I will let an expert like @Michael Plaks or @Brandon Hall answer that, because there may be limitations when remodeling a non-rented building.

Only the partnership/llc can do a 1031 making your options limited if you do not have a control over the partnership.

If so, then yes, find out what sold comps (per sq ft) go for.If not, why limit your search to 2-4 unit properties only, rather than 5+ too?

Due to limited funds I’m doing most of the rehab myself and only subbing out a few things so it’s taking me longer than I’d like.

If it doesn't get better, good people will avoid investing in real estate and the housing will be controlled by slum lords or government.

This structure will let you capture the capital gains on the land thus far without it triggering capital gains taxes (assuming you don't trigger any of the limitations on the sale of your personal residence, or the gains are more than the exclusion). 

I have limited land development experience -- a couple of boundary line adjstments and a short plat.  

They equal the same if they are in your control, or the house's control.Using the rent to pay off your principle, is using HER money.Using your cash to pay off the principle is using YOUR money.Her money is FREE to you..and it pays for all of your costs/expenses so you don't have to pay them...so don't pay them.

It's a start but theres no limit for me on where I would like to invest.

It seems that some buyers might like having a condo with open spaces that are limited common areas they can call their own.
