Hi Jeff, there's quite a bit available right now. If you are going to rent the condo, make sure that the condo allows rentals. Some (most) have a maximum number of renters/investors allowed in the development, so even though properties are available for purchase, many are unavailable for rental.
Also, as an investment, it's still very tough to purchase and achieve positive or even neutral cash flow (i.e., your mortgage + condo fees + taxes exceed rental income). So, in a negative cash-flow situation, you are counting solely on future appreciation. You have to buy really low, invest money in every month, and then plan to sell in the future and get a return from your total investment. Right now this traditional investment model is still very risky. If you plan to live in this unit initially, then the numbers can be more favorable.
If you want to investigate this further, then find an agent that *really* knows Bethesda condo market to identify the best opportunities (I do some business in the area, but I'm definitely not a Bethesda condo expert). You will make or break your investment return on the purchase. Get it wrong, and you'll pay later.
Good luck -- you are a brave guy!
