I currently live in Valdosta and own my primary residence and 5 other rentals in the area.

My current primary was purchased in 2018 with a conventional loan.

We have also made countless memories at our primary cabin.

Contrary to your line of thinking here, instead of having the restaurant buy your steak for you or taking steak to the restaurant to have it cooked (for a markup), some might think its better if you bought and cooked your own steak.It does seem in some of the states, you can act as your contractor on a single build or your primary residence; so it would appear if someone can handle the travel between 50+ cities, may not necessarily need a markup GC.

Would they be using the new home as a primary residence or secondary / investment property?

@Luis Lozada many investors borrow against the equity in their primary home, but most forget to include the corresponding payment in their ROI calculations.Also, what are your cashflow goals?

One more question.I was looking at the Inspire HCV Form and there's a star next to "Primary Cooking Appliance Missing" and "Refrigerator is Missing."

I invest primarily in Detroit (12-doors there), but I'm also building an ADU here at my primary. 

Also, if you have more deductions than income, i.e. losses, then normally it means you are losing money.The primary way to go is with depreciation, since its a non-cash deduction. 

The new builds in the outskirt towns are fine and if you buy with a primary loan, you can get a great interest rate.
