Your designer then will walk the property and they create a scope of work with materials, what to change, and what to update (electric, HVAC, plumbing, etc).

You can find an 18-guage NOMA rated low voltage 2 (3, or 4 wire if you want to pull multiple connections in a single run) in 50, 100 and 500' spools at any big box (HD) or HVAC/electrical supplier.

I kinda like it, I would however maybe permanently block the fireplace, by putting a cheap electric unit in the fire box, unless you dont mind if the tenant burn it down. 

It does not have a connection to the water/electrical grid.  

Say I find a deal, they work their asses off on renovation either on the weekends or taking one or two weeks vacation, we hire out electrical and whatever else should be hired out, and they raise at least a good chunk of the capital perhaps from family, bosses, their dentist, etc.

Finish electrical and plumbing.

I have some tenants that moved in on April 1 with a 6 month contract.. they paid good up until now and their phones and electricity have been shut off for about 2 weeks.

If it's not truly zoned multi, you'd need to do "all bills paid" - you wouldn't be able to get separate electric, water and gas meters.

Another bucket contains electrical parts.

Removal of a non load bearing wall will not cost much at all, especially if you already have a dumpster on site for your remodel assuming you are rehabbing the whole house.The size of the wall and how much electrical or plumbing is inside will also have a factor in price.
