I like house and I would like to buy a new one 
The only downside could be, if you buy a house with a pool your house becomes the hang out
not really, I don't want to party much so I want to have pool so I can swim and relax during summer
There is nothing quite as relaxing as a pool in your backyard!!  Just make sure you acknowledge pool safet
yeah, that is my concern too, plus i will have to clean it regularly. But I want to rent out my house as well so I will have some extra money to cover the maintenance. 
Having a pool would certainly add appeal to your home for some renters.
right, beside pool, I am looking into house with large backyard because i want to have a garden. 
You would have to think about what you would want to grow
I want to grow fruit trees and vegetable, I have been thinking about sustaining myself with my own grown vegetable.  
Having an apple tree would be great!
