Hi Jenny,
Usually you will be better off purchasing a single family residence (SFR). As you mentioned, SFR's tend to appreciate faster and hold their value better than do condos. SFR's are generally in higher demand, therefore a bit more expensive. You will usually get more bang for your buck in SFR's. However, all this depends on your individual circumstances/lifestyle. If you don't like to do much maintenance, upkeep, etc., and don't mind the homeowner's association (HOA) fees, then a condo could be right for you.
As to the number of bedrooms, 3 and 4 bedroom homes tend to be the most desirable, more in demand, easier to sell, and more expensive.
You are wise to be looking ahead. In keeping with that mindset, when you do make a purchase, think about how (i.e. positives and negatvies/likes and dislikes) you might sell your home before you buy it. Develop a plan, follow through, and you will make money, as you turn your real estate dreams into concrete realities.
Best wishes to you,
Jim Hargis
