I'd rather go through an "official" procedure and cover my behind just in case.I imagine that each state has different procedures.

Ask about what their processes are to react to maintenance, rent collections, tenant inquiries, applications, leasing, etc.....If you don't agree with or are uncomfortable with their processes and procedures, keep interviewing. 

I don't know if this is standard procedure but my lender was very strict.

If they insist that you do, it's a violation of RESPA (Real Estate Settlement Procedures Act) and us called "steering".  

I've read plenty and sure I can read some more, but I have yet to find a resource that details the various procedures in dealings and transactions.

Of course, even though it should not delay closing, the repairs have to be made within the timeline and reinspected per the specific municipality guidelines, like Jon said.The Pennsylvania Municipal Code and Ordinance Compliance Act (MCOCA) sets forth procedures which must be followed by municipalities that require property maintenance and other code inspections upon the sale of a residential property.

Tax sale laws and procedures are very state specific. 

It is all quite seamless.No one except the attorney and me know exactly what the procedure was and what the numbers were.

If and when she is a single day late on rent prior to move out, then start procedure for eviction.
