When I crunched all the numbers it seemed like a good investment until I put in an average monthly water/sewer bill of 800-1000, which tanked my COC return down to roughly 5%.

I have been trying to crunch the numbers over and over to see what works better. 

I'm not into house flipping, but rather buy and hold for cashflow, thus whether the markets go up or down, as long as there are people needing a place to live, my investments should be safe and they are backed by insurance, which is more than I can say for anything I put in a stock market.I do have an interest in doing some partnerships and have been looking into that possibility in the future, I am very analytical and like doing the property analysis and crunching numbers, however I have no desire to get into the rehab/swinging a hammer side of things so the biggest value I can bring to a partnership is generally being the "lender" or analyzing deals.  

And with the numbers I quickly crunched, it should be a decent amount. 

However, I am on a time crunch since we need to re-locate in 3 months.

****By tested I mean, I get a number from the spread sheet, put an offer in on a house, and then the loan adviser tells me what my payments will be...including P&I, Insurance, and Taxes...if my numbers don't hit to the penny...I MADE A MISTAKE AND NEED TO FIND OUT WHY.There's an arrogance to running your own numbers, you have to KNOW you are right, and then obsessively crunch to find out why you're not.I look at my spreadsheets every day and ask how I F'd this up.

No sense in crunching numbers on properties that no one is replying on

Seems like any way I crunch the numbers, most of these deals are turning out to be at least somewhat profitable.

I am a noob here and starting to learn about Real Estate Investing in Rental Properties, and had a couple of questions on how people typically crunch their numbers when analyzing a deal.I watched a replay webinar from BiggerPockets here and saw that when using the Rental Property calcualtor on the site, they usually calcluate in Vacancy, Repairs, and CapEx into the expenses.I am reading that people usually aim for 12% or more CC ROI and that would be considered a good deal.
