Now a 25,000 sq ft mansion with the best views in Arizona and close to Sedona and all of the numerous sights, adventures, and wine county that northern AZ and the Verde Valley have to offer.

If they are individual units, is it better for you to live there and give up your 2 story duplex?

Do I subcontract out all the individual skills or try to find a handyman that can accomplish a wider array of items (like outlets, lighting fixtures, exhaust fans, LVP flooring, etc.) and then hire subs for specialty items (roof, siding repair, painters, etc.)?

@Sean Barnebey you're really looking at two different individuals. 

I am a couple of counties south Hillsborough (Tampa) and in years past, my county attached the water bill to the individual and not the property, but they changed the law and it now attaches to the property.

There could be an advantage to this because you can sell units individually.

I am part of a group of three individuals who are looking to partner to invest in a duplex.

I'm guessing because they were originally focused on renting individual rooms, so people could list individual rooms within a house or list the entire house.

Multifamily real estate syndications are completely different as there could be hundreds of individuals involved, thus some profit sharing.

There are also business loans that are based on the business, although individual guarantee may be required in some cases.Quitting your W2 will make lending harder and more expensive.
