Having 7 projects going on myself in the Pinellas county market, I'm beginning to see a slight drop-off in home values but the demand remains.

I really like the notion of collecting remaining deposits over time in the form of installments if need be.

If the property is cashflow negative according to one, it'll remain cashflow negative when the exact same numbers are transposed onto the exact same spots on a new form, that contains the exact same math. 

I'd like to sell one of them through a 1031 exchange, and use the proceeds, to purchase the second one so that I will own it free and clear, and use remaining to put a down payment on a to be determined multi family.

A relative (more than likely) has passed and real estate remains as part of their estate. 

Or if rates remain high/or creep up more, you have a peace of mind being on a 30 year term at a fixed rateBut what's the goal here?

Remaining three are...DallasPhoenixHouston

If the dollar was to fail would the investments you make today remain sound in an uncertain future?

Now, we are in the demolition phase of the project which I predict another 80,000 in the remaining remodeling expenses.

This also seems unlikely and far out, as supply chain issues continue to persist, build times remain extended, and material costs remain elevated.
