(As AZ and your current state will fight over who gets to tax your gains with the federal government.)I have to throw most of the shade on your horrible tax guy/cpa who didn’t tell you renting it out was a $50-$100k mistake. 

The challenge is that non-government jobs are often short-lived.

You have to understand that these people don't care about anything, and the government people are overworked and will not follow up with all the small cases. 

For various reasons, the US government wants to understand the "beneficial ownership" of certain businesses.

Since downtown development land goes for $30 million/acre, $100k imposed by the progressive city government for a 40 story building permit is a minor annoyance.

Lastly, your going to want to get with local governance, a lot more then normal.

Flatline population growth is a sign of a poorly managed state and large or soon to be large, government debts (e.g., Illinois).

Which governing body determines these requirements?

If not, then you really need a strong legal structure stating how these properties will be governed going forward, including management, tenant selection, capital expenses, etc.

These loans do come from banks directly (Fannie/Freddie loans come from the Federal Government) so each bank that offers these types of mortgages might have slightly different requirements.
