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.

Look at factors like proximity to jobs, schools, transportation hubs, etc.

That should really be the deciding factor...is it necessary and a large enough project to include the permit process?

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. 

@Dennis Bragg, how did you factor improvements and market appreciation into the buy-back price?

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

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

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

You have to factor in demand and vacancy rates to determine if it will be more profitable, and that’s specific for each market.

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.
