Make minimum payments on all props but one, devote alllll the cash flow from the entire portfolio to paying down that one loan as quickly as possible until it's free and clear, then move onto the next.

It can be done, but you have to devote the time to it. 

I didn't have the time to devote to real estate when I had a full time job either, so passive multifamily worked for me.

The first step is to determine how much time you can devote to real estate investing: it will help you narrow your focus to either passive or active RE investing.

I've been devoting most of my free time learning as much as I can in general business and real estate. 

I am really devoted to learn all I can this year and build the connections needed to make a good investment next year.

I do feel if I hadn’t devoted a larger percentage to real estate these past two years I wouldn’t be about half way to attaining financial freedom.

We both have some time outside of our primary careers, which we devote to real estate investing.

If you don't need the income, the just devote all the net cash flow to paying down the properties more quickly - you'd be surprised how quickly that snowball builds up and how quickly you can have free and clear properties under your belt. 

The only thing I'd do differently is devote more time to this deal (and maybe let some other deals go) when I was going through everything.
