The problem with you working on your own is that there are lots of investors out there currently, who have very deep pockets, with a lot of staff, who do nothing but search for foreclosures all day, and it's hard to compete with them because of their resources.
If you have a particular area in mind, a good realtor can help you search the lis pendans in that particular area to see what might be coming up. Or, there is an electonic bidding system in both Dade and Broward's foreclosures. And, both Fannie Mae and Freddy Mac have foreclosures on their websites. But, the competition is very stiff.
If you want to search on your own, we have an REO tab on our website. However, you have to preview & bid quickly, and you need to bid higher than the listed price...sometimes much higher. There are usually 6-15 multi-offers upon which you can bid "highest & best" offer. Sometimes, I find that you can find comparable deals on a regular listing, when you have a really motivated seller, without all the headaches, stress, and countless hours of researching and looking at properties.
Let me know if I can be of further service. I'm very familiar with that area because I sold preconstruction for a developer in that area for 2-3 years. As a matter of fact, there are some great deals w ocean view in that building.
