Is a 30% cash on cash return sustainable on a 170k investment?

[Michael Kiley]

Here's my plan:

I want to be financially independent by selling my personal residence and investing the proceeds to pay my living expenses.

If I net 180k from the sale and use 10k toward the downpayment on my next residence, I'll have 170k left to invest. If I invest the 170k with a 30% cash on cash return, I'd reach my FI goal. Cleveland is an easy place to find deals that cash flow but is this realistic and if so, any advice on how I would go about this would be very much appreciated. To this point, most of my experience has been with single family houses and a duplex but would consider larger multi unit property's if I could get the financing and the numbers work. Thank you for your help!
