I arranged and set up the home inspector, generator inspector, appraiser, septic pump out and inspection, and a flooring/repair guy.

Mailmen, Police Officers, Garbage Men, City Inspectors make AMAZING "Informants". 

Hiring an inspector isn't a guarantee.

We found from reference of our higher volume clients that we are about 10% more expensive then when they GC themselves, but about 50% faster in terms of turnaround time, and very few failed inspections because they have a GC who is running the process and holding subs accountable for work before building inspectors ever have a chance to.

She paid the February rent and security deposit.The Housing Authority inspector came by and the unit passed.I'm waiting on March's check from the Housing Authority as the first one is via a check versus direct deposit.

Do you have relationships with people in Baltimore Housing whom you can call upon to help sort out one inexplicable delay (getting an inspector out, getting a check sent, whatever) or another? 

You can hire the same property inspector to do a walk through again.

If the inspection is done on the house and the inspector comes back and says there is one pipe inside the house which possibly could be asbestos.

You can always just treat your contractor as your inspector.

When I was a HUD inspector I came across squatters all the time,  They know what they are doing.
