I have looked at PG county, Baltimore county in the past, it doesn't quite meet my location/neighborhood criteria. 

With high rent prices, yes, it's harder for poorer families to stay in the city; many end up fleeing to MD/PG county.

I did not see a traditional bank making this kind of loan, with no PG.  

I'm hoping to use this venue to find a community of REIs in the DMV area, specifically PG county, willing to share insights and experiences.

I would think management would still make visits a few times per week and they could set up a rent slot box attached the boiler room door or something of the like.

Gregory Hiban   those credit lines may have had PG's so if things really cratered bank would come after him personally...

So even if he is 100 or 200 negative he is still having someone payoff his mortgage and within a year he could move to another and just keep doing this until he has filled up his 4 or 10 mortgage slots. 

So it's more important that you ask your lender if their loans are recourse / require a PG. 

You share the one hour slot with others and wait for your turn.
