It is common for the average investor to want to buy an investment property not too far from where they live. There are many reasons for this, one being convenience and another being a sense of security of being able to drive past their investment now and then.
That’s not a bad thing and I’ve certainly done this myself.
But just because you may have more knowledge of your local market, does not mean it’s a good place to invest. Just because you want to (or need to) live in that area that does not mean other people want to as well.
