For instance, last year I had a 40' section of Orangeberg sewer line that needed to be replaced under the driveway.

Trust that voice in your head @Bradley Perry.

So for instance, lets say the mortgage is $3400 flat and that split amongst 5 people would be $680 but I was thinking about raising the price per person to $750. 750x4(roommates excluding me)=$3000 leading me to only pay 400$ month compared to paying the full $3400 by myself.

Thanks for the heads up, Brook.

Still, I'll admit I may have just been excited to jump in head first and start talking to people!

Here’s why: after 12 months the actual cash invested that you use in the formula to calculate the ROI will be changing as the loan is paid down, or when property improvements and repairs are made.The main issue with CoC as a metric, is that it doesn’t take into consideration the time value of money; so if, for instance, you invested $1M in two deals and received $100,000 back (in addition to your initial investment), but in investment #1 you got the money back after 3 years while in investment #2 it took you 10 years to make the same profit — CoC will still be identical, even though it’s clear that investment #1 is better.As a metric for a potential investment, you’re probably wondering what a “good:” cash-on-cash return would be.

I look forward to diving in head-first!

My goal is finding a property in the South Carolina area, within an hour of Hilton Head Island. 

Thanks for the heads up!

I'm noticing a big influx of people moving out of California and heading to Phoenix, Texas, Colorado, Boise, and various mid west cities.
