I would use as many of the actual numbers from the property that you can find, but beware that some numbers may be missing or edited to make them look better, so you should have a rough percentage that you use for your calculations.  

Yes, i am looking for long term hold and rents, i dont have enough experience in rehabbing to do a flip yet, due to my physical limitations from my military days, i am striding to increase my passive income to a point i can comfortably live the rest of my life on.In regards to the %, i have no clue, i have gotten multiple comments to just go by the percentages.... with no additional details.

RUBS is a Ration Utility billing system that allocates 100% of the property's utility bill to the residents based on an occupant factor, square footage or a combination of both, less a predetermined percentage of a common area allowance.To put it in easy words, you still pay, but are able to bill back to tenants. 

He suggested a Partnership called "Tenants in Common" as a way that you keep control no matter what you contribute on a property's price and have different agreements with all Partners regardless of their percentage of their contribution of the purchase price.Whatever you do just be careful, understand it, and feel good about the Partnership or anything put in writing that's a business liability of your personal involvement or responsibility whether it's monetary or not.Good luck to you!
