It is unlikely I will be able to collect on a judgement.

I can take documents to and from him to get signed since the house is nearby, but physically he may not be able to make the trip to a closing table.2) I did a tax lien search in Maryland on the Maryland Judiciary Judgment and Liens Search, and his name did come up numerous times in the past, but it shows on the records that each judgement and dollar amount has been satisfied.

If it does, and you get a major lawsuit and have a $1 million judgement and lose all your properties, you can declare bankruptcy and preserve every dollar of equity in your primary residence, you cannot do that with a rental. 

This way if you find out that there are other liens or judgement that cant' be dismissed, then you can walk way with your only financial loss being the cost of running title. 

I evicted, got a judgement, and let the local Housing Authority know about the judgement. 

Maybe landlords shouldn't be making personal judgement calls.

There's no judgement intended for anyone based upon ancestry.

But some interesting judgements.  

During my hearing, I did invite the board up to my unit to meet my roommate and to see that my contents (clothing, furniture, etc) were indeed in the unit, but they refused before passing judgement. 

(They think that the debt will attach to them and they will end up with a foreclosure and or judgement against them.
