Thank you for the reply’s.Currently have 2 Boilers, as well as the basement heater pictured.3 Water heaters2 gas meters2 100amp electrical panelsCurrently 2nd Floor, Basement and Garage are all on same electric and gas.Considering separating the 2nd floor and basement by adding 3rd gas meter for basement heater and eventual stove, add 3rd meter and 100amp electrical panel.This way I’ll only pay for 1 Unit electrical (Unit, Laundry, Garage, Common areas).

As @Holly Kaufman noted, a SF with garage unit or mother-daughter is much better so the spaces can be separated.

Just is...I do think you would have had better odds if each property had been separately priced and contracted considering that's how you're financing the acquisition.

I can’t take credit, mostly dumb luck.Not enough space to go into all the details but we closed on a duplex in November 2018 (units 6-7), a SFH in November 2018 (unit 8), a 3 duplex deal in February 2019 (units 9-14), two separate duplex deals in August 2019 (units 15-18), and a 2 townhouse buildings (4 units) deal closed in October 2019 (units 19-22).

It is a two unit , with the upper floor being a separate apartment that is part of the renovation.   

For this purpose, each interest you have in a rental real estate activity is a separate activity, unless you choose to treat all interests in rental real estate activities as one activity.

If it is a single meter and you have tiered electricity rates that electric bill would be significantly more expensive than for 3 families in 3 separately metered units.

I plan to open a separate checking account just for my SBA funds follow the rules and keep good records just in case..

That said- I’d love to hear the pros and cons of putting all properties into one LLC vs. each individual property being in its own separate LLC.Any insight would be greatly appreciated!

If all of these incomes are hitting your personal returns then that's one situation, and if they occur on separate returns that's a different one.
