Basically, I took my mortgage amortization schedule (non-highlighted columns) and added assumptions about my current rent vs:
* Additional expenses from home-owning (property tax, maintenance)
* Interest expense
* Less tax savings (from claiming mortgage payments on my return, plus the $8k first-time home buyers' incentive)
* And the opportunity cost of investing the down payment and purportedly getting a 6% return over the next 30 years.
I break even more or less over 30 years on expenses, so it's all about the capital gain at this point.
I didn't index anything to inflation, though. Once I add that in, it's a very sad commentary on home-buying. Or perhaps inflation is just sad in general!
