I have investors that are willing to pay off back judgements/liens and in return take over the property + put money in the pocket of the distressed home owner.

There was a property that was sold at a foreclosure auction in the county we invest in based on the judgement on the property from the homeowner's association.  

I would think that if the judgement amount on the home is higher than the ARV, for example the house has a judgment of 100k but only worth 90k this would be a good indication that the foreclosure has been brought on by the bank carrying the 1st mortgage on it?

Can't sue them for the remaining 11 months of rent.Take them to court and get a judgement for the damages.

Is there a sticky link or website (there has to be something here on bigger pockets) that would allow you to plug in the numbers and make certain etimates and judgements about the quality of a property of a rental) y'all could point me to?

Since this may require the Collector to first pursue a judgement, that is not all that bad of a deal.  

Seems many folks make judgements just based on a few anecdotal instances or a story that a friend told a friend without getting on the ground themselves to make an evaluation.

To me this is a win/win, this saves me the time/money to have a sheriff come out, it gives him an incentive to not put a sledgehammer through walls, or cause damages, and to him, it prevents a judgement on his credit report, it saves him hundreds of dollars in a judgement, and possibly even will prevent, the eviction from coming up on future landlord screens(which is something I don't like, as these type of people and their actions need to be public record).Thoughts?

You essentially have no leverage since they can continue to foreclose on the property unless you pay the Final Judgement amount.  

Lets say Investor 1 puts in 40% of the loan, Investor 2 puts in 60%; if you default, investor 1 will get 40% of the default judgement amount or proceeds from foreclosure sale, and investor 2 will get 60%.
