Welcome and good luck.
I suspect your best bet may be to drive around and see whose For Sale boards are up on the right sort of properties, and then keep tabs on those agents. Personally I'd ring the top three every week or two or three; some properties may not make it to the internet
- and if they remember you (because you called recently) they just might give you a call when something comes in that may suit you
Modified to add - oh, and get the local newspaper (mailed to you if you are out of the area) - the one(s) which have the best selection of the sort of property you are after. That will help identify the right agents to be keeping in touch with, too, as well as letting you know what's on the market at the mo.
