One thing that I’m seeing it that large multi unit buildings beyond the 800k mark are all on a boiler and paying to heat the entire building ruins the numbers.

Just factor the cost into the rent.

Build your credit.

Quote from @Eric James: I'll continue the strategy I've been using for the last 2-3 years, building small apartment buildings.

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.

Financing is important but your realtor will absolutely be the determining factor whether you purchase correctly or not. 

Due to recent building code changes, you can build a framed building up to 4 stories on a slab, which significantly reduces the overall cost of new construction.

Meanwhile, the sellers who are most likely to offer creative financing are normally the owners of  real estate that have issues.....condition.....low barrier/over supply market......or perhaps pricing issue, and one of these factors is why its not marketable in a arms length transaction and why creative financing would be accepted.

If saving 20% and building direct is worth it to you I'd recommend it.

I was recently exploring a two-story commercial building for sale on a corner in a growing downtown area.
