Coming to this post a bit late. None of the comments I've read seem to address the solution that seems quite obvious to me....
It sounds like you have a bunch of equity, negative cashflow, and a big headache from all the rentals. If your goal is just to replace a good part of your W-2 income, then why not rotate that pile of equity into a CASH DEAL. Of course your tradeoff is leverage, ROI, and tax write-offs; but again, if your goal is just to replace your current income it seems like a no-brainer to me. Especially if you lack the skills or time to do value-add deals or find better priced off market deals.
I think so many people discount the *psychological effect* of financial independence. Cashflow can allow you to establish a new baseline for how you make money from working. What I mean by that is, take some time off from working, live your life on your own terms for a while; and then when you become bored with golf, beaches, and hiking all day you can start looking into a new (less stressful) career. Perhaps that means pursuing art, consulting, teaching, etc.
Whatever it is, removing the stress of making ends meet can open up doors that may even be more profitable and/or rewarding than your W-2 was.
