luxury house plans

I understand maybe a pro tennis player doing this but is it that much of a coincidence that about a quarter of mansions have a tennis court? Is that prime piece of property really worth wasting over a tennis court? Are they THAT much of a tennis enthusiast that they just HAVE to have a court to play on taking up half of their backyards?

I think it would be between 1.5 and 2.5 million. http://www.luxuryplans.com/plan.asp?PlanNum=5608&Plan=6751&PlanGraphicID=16534&Index=56 Isn't it beautiful?

If they made 250k could they afford a 2 million dollar house. What if a family together makes 500/year what is the highest amount they could afford? A radiologist (270/year) is marrying a orthodontist (210/year) They want to build a 7 thousand sqft home in Atlanta and do not plan to spend more than $2million on it but still have high end luxuries.

I am very interested in becoming a doctor and right now that is my main goal. But I know that I am supposed to have a back up plan. Well I figured that since I love to look at different houses and I wouldnt want to be a real estate agent that I should learn how to construct luxury houses in luxury places. I still want to build/design my home anyway. If it cost under 1,000,000 build (materials and work) to build but the amenities (such as large kitchen, extra rooms, a theater and sauna, maybe a home gym, etc.) make the house valued well over $2million, can I sell it for that price. I would love to do that and then I would have made a million when the sale finally went through (I know that it would maybe take a while to sell. With that money I could use it to build more and more and make lots of many doing something I love. Is this a realistic alternative to being a doctor? I would probably need someone to invest but they are almost guaranteed their money back and then some.
