To buy more or Not to buy more that is the question

[JJ Cole]

OK, Here is here I stand:

I own 12 SFRs, have loans on 4, bought the other 8 cash. Captured anywhere from $25K - $45K in equity going in on 10 of them. Good areas and schools, no war zones; solid C and a few B neighborhoods. Typical rent to purchase price+rehab ratio is between 1.3-1.6%. Have a couple of lenders willing to give me 6 cash out refi loans. I was planning on taking those and then trying to buy 6-10 more houses to get to 20-22 houses. Then I read on the forum that many a investor has gotten over leveraged and gone bust.......and now I am wondering whether I should reconsider?
