it all depends on what you mean with "the best deal".
Buying an apartment is both a very important investment decision and a very important life decision.
Is the Best deal the amount of space you will get for your money, a lower price per square foot?
How long are you planning to stay in the neighborhood? Do you want to buy in an up and coming neighborhood and are willing to live through construction and current lack of transportation for a few years to be able to see the value of your property rise significantly, years from now, or do you want/need certain things right now?
I agree with Richard, buying a property ''on sale" can be like buying a dress "on sale". If you are willing to wear that cheaper dress for a while waiting for it to come back in style, you will be able to get a great price now, if not, a better deal for you is to buy into a nice neighborhood.
My advice would be to start working with a buyers broker who can guide you through the process and help you find the best deal for you!
