He likely had a mortgage payment over $10k/ month and taxes of $2-3k/mo, some of each being tax deductible.
Right. He bought for $2.5M. Sold for $3M. Even accounting for costs and the renovation, he likely recouped all of that mortgage and taxes in the sale.
Assuming 20% down (though, that's a big down payment), his mortgage of $2,000,000 would have had a mortgage payment of $9,548.31 at 4% interest on a 30-year fixed (though he could have gotten much lower on and would have been wise, given his profession, to do a 10-year ARM.
Regardless, I'll go with the 30-year fixed. Three years later, he'd have paid $240,013.44 in interest, and $113,273.90 in mortgage payments. His property tax bill looks to have been about $34,408.52 per year, for about $103,225.60, per the Assessor's office. I'll make an educated guess of homeowner's insurance costing about $2,000-2,500 per year. That's another $7,500.00.
That puts his total cost at $964,012.94.
As you mention, the property tax and interest is deductible, though I believe there is a limit to the interest in the first million on the home? So his deduction is about half the interest ($117,000) plus the tax of about $103,000.00. Putting him in the 39.6% tax bracket, that's a tax savings of about $88,397.34. Putting his total cost at $875,615.60.
He sold for $3M. I'll assume broker fees, etc. of about 5%. That leaves him $2,850,000.00. He has to pay off his remaining mortgage balance of $1,886,726.12. That leaves him $963,273.90. After taking out his expenditures, he profited $87,658.28.
I'm not sure how much he put into the home, but as I recall that is deductible at least as to any capital gains. He probably did lose a little bit of money with the renovations. Even if he put $150,000 into the home, that's an all-in cost of $63,000.00 to live in a great house for 3 years. Not bad.
