Is there any benefit to visiting DoH offices in person? 

Our offices are in the southern parts of the US so naturally we're more comfortable with buying in our backyard.

I generally get a picture of the letter at the post office with the paid postage on it also. 

Consultants, inspectors, and mentorsProperty managersAssistantsBookkeepers, accountants, and attorneysLandlords if you rent your office spaceYour business partners if you paid them (except if they were strictly lenders)Disclaimer about wholesalers: it is a controversial issue, with some of my colleagues claiming that wholesalers do not need 1099s.

That's the reason there are so many fourplexes and so few fiveplexes or even sixplexes.From what I gather, post offices and utility companies rarely care much about the permitting/zoning issues, so it probably wouldn't have been hard to get those set up.

Much of our back office is centralized / remote based, while our boots on the ground are local to the market / properties. 

Hi Jessica, have you called his office to voice your concerns?

You missed an important item: Depending on how a person does #1 or #2, it could get them: A fast-pass to the "Principles Office" for "bullying" and now there sitting in "detention"....

I recommend starting by contacting the county’s property tax office to determine if they are open to discussing or reviewing an appeal for property taxes.
