There are a few regulations you need to be aware of: 1) The asset being sold must be an investment property and cannot be a personal residence.2) The asset being purchased with the proceeds must be similar to the asset being sold.3) Within 45 days of the sale of the property, you must identify the property(s) or asset(s) that you are purchasing in the like-kind exchange and you must designate the replacement property in writing to an intermediary, specifying the property you want to acquire. 4) The proceeds from the sale must be used to purchase another asset within 180 days from the date of selling your asset. 

Found a designer/architect for the building, have a builder....now I'm trying to understand the land buying process.

I understand the design and build part, but I don't know where to start when it comes to buying the land.

It is constructed out of brick designed to be a triplex.

Perhaps I should keep track of specific details about the structure and designs of the interiors?

When doing my due diligence, I saw that the unit is a designated Affordable Dwelling Unit; however, the 15-year control period has expired.

I am in a design process for a fourplex in Phoenix on a R-3 zoned lot.

That being said, do you truly want a copy editor (words only) or are you also wanting a graphic designer that can make it more polished overall? 

I will get a confirmation about this later today.3) Also, do you know anything about this primary residence designation.

Parking becomes an issue when the number of guest increases, potentially adding another vehicle or two where there is no designated parking spaces could force the vehicles to be parked on a lawn or on the street, thereby countering the objectives of ordinances created by municipalities and or HOAs.
