The owners spent five years laboring over this masterpiece, designed by Wilson Fuqua and built by Cy Barcus Jr.

It has more than 16,265 square feet, six bedrooms, seven full baths and three half baths, study, enormous media room the size of Cinemark 17, wine cellar and tasting room with kitchen, lagoon pool, and the biggest crafts room I have ever seen. (It doubles as a tornado room.)

The craft room has two giant Corian tables on wheels conveniently located next to the wine cellar — so, yes, I'd stay here in a storm too. This pup is on about 1.8 acres with a creek running right through the lot, and the whole home is built from handpicked river rock imported from Montana, California and Wyoming. The owners bought the rock from wherever they could buy it and ship it to Texas.

Asking price is $12.995 million, and the home was completed in 2007.

 10660 Strait Ln., a.k.a. Phil Romano's House
Phil Romano lives on Strait Lane, otherwise known as Billionaire's Row. At least until The Creeks at Preston Hollow is sold out.

Romano's brightly colored home is loaded with art — and, of course, it has a completely commercial kitchen. Originally listed for $17 million, Doris Jacobs over at Allie Beth Allman has it listed for only $10 million — highway robbery, I tell you!

You get 4.6 acres, a private lake stocked with bass and a fountain, resort-sized pool, pavilion, jogging trail, tennis court and guesthouse. The 16,000-square-foot home is brimming with eight bedrooms, seven full and four half baths, and nine living areas.

Oh, it is also across the street from what is soon to be the only private water park in Dallas: the home of Medicaid pediatric dentist Richard Malouf.

 2525 North Pearl, Units 2100 and 2101
Okay. So this is not a house, but it's definitely the most over-the-top condo in Dallas. I'm talking about Tim Headington's place at 2525 North Pearl, listed with Pogir at Briggs Freeman Sotheby's.

The SoJo Design Team of Miami combined the two original penthouses, creating a more functional layout. The 8,400-square-foot interior has two kitchens, two bars, four bedrooms (each with a full bath), two powder rooms, billiard room with purple pool table, theater, library and office. There are three wine refrigerators — one for sparkling, one for red and one for white. The condo takes up the entire 21st floor, and it has two elevators.

Three unique outdoor terraces and entertaining spaces were custom-made to withstand 70 mph winds. Epay wood decking houses all of the special lighting. Everything is bolted down to the deck: the furniture, sculpture — even the bar stools! Exterior square footage totals 5,500.

The whole place affords 360-degree views of the city, and it's loaded down with museum-quality art and sculpture. The asking price is $14 mil, and that doesn't include the art — but, hey, it never hurts to ask.

Oh, and, remember Super Bowl XLV? This is where the stars planted themselves.
