@Vito DiIennaWhile I have not had to get a Letter of No Objection myself, if I had to do it, I would go right the the DOB, go into the Office that you can get an official Cert of Occupancy and ask them what is the procedure to get the letter.Normally, you will need to provide evidence.

The contract should have outlined the amount of earnest money you deliver.

And you can't be of service, if your not delivering value, so one will make themselves of value. 

Also, find a copy of the short sale Approval Letter from your lender and read it again, thoroughly.

Once a default has occurred - be it missed monthly payment, note maturity, etc, the note holder or their representative send a letter to the debtor notifying them of the default and providing the statutory timeline for corrective action.

Also understanding how things are put together, how siding works, gutters, etc (basically as many aspects of the home as possible)Having this knowledge will also help you from getting burned by contractors telling you things just so they can save time and money and deliver a crappy service. 

Will mail be delivered even if A and B are not officially registered with the USPS?

I initially negotiated the terms of the deal through a Letter of Intent and then developed and executed a Purchase Agreement.

However, there are still some great opportunities within Charlotte that can deliver strong investment potential.

Also at closing: You should provide proof that the lender is named as such on a valid hazard insurance policy effective at least on the day of closing.Regarding the closing to sell or refi, yes, your lender will just need to provide a payoff letter with wiring instructions to the closing agent.
