pros: 
1. building equity - over time, the value of your house is likely to go up, allowing you to make money off your investment. 
2. lower transport costs - it is often cheaper in the long run to own a house than to rent and live in the same area. 

cons:
1. maintenance costs - homeowners are responsible for any repairs or maintenance costs that come up, which can be costly. 
2. difficulty relocation - selling a house can be difficult if you have to move, especially if there is a down market.
