If you plan to rent your investment property out, single family homes are the easiest homes to rent, assuming they're not too expensive.
If time is taken and a valuable deal made, the property will produce a profit stream and steady rent increases for years to come.
When house values increase, especially as dramatically as in recent months - people feel freer to spend from the wealth they have, or the wealth they perceive they have.
What type of property suits your lifestyle?
