Also a single software license and team for management could be used. 

It's a single family home at south FL, purchased with all cash, free and clear, rented out. 

That would be your best bet. 

I think you best bet It's to find a duplex to investing in house hack

If it's the other way around, you may have to wait, start smaller with a single family that you can BRRRR with a bigger down payment then cash out quickly to do it again until you can go bigger.

I would bet that the majority of people who fear market fluctuations are people who are not at all, or very little invested in the market.

You have to watch out for the Single Family Homes that are zoned as SFR but being marketed as Multi Family.  

I have a duplex on a single meter and rent to B grade tenants.

I am currently in the process of getting a HELOC for 50% of the value which seems to be the max amount Texas laws allow for a single cash out loan (or so Ive been told!) 

Even for the most basic of zoning, T3/single family, the lot size minimum always says 5000 sq ft.I've tried emailing and calling the zoning department numerous times and they have never gotten back to me.
