Hi Tim,
The truth is, not all homes make good rentals. If your property does not cash flow and might even give you a negative cash flow, then I would pull your money out and invest in something that does cash flow and hopefully appreciates.
Often times renting out your primary residence has a major advantage because you get to keep your ridiculously low interested rate, I am assuming 4%, compared to purchasing a home as an investment property with a 7%-8% interest rate. The fact that you still won't cash flow even with your current interest rate shows how bad the rental market is for your specific property.
There is probably too many rentals like your OR there is just no demand for a rental like yours there. I know in Arlington there are a lot of large luxury condo units you will be competing with. Because there are so many of them, they can afford to cut their rental prices to compete. There are literally thousands of condos in Arlington and more and more are still being built.
You also have to ask yourself what your goal is right now. Are you trying to get consistent passive income in which case cash flow will be your primary goal or are you wanting to keep this as part of your retirement plan and expect it to appreciate next 20 years? For me personally, I am trying to get to a place where I cash flow $5,000 a month and that dictates how I currently invest.
If you will net $100K after the sale and you can get an investment loan with 80% LTV then you can purchase around a $500K investment property. I would start looking at some potential properties and crunching numbers. I am confident you could find some that will both cashflow positive AND you think will appreciate in value.
I hope this helped, good luck
