had great success with rentals over 15 years, but I don't self manage (use a property manager @6% fee). I do know that your success depends largely on the area where your properties are, and the industry in the area, etc.

I saw on the news one night the SWAT team forced entry in a house, and realized it was one of ours. They had to force entry in full on gear in all doors because a tenant was holding his GF at gunpoint, high on drugs and wouldn't let her out of the house while she was on 911 asking for help. He fired off a round so an electrician had to come out and inspect the property before the power could be turned back on. $4,000 in damages that I had to eat when we did a 48 hour eviction and had to repair everything...

In general though they have been great and build a ton of equity each month.

Yep. I own 30 houses from this strategy. Also used a LOC on some paid for to buy more and pay it off with rents.

Nope on my nearly 100 doors I wont rent to anyone on government assistance/section 8. Not worth the hassle dealing with the government nonsense and these people damage more properties as a rule then the others.
