Quick analysis. Here is a modestly priced condo in Bellevue:
It was on the market as a rental a short time ago at $1,650 a month. Here is a breakdown of what it would cost to buy with traditional financing:
Principal and Interest: $2,389 a month
Taxes: $442 a month
HOA fee: $271 a month
Insurance: $184 a month
Total monthly payment: $3,386
So, he would have to pay $1,736 a month more to own than to rent (basically more than double his rent). Now, he would be able to write off the taxes and about 80% of the P and I early on, but only that which is over and above what he would get from the standard deduction from his taxable income. So, $5,304 in taxes and $22,934 minus $12,550 (or $10,384) he might have a couple more write offs if he donated to charity. So his income tax will be reduced by $15,688 times his marginal federal tax rate (WA does not levy a state income tax, I'll assume he's in the 25% tax bracket), so he would avoid having to pay $3,922 in income taxes each year.
So, currently he would be paying $19,800 a year in rent for this unit.
If he were to buy it and finance it at today's rates on a traditional thirty-year fixed with 20% down, he would pay $40,632 a year, he would pay $3,922 less in income tax and he would retain about $5,700 a year in principal during the first five years or so of his loan. So, real cost would be closer to $31,000 a year.
In order for this to be a profitable investment for jamin, the property would need to appreciate in price by at least $11,300 per year (a big question mark given the rise in interest rates and likely decline of the market) and he would have to hold it long enough to overcome the transaction costs associated with buying and selling a property (typically about 6%) and whatever maintenance he would have to perform to the interior of the property (paint, light bulbs, etc.). He might be able to do better with a property with multiple bedrooms and rent out one of the other rooms.
In my opinion, he is better off renting for now.
