You're kidding, right? You know that if you take an investment that returns less than the prevailing interest rates, and lever it up, you lose *more* money, right?
Anyway, to help you understand, I have detailed some of the expenses that Ms. Spears paid, assuming she borrowed 80% as you suggest. I further assumed that she paid 5.75% for a 30 year mortgage with no points.
On purchase: 1.875% of borrowed amount mortgage recording tax, .45% of purchase price for title insurance, .2% of purchase price for mortgage title insurance, 1% of purchase price for mansion tax.
On sale: 6% brokerage fee, 1.425% NYC transfer tax, 0.4% NYS transfer tax
Carrying charges: mortgage expense using the assumptions above would have been about $14,000 per month. I never saw the original listing, so assume about $2500 per month in taxes and $2500 per month in common charges, which seems reasonable for a property of this size and location.
Total costs for 48 months? $1,319,500.
Given that her "profit" on the property was only $1,000,000 this leaves her $319,500 in the hole.
Note that I left out attorneys fees and other minor expenses that would have made the actual picture somewhat worse.
