It appears you have your mind made up catchme. Just wanted to make sure you understand that 1) you are likely going to be spending more each month purchasing vs. renting and 2) you will lose at least some portion of your down payment as the market softens...
I ran your monthly numbers and came up with this:
$417K mortgage @ 6% $2,085
Deductible prop taxes $459
Non-deductible MRs $320
HOA $205
Insurance $50
Maintenance $200
Subtotal $3,319
Tax deduction @ 30% ($763)
Foregone interest on $118K $255
Net Expense $2,810
These are monthly numbers obviously. I only considered the interest portion of the $417K at outset. Some will tell you that maintenance should be much higher than the provision I added per month. I bought a new Cal Pac condo in 2001 and have found that I have spent around that per month over my seven years of ownership when I look back over everything. I put tax savings are at 30% but if you are shifting from standard deduction to itemizing, your tax benefit is not likely to be quite that high. If you are already itemizing, it would be more like 35% though...
I'm quite sure you can rent something bigger and just as nice for $2800... I would think you can rent a newer 3/2 with that amount of square footage for around $2500-2600 per month actually.
You talk of no one being able to predict the future. Do you actually believe the market is at or new bottom? I would think you must if you are willing to spend more each month to own. Even if the market only heads down another 10%, your place would go to $480K and then probably take 3-4 years to get back to your purchase price. You'd be five years in, back to even, but needing to pay $30K in commissions to sell the place and move-up.
If mortgage rates shoot up, as they likely are, or prices go down 20-30%, like they could, you will be stuck in that place for quite a long time. Seems like a high risk to take for something that isn't even going to save you bucks every month...
