If you decide to do this, my advice would be to make a parttime job of it.
Buy 4 or 5 smaller and cheaper units in good downtown locations, or near large universities etc, that are empty and need renovating, rather than 1 or 2 expensive one that have 3 bedrooms.
Renovating is cheap here. A fresh coat of paint and new modern lighting doubles the price, as they say.
Focus on different markets.
Be on hand and stay on top of what's happening in each, not just getting a rental agent to take over etc.
