We know what to expect with Free information. Sure there are some addresses that you can research, but keep in mind... this is a business. The Free information will most likely not be the most current and could lead to quite a bit of disappointment when 'sleuthing' on your own. If you want the updated info, buck up for the subscription- even for a month. You will see the difference.
If you don't want to spend the money, I would suggest working with a Realtor who specializes in distressed properties. Keep in mind, not every Realtor or agent is really "plugged in" to the pulse of distressed homes. It is up to you to make calls and ask questions, even if it means not working with the first person you speak with. Personally, I meet everyone I work with face to face. Quite a bit of time can be saved by finding out if you are compatible. Building rapport, trust and offering value for service is vital... especially with a transaction such as a home purchase.
