Cash on hand, where to put it?

[Matt Crow]

Ok, so we're relatively new to this, but not complete newbies. We have 4 single family rentals that we've acquired over the last 7 years.

We're currently reading the books promoted on this site, and making our way through the podcasts but I have a couple of quick "what would you have done" questions for the pros on here.

Our 10 year plan is to have 15-20K/month in income after expenses. We're interested in more single family rentals, flipping, multi families, and possibly commercial.

We'd like to have a well diversified portfolio so my question is for the long termer's here:

If you had the same goals, where would you put $50K cash to start that process? What about 100K? Would the starting point change or stay the same?

We're just looking for the best possible place to start our hard work!
