There is only one electric and gas for all the tenants.

No, because they have cable to pay, they have electric to pay, food to eat, going out to do, purses to buy.

I do plumbing, electrical, basic framing etc. the only things I would contract out were siding, roof, windows, HVAC.

I was thinking of adding an electric garage door opener.

@Julie HavemanI am going to have to add utilities to the tenants payment (only 1 water heater, furnace and electric). 

HI I purchased a home in a multi unit (R4), high density zone.I am currently renting the house cash flow is just $50 after mortgage payment.This house has a big workshop in the back with a high rise ceiling, brand new roof, electricity and water.It sets in a half an acre lot so I am able to rent the workshop and land for $700 a month Total cash flow on this property is $750 a monthI'd like to enclosed this workshop (it has 3 brick walls already built) and make it into a livable place.I can still rent the land and keep the cash flow at about the same amount ($700).However there's no sewer  at this house just 2 septic tanks attached to the main house.Workshop will need:windowsanother walldoorscooling and heating systemBathroom etc...I can build build more units attached to the current workshop since there's so much land to play with but i have no idea of the cost.I purchased this home for $150k in 2016I owe 143Klast month I paid for an appraisal and the current value is at $185(flooring was the only improvement at the house).Question is should I refinance and bring in sewer line, build more units or live it the way it is?

From ceilings fans, dishwashers, HVAC units, electrical outlets, and basically everything under the roof, I highly recommend it.I hope this was helpful,@Charles Kennedy

(Everyone seems to think this, not just you.)Here's a page from Cleveland Tenant Rights saying the landlord can require the tenant to pay water as long as it's separately metered: http://www.clevelandtenants.org/for-tenants/tenant...Here's a page from Garfield Heights specifically, saying the same thing: https://www.ghmc.org/renting/renting-basics/rights...You must supply water, but you also must supply heat and electricity.

I have both electrical/carpentry/wood flooring experience.

The property is a triplex, converted out of an old house that's been taken care of very well (as far as I can see without a building inspector), so the water and gas are not split out into separate meters for the tenants (electrical is).In order to make this deal work, I'd love to figure out a way to invoice the tenants for those utilities.
