I don't think this is a bad time to buy given the discounts in asset prices right now, and the low interest rates. Its kind of a "best of both worlds" situation! Are we near or at a bottom, who knows, I'd wager a guess that we are not, but the concept of a real estate "bottom" can vary greatly from region to region. If you buy a nice property in an area that has good long term economic viability, then you should be fine and not need to worry about losing value. In other words, buy in an area where you know people will still be wanting to live in 5 or 6 years from now. Don't buy in an area that is full of foreclosing properties... as the economic viability of that area will drag down your housing value as well.
Adjustable rate mortgages have lost their luster anyways, the interest spreads on them make them not even close to being as attractive as they used to be during the bubble times, so I doubt you'd be offered one. I'd recommend against it, as the long term interest rate outlook is grim. This is a great time to lock in at a low fixed interest rate on a discounted asset.
I think the most important question to ask before buying a property is how solid your employment arrangement is. Do you have good long term job security at your current employer? Do you work for a business that is sensitive to economic fluctuations, and if so, how "high on the totem pole" are you? If there is uncertainty here, you may want to delay buying property and committing to that payment.
One other thing... when looking at condos in particular, in addition to the mortgage, you will also have association fees. Make sure to ask lots of questions about ALL of the fees, and what they cover. I'm not sure what the physical arrangement of your potential new condo is, but some have parking fees, certain payment arrangements for certain utilities, etc. Don't let them surprise you with anything, some of these fees can be steep. Additionally, ask if they have any impending plans to upgrade any of the infrastructure within the condo complex.. as this would potentially signal an association fee increase in the near future. I got burned on this in my old condo, an "improvement project" overran the budget, and the association fee increase grew more than I expected. I had to tighten my belt a bit for a year.
Good luck, and happy condo hunting!
