Two years after signing a lease with a landlord who intended to never sell, he is selling.

I have to choose whether to buy this 3 bdr / 1.5ba, 1450 sq ft house in San Carlos for $888k or rent elsewhere. Here's my analysis...

I would put down $250k, financing $638k. At ~6.125%, my P&I comes out to $3,877. Property tax is around $928 for a total of $4805.

But I can deduct the mortgage interest of $3256. CA + Federal tax is 42%...so I save $1368 (and I already itemize, so it's not as if I lose the standard deduction). That brings me down to $3437.

Then comes something I can't calculate properly...I'd like to deduct the property tax, but I think I'm again in AMT hell this year...maybe someone can help. If I could deduct property tax, it would save my another $390 a month, bringing me down to $3047. Let's go with this for now.

Now if I think that the house won't lose value, I can look at it this way...of the P&I, $620 goes to principal. So that means my 'down the toilet' money comes out to $2427 a month. Renting anywhere on the peninsula in a comparable house is this much or maybe a bit more.

And at this point I'd say 'why not?', except for one thing...the opportunity cost on the $250k downpayment. Even with, say 5% after taxes, that's $1000 a month. Or put another way, if I rent for $2500 / mo, I really only pay $1500.

So then, let's assume I keep the house for 6 years and have to pay a 6% realtor commission. If I figure 5% savings rate, comparable rent of $2500 and $1054 opty cost on my $250k downpayment, it tells me that the house will need to sell for $1,076,000 to break even, or go up by roughly 21% (3.5% per year). If I assume no AMT deduction, I'll need to sell for $1,111,000 - required appreciation of 4.1% a year.

For fun, let's say that the proposed tax change limiting CA mortgage deductions to ~$350k comes into play. It actually makes less of a difference than you would think, at least for me. One one hand, my interest deduction goes down from $1368 to $750. But I can then deduct my state tax. Net, break even sales price becomes $1,130,000; appreciation of 27% or 4.5% a year.

Or, put another way, if the house does not go up in value, it will cost me around $260,000. If it dropped a mere 20%, it would cost me around $420,000.

I'm left with one (financial) reason to buy...inflation. Does anyone see an inflation scenario that makes this make sense to do?

Can you guys check my math?
