David is correct. These listings can some times be confusing and they lead people to believe that there are homes on the market that are not yet for sale. Some times the foreclosure process is halted due to payment of the mortgage, a refinance or restructure, or someone just getting their act together. I would suggest finding a buyers agent to work with you to ensure that you are on top of the market.
I am a local Saugus Realtor, as I live and work in Saugus. I just purchased an investment property in Saugus as well. Find an agent that works for you and has a great track record. I would love to help you in any way. I can be reached via my contact info below. That being said, I have worked with David, and he is great as well.
Best of luck to you.
