I'm creating my buyers list and I'm starting with searching the MLS for cash buyers within the last 6 months. On the county's website, they have "current owner" and "owner of record"; if there are different names under each of those headings, which would I target, current owner or owner of record?

Also, for whatever reason, no matter how many houses an individual buys, the owner address is always the same as the property. For example, if the assumed investor bought 123 Main St, 123 Main St would come up as the owner address. If the same investor bought 456 Random St, that same address would also come up as the owner address. There are no other addresses listed on the page with the property/owner information. My question is, should I try and contact the assumed investor at that address or would that be a waste of a stamp, (thinking that the address is an investment home being flipped, wholesaled, etc).
