In time I could have safely weeded out the bad apples who may have been of a violent disposition, but I'm not sure the juice was worth the squeeze.

I live 40 miles away, so I called the owner of the biggest plumbing co in the city and he and 2 techs dropped everything to get to the property within 10 minutes of my call.I had put a garage outdoor access remote on the outside of the house.. they couldn't get in thru that because THE POWER WAS NOW OFF.Luckily i had put a coded door knob on the kitchen door that opens to the deck-- i gave them the code and they were inside instantly.The water heater was STILL SPEWING WATER full blast in a stream so strong it was hitting the second story ceiling and hitting the ELECTRICAL PANEL also located in the garage and that's what had knocked out the power .The plumbers immediately turned off the inside water main cutoffand sent me photos of the EMERGENCY SITUATION the pm so calmly let me know about by email an hour earlier.i fired the pm co that instant and got on the phone to STATE FARM (my HOMEOWNERS/rental policy dwelling ins co) all whiledriving an hour to the property.i also called the city's best WATER EMERGENCY REMEDIATION COMpany while en route.When i got there, the water was turned off ( finally)the drywall ceiling had fallen in, the light fixtures destroyed, the garage door opener plastic case was HALF FULL OF WATER and there were 1000s of mold blooms on every surface and hundreds of stacks of spiky growing black mold (looked like iron fiilings we used to play with in that game we all had as kids where u use a magnet and drag the iron filings around to put hair and a mustache on the bald guy cartoon photo) the mold spikes were 1.5" tall on the wood railings and stairs going into the house, on all of my beautiful built in wooden garage shelves--- what a mess-- like the streets of Beirut after the bombs went off.and I don't have allergies -- but i could not even STAND inside the garage because the WET MOLD MILDEW SMELL was so strong it instantly gagged me and gave me a headache and i couldn't breathe.So here we are on Jan 17 and now i know that the BEST rental dwelling policy does NOT COVER MOLD REMEDIATION AT ALL ( so far $14,000) but it does cover water damage with a $2500 deductible...

To be as apples-apples as possible, what sort of rent roll would you get with existing housing for that investment size? 

Homes also go out of foreclosure so it might be a little challenging for a first bite at the apple.

I would prefer to not live in the cities around Minneapolis being that I work in apple valley and would not want to add time to my commute which would give me less time to work on a given property.

I don't compare our properties or strategies to anyone else, because it's not apples to apples.    

Come up with the closest apples to apples example you can come up with.  

I read the secrets of the millionaire mind, followed some of the steps, ended up saying I was a money magnet, came across a nickel, said I was a money magnet, customer gave me 120 dollars, said it again and my monther in law is gifting us 40k to buy a house.

In the days before the internet  & instant credit checks and background info at your finger tips, a few bad apples were able to fly under the radar, not so much anymore, thank God!    

Thus you'd need to adjust for both risk and for active management (time) to make somewhat of an apple-to-apples comparison.
