If I did have an opportunity, where do I start and how do I raise funds for it?

Once you have a shortlist, sign up for an account with each one and test them extensively to see how they function.

However, there is a nice marketing aspect to "only pay for what you use" because if there are heavy utility users in a building, it essentially gets subsidized by all residents over time.I'm lining up some meters for testing and will report back on any findings.

If I buy this property and the money comes from someone else's account, will that raise any red flags within the IRS systems?

My only real turnover has come from needing to raise rents to market value.

@Collin Schwartz so assuming an average $40k per door, that 1st 25 doors was ~$800k, you must have raised somewhere in the area of $200k cash of your own? 

First, you take the hours required by your state and then the in-class test and then the real state test.

Having "real estate investing" or "real estate" anything, in your LLC name will surely raise red flags for banks, especially as you move beyond net 30 accounts to larger credit lines.
