One of the biggest factors in successful flips is building a strong team: contractors, agents, lenders, and property managers. 

The rise in home equity over the years can be credited to two key factors:1.

Flipping a brand new home likely wouldn’t bring much profit - especially after having to close twice when you first buy it, and later sell it.Maybe you have millions to spend and I’m just missing the big picture… but when I think of “income” I’m usually thinking “net income” after you factor in expenses, like purchase price or building costs?  

Rate will be highly dependent on loan size, credit score, LTV, location, and property type, as well as a few other factors.

In your situation there is actually another factor that may work in your favor.Only the proceeds allocated to the sale of the building can be used in a 1031exchange. 

There are more factors than just the community (#beds, level of theming, location to the amenities, style of home (single family, townhome, condo) and others) But I would strongly advise to stay within some of the same communities you mentioned like Storey Lake, Windsor Hills, Championsgate and a few others if cash flow is your goal.

Will depend on several factors like the type of property, type of tenants, your risk tolerance, other assets you own, your estate planning, laws where the property is located, etc.

With that being said, the interest rate is going to be the single biggest determining factor for whether you're barely breaking even, or seeing a decent monthly cash flow.

You will also have to factor in the closing cost for the new loan.

If you're considering house hacking a multi family property, some lenders might be able to factor in potential rental income to help you qualify.
