Do you have a specific property in mind or was this a general question?
If the property is abandoned the bank still has to go thru the foreclosure process, which means the home could be tied up for as much as a couple of years before the bank has legal title and can sell it.
If you don't have a specific property in mind, then you could try the Sarasota County Clerk's office. I believe they provide a daily list of foreclosure sales. However, this doesn't seem to be a popular choice for investors, as the majority of the properties are reclaimed by the lending institution who holds the mortgage.
Our company works with several of the banks who list foreclosed properties. If you would like to contact me I would be happy to let you know when we are getting potential listings (before they are listed on the MLS) that meet your criteria.
Hope this helps!
