Well, right now there are 18 homes for sale in Glen Ellyn with 3 bedrooms, 2 baths and a 2 car garage priced under 330k. You might have a hard time finding a home with those qualities in your desired location during your search in Jan - March of 2009.
If I were you I would have a Realtor start sending you homes in that area with your requests now via the MLS. But, no need to waste the gas right now and driving around. Let me ask you this, if you found the home with 3br/2bath/2 car garage w/yard for 300-330k north of Roosevelt Rd and South of Geneva Rd and you liked it, are you ready to buy now? Right now? Not in 6 months.
There are not a lot of homes in that price range in that location so it may take a while for you to find what you want. You question cannot really be answered unless I knew a lot more information. A lot of homes might meet your 3 bedroom, 2 bath with a 2 car garage but that does not mean it will be the layout you want or the size rooms you desire.
I would suggest you get on an MLS search that will show you whats available. If you are a little flexible with location you will really open up your options. Feel free to give me a call-I can give you a better idea of what your going to get for your money!
