I have yet to talk to the property owner or get exact addresses, so I still don't know the condition f the properties. 

Or for anything that needs to be addressed after inspection.

I believe the city of Allentown will require it anyway, but I have heard horror stories, fiction or non, about oil companies having the wrong address or doing a routine fill-up that was never canceled, and dumping gallons upon gallons in to basements with no tank. 

Look for properties that seem neglected write the addresses down and reach out to the owners.

I have also used the language:"Inspections are for informational purposes only, however, if the buyer finds a catastrophic electrical, plumbing, foundation, structural, or environmental issue, they reserve the right to see if the seller wishes to address or negotiate the issue."

You should consider an ALTA survey and make sure the easements and other matters in your title commitment are addressed in the survey.

Send address if you’d like me look at it for you.

If not they are addressed prior to a tenant move in. 

Send a letter that you have paid in full the agreed amount, any “changes” gc wants additional money for were to address non-workmanlike results that were expected and ordinary, but that you are willing to pay $20 for the base trim at Home Depot prices (maybe add $30-50 trip charge for worker to go buy) as an offer in compromise or good faith.

I would google the address to see what might be going on.
