Research all four seasons before you buy.
It's a good idea to visit the area in which you plan to buy during every season. Though the hiking may be great, the roads may be impassible for part of the year. Or the beach may be beautiful during the peak of summer, but as winter approaches, the area may be plagued by the smell of fish.
By renting houses in different parts of the community during different times of the year, you're ensuring that you know how the community fares as the calendar unfolds. If you're gung-ho on the idea of renting the house to make money, you need to be able to collect those rental fees for as much of the year as possible.
