actually...disagree... He could put down whatever the dp is. His credit is definately good so his interest rates would be low and he could use the rest of the cash to invest in businesses and ventures that would gain him much more income than the little bit of appreciation he might get on his mansion.
The income from using 15 million to start variuos businesses should more than out weigh the interest + any appreciation in value on his property.
yall are acting like he just spent his last penny, or something. paying any amount of interest, when you don't have to, is dumb. and i'm sure he still has plenty of money left to "invest"
(apparently on boxden, you just press the "invest" button, and money starts raining from the sky
