We have been keeping our eyes and ears out there for the past year. 

It seems now we have a bull market and if it starts going the other way I would like my rental to at least continue to produce monthly cashflow...that's where I'm at now...still researching and seeing my options... $46,800/year in cash flow with $500k is a nice yield at 9.36% ($46,800/$500,000).

You should consult with local property managers and find what the average DOM would be to lease your home and rental rates etc. this would be a good starting point. 

I’m just trying to figure out where to start in terms of figuring out what makes sense.

Start with the end in mind --- what would be the investor's exit strategy for this home? 

Start by attending real estate meetups, BiggerPockets forums, and local investor groups to connect with potential partners.

@Krista Lance, I would say with 7 properties that its a good time to start thinking about bookkeeping software.

So I'm interested in getting started in purchasing and running self storage facilities and want to learn more.

I ask why and they say "well I did not know my grandpop was going to die" and right when they say that usually they start to understand.Correct.
