How common for bank to call your loan if you deed property to LLC?

Now, it's slowly to become a common occurrence.I'm trying to get an idea of which route I should possibly take.I was thinking about starting a we buy houses website for here,  OR buy a piece of land (which is quite expensive now) and slowly build apartments on it (many places only zone for 3+1 so 3 apartments plus penthouse)Just looking for some advice or even your own personal suggestions on how you would go about something like this and getting your feet wet.

Residents pay all utilities as of now and commercial pays own water as well.

The only space that would be practical would be on the 1st floor, which is all common space. 

I have many clients who are utilizing credit lines on the coast and other markets and coming to my market and buying and renovating dogs etc.

I spotted a 3 units home, each is seperate building and has seperate utilities. 

That is the most common play in these type parks. 

You can then adjust expenses based on a few factors:  does LL pay utilities or tenants? 

The renter pays taxes and utilities.

Do all units have separate utilities?
