@Anade DavisHi Anade, You’re on the right track with reaching out to your survey and engineering company—they often have strong connections to local contractors.

Electric: is the easiest to split, but may require holes cut in walls to separate the units.Gas: gas lines aren't as flexible as wires, but it can usually be done affordably.Water: most cities will NOT install additional water meters on a property.

Get a degree in Finance or Engineering and you'll graduate with a world of possibilities. 

Overcrowding can strain plumbing, electrical systems, and air conditioning, leading to expensive maintenance issues.

However, these properties generally have a lot of land improvements that qualify as well as certain portions of electrical, mechanical and plumbing that can qualify.

Next time I'll start with the engineer.  

It's a big money maker for architects, engineers, and contractors, but not a huge opportunity for investors, nor should it be. 

I found it but reverse engine my own search.

These methods include: Detailed Engineering Cost ApproachDetailed Engineering Cost Estimate ApproachSurvey or Letter ApproachResidual Estimation ApproachSampling or Modeling ApproachExperience or “Rule of Thumb” ApproachIt’s important to understand the differences between the approaches including which one best fits your property and the reliability of each approach.DETAILED ENGINEERING COST APPROACHThis approach compiles the costs from construction and accounting reports to build a report.

I can search it but same deal, the search engines don't evaluate the results.
