Knowing when to offer on abandoned properties

[Aaron Barba]

What's up investors!
I have a question on abandoned properties that I can't seem to understand yet.
Here's the situation: I've found over 75 abandoned properties in my city, yet I'm not quite sure how to determine how much equity some of these properties have, other than the REO's and those in forclosure which state how much is owed, how would I know whether or not it's worth offering on?

Here's a list of what records I have on these properties:
1.) Recorded liens and judgements
2.) I know which properties are REO, and which are in foreclosure
4.) I know which properties are current and behind on property taxes
5.) I have records of deeds with mortgage information stating when they bought and for how much.

Based off of that, and doing my comps, do I have enough information to determine an offer? Or not enough?

Any insight would be greatly appreciated.

Thank you!
