Hope you will see that foreclosures don't always translate to the be the best deals. When buying foreclosures, you won't be in a position to negotiate for more reduced price, repairs, credits.
If you have abundant time and patience, you should also consider short sales.
And.,,,this kind of info isn't available only from your agent. Again, if you have the time and if you're resourceful enough, you can go to your local county records office and get this info since notices of default, trustee sales, etc. are public record.
You can also contact a title company and see if they can give you copies of these notices. It helps to have a REALTOR who can get this info on your behalf, too.
That said, you may want to look at properties in the price range you want. If your agent's company has a service that provides automatic email notification every time a new listing comes up that meets your search parameters, then you should request for that service. You may be surprised to find foreclosures, short sales and regular sales in the mix.
Or you can sign up at RealtyTrac and other similar sites (and pay a subscription fee for the service)
