This is what’s happening in real estate: the rich are getting richer and buying up trophy properties, sky’s the limit. The rest of us can eat cake.

Case in point: 3820 Gillon Avenue, owned by Randall and Olamaie Fojtasek, a former partner at Hicks Muse who co-founded the private equity firm Brazos Partners. The Fojtaseks bought their home in 2006 for a cool $7 million. Back then, Frank Purcell listed it, Joan Eleazer represented the buyers. The home is currently appraised by the Dallas County Appraisal District at $8,500,000.

Here’s why everyone’s talking: the house sold — it sold for — get those smelling salts ready, $15,000,000. In case your eyes are blurring, yes, $15 million. I know it’s appraised at $8.5, go tell the buyer. And get this: it wasn’t even on the market or in MLS. I believe the agent involved is Allie Beth Allman. So this is one of those rare sales that won’t be helping perk up our market numbers, but it is very real.

I don’t know who the buyer is, yet. The home is exquisite: 10,380 square feet built in 1990 but completely and deliciously redone on the interiors, plus the home sits on a 175 by 226 lot which is just shy of an acre in the honeypot of Highland Park. The Fojtaseks paid about $132,999 in annual property taxes. We should send the new buyer flowers and a civic thank-you note — his bill will just about double.

This is why I tell you all the time not to get all upset over the doom&gloom news out there — real estate is a hyperlocal story, and if you happen to own property in a sweet spot, you may even find yourself with some appreciation. Of course, it helps if you are a gadzillionaire with property south of the Highland Park golf course, in the Gillon, Miramar, Euclid, Lexington area.

Yep, the rich are getting richer… and so are their houses!

Hopefully, he’s not going anywhere, maybe just closer to Cowboys Stadium? Jason Garrett just put his gorgeous Highland Park home on the market late Friday with none other than broker to the rich and famous Allie Beth Allman listing it. Asking: $1,950,000. The Ivy Leaguer (Princeton, Columbia) just got named head Cowboys coach January 6, the 8th head hocho in Cowboys history.

The traditional home is on Lindenwood, east of Byron, on a 50 by 150 lot so typical of the choice Highland Park area. It’s more than 4,000 square feet and offers the lucky buyer four bedrooms, four and a half baths, three stories, and pool. (If those walls could talk…) New-ish construction, too: the home was built in 1999 and likely updated.

On November 8, 2010, Garrett was named as the Dallas Cowboys’ interim head coach following the firing of Wade Phillips. On November 14, 2010, Garrett won his first game as Cowboys head coach, beating the favored New York Giants 33-20 in the Meadowlands. Then he led the Cowboys to a 35-19 victory, their first home win all season.

Allie Beth is also listing the Wade Phillips home over on Norway abutting St. Mark’s, listed for over three million. Thank God for these coaching revolutions — keeps our market and Allie Beth hopping! Garrett bought Lindenwood in April of 2007, gosh four years ago, and paid about $1.9.
