@Michele B. took the words right out of my mouth. Why does only one property cash flow, and if the goal is to replace a salary, how do those non-cash flowing properties help meet that goal?
Quick story on me, I became an accidental/on-purpose landlord with my first home purchase. I rented out my bachelor pad after my wife and I purchased our "forever home" and it never cash flowed. For me, it was about having a property that would gain traction in the market. But the property would never do that because of its design and limitations, so in order to make money, I'd have to either create more space/more bedrooms, or wait for the area to improve. Neither happened, I sold it, and found a property that should net me cash flow return of 8-10% per year, conservatively. It isn't a home run, but it cash flows even at a conservative underwriting level.
Being unsure of your next move is never OK, in my opinion. It tells me that your plan isn't set, so you're a wayward ship right now. I was in that rut for a couple of years, so learn from my mistake. Set the goal(s), and then compare your current spot to your goals and find the gap. Once I did that, it became clear my bachelor pad was never going to cash flow, and I was better selling it, taking the proceeds, and buying something that will cash flow.
Also compare your goals to your area -- I live in Philadelphia where unless you get properties at a discount, or off-market, you are buying at a premium, and are banking on major appreciations in the regional real estate market (which in Philly, can happen on a block-to-block basis) which are not a given. Thus investing locally for me only makes sense if its in line with my goal of cash flow, to help bring me closer to the next property.
If your goal is cash flow to retire, you've got 66% of your business giving you the middle finger on that goal right now. Figure out how to make it profitable, or dump it.
