I don't follow -- how do you have over $1M in properties that generate only $5K in profit every year? Is that a typo? That seems to be a ridiculously low rate of return. It's not just that you've got all your cash tied up -- it's how much you are losing from not being able to dedicate that cash to other investments that would make you more $. Your annual income from these investments looks to be less than 1%, which is about what you could get from a bank account. By comparison, if your @$700K ($600K in equity + $100K in cash) were invested in the stock market, the 4% rule says you could draw $28K from that every year. I am guessing that you are banking on long-term appreciation and improved cash flow once the mortgages are paid off. But you are also very concentrated in a single market, which really increases your risk (that's like me putting all my money in GE or Coca-Cola instead of a broad market index fund).
I am not at all averse to using rental properties as a path to FIRE -- there are a bunch of people here who have done that very, very successfully. It's one of the few ways individuals can use leverage without putting their entire financial base at risk. But the people who do this successfully are not simply crossing their fingers and hoping that a particular market appreciates -- they focus on properties that throw off a good income, so they can take that income and either buy more properties (in the early years) or live off of (once the income stream = annual expenses). They still get the benefit of having the tenant pay the mortgage, with the significant increase in cash flow once those mortgages are paid off -- and if the value goes up over time, that's just a bonus, not something they are relying on to make the investment successful.
Is there a way that you can swap those properties for better income producers without triggering capital gains? I know in the US you can swap out one rental property for another and defer the capital gains (Starker exchange), but I don't know if you have anything comparable. If you have $600K in equity + another $100K in cash, that would go a long, long way toward a bunch of other properties that could give you far more income. In general, I would suggest doing some research into property investing as a business vs. the "seemed like a good idea" approach (not a criticism -- that's where we all start!), so you can learn how to do the financial analysis for what makes a good rental. Once you have that solid grounding, you can look for better opportunities to put your massive equity into properties that will generate more cash and support you now *and* in the future.
