@Robyn GershHere in Pa, before I can file a mechanics lien, I would have to take someone to court first and win a judgement.

As I pointed out in your other post, you should try to get an Substitution of Plaintiff or an Assignemnt of Judgement instead of Bid.  

10% of the final judgement amount for a specific property?

These are essential needs for any tenant anywhere (proper insulation for heat and privacy) and it is regrettable that coming to you in an air of cooperation brought negative comments/ open judgements from you that we have never received before.

Using the providers management company is fine too, if you can verify that they've got integrity.. but that adds a bigger judgement factor in there for the buyer which doesn't always work out. 

As you already know, it seems, having a series LLC may provide you the added benefit that if you were subject to a judgement the judgement can only go after your one property where the claim was assessed, thus keeping your other investments and personal assets more secure/protected.

Since you've been to court, why did you not include water bills, and deposit arears in your judgement? 

Basically, the homestead exemption is, in most states, a dollar amount that cannot be taxed or taken from you by a judgement (with the exception of foreclosure of the mortgage to purchase the property). $75,000 seems to be a common amount, but I believe there are a couple of states that don't have a homestead exemption.

Checking the title for Liens or judgements via the local county is best way to start.  

This will give them a mental bias.Should I just rent out the place and let renters use their own untainted judgement about the house?
