Tor, I agree with Ken, Dean from Century 21 is a serious realtor and so are Ronnie from Palm Hills Realty, as well as Jim Belair from American Realty DR. Those seem to have the vote of confidence of DR1rs. Not to say that others are not as good but these guys are top notch, why look elsewhere.
As for prices, there seems to be a lot less bargains in what attracts americans (large mansions, condos, gated villas, beachfront). You may still find large houses in non gated and away from the beach or outside the popular tourists areas at a steep bargain but the longer you wait to make a move, the more you'll pay. Market seems to be going up and that's good for everyone. I think the reason the market is going up is certainly not the l economy but rather a change in buyers from germans/european to north americans. Again, that's only my personal observations, nothing based on real numbers.
Good luck in finding real estate.
