I'm particularly looking for information on Utilities, Internet for a 4-bedroom property.

That leaves the low property tax, no income tax, cheap utilities, no weather related expenses, tile roofed, stucco sided, median property age under 20 years, cheap insurance and solid foundations Las Vegas properties with lots of entertainment, very cheap flights and a good quality of life. 

The power and all other utilities are off, grass not cut (we had it cut twice) and cobwebs are covering all points of entry.

You should utilize leveraging when you are planning to buy multiple properties, since you will have a much greater cash flow (if done correctly) with multiple properties (even if you have a mortgage on all the properties) than having one property with no mortgage. 

We then utilized his actual paid Cost Segregation analysis.

It certainly takes some time to get the experience, but once you do, utilizing the leverage from the bank and from other people allows for great returns.  

Who's going to go to all the bother of building an ADU unless it at least covers your substantial taxes, insurance, and utilities on your main house? 

We have set a goal of getting 4 properties in the first 4 years after graduation by utilizing low money down options, living in the property for 1 year and moving on to the next.

Find out who pays which utilities (landlord or tenant), etc.Make sense? 

On a larger park, I would recommend a formal cost segregation study for this, but an 8 unit park is too small for that to make sense, so you can also assign a value in the bill of sale to include:Landscaping shrubbery & trees: 35 mature trees approx. 20’ tall each, pool equipment, roads: XXX square yards of asphalt paving, sidewalk and curbing, electrical pedestals, concrete pads, underground utilities for electric, sewer or septic, pool, clubhouse, etc.
