You will still have an electric bill even if tenants pay their own unit.

Start with house hacking, invest in credit and education, and leverage electrical skills.

In my first stint in real estate, I thought reinvesting in the business was keeping the marketing engine running.

@Ori Skloot can you give more details on the electrical and plumbing work you did?

Ask the planning group to look at another subdivision plans and also ask the engineering firm for a similar set of plans to look through.  

Utility Costs (Water, Gas, Electricity):- Paid monthly by the tenant unless included in rent.

if the electrical needs to be updated, that is OK as long as that is factored into the numbers, and as long as you have someone competent to do it.  

But larger repair items such as appliances and mechanical, plumbing, electrical, roof windows doors etc should still fall under the landlord's responsibility.

You would want to check local zoning to make sure you could build more than one as a lot goes into that beyond just being close to plumbing, electric, and gas.When you mention "a lot goes into that beyond just being close to plumbing, electric, and gas," what are the top things people tend to overlook when preparing to build ADUs?

Imagine you bought a property for $2M.The land (excluding any structures) is valued at $400K.Since land is not depreciable in the eyes of the IRS, we subtract the land value from your purchase price to get your depreciable basis.Your depreciable basis is simply where a cost seg engineer starts from when allocating your eligible assets into either 5, 7, or 15 year property.In the scenario above, your starting basis would be $1.6M since your basis = your purchase price - the land value.Having an accurate land value is essential to getting your depreciation/bonus depreciation calculations right.This is the starting point for any cost seg study that you do.
