irongarment: It's an easy calculation to make. Take your capital cost of the house, take your income from rent for the year and deduct your expenses for the year. This lets you calculate a percentage return where the value of the house is the principal, and the net income from rent is the 'interest'. Now compare that to a term deposit with that amount of capital for a year...
That's one (simplistic) calculation you can make....
However 100% equity in one house may enable you to borrow on up to 5x more so factoring in deductions on interest, maintenance etc and attributing losses as I mentioned above it becomes a whole different (and attractive) equation if you want to get into the game properly.
The ability to access finance on property (leverage) is part of what makes it so attractive - in addition to the tax treatment (negative gearing).

Only if you sell it - however there are plenty of ways to realise capital value from your investment without disposing of it (borrowing against it, inheritance to your family, holding it in trust etc).
