While I’ve seen QuickBooks mentioned in forums, it tends to be more expensive and seems better suited for larger portfolios.

Even with all I mentioned and forgot to mention above the real estate money was easy moneyHere is the house https://www.corcoran.com/nyc/Listings/Display/4778829?

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.

Some of those included those previously mentioned windows.  

People mentioned master lease so are they essentially arbitraging the unit?

You mentioned you might be doing something like that.

I like how Nathan mentioned that most social media stuff is inflated.

What happened with the young couple you mentioned invested with them 

The numbers you mention in your post are confusing - like $150k annual income from a rental property.  

Quote from @Jack Townsend: I heard David Greene mention a loan product that only requires a 10% down payment on the purchase price and 10% of the rehab budget.
