Swimming pools in rentals?

[Kathrine Pomeroy]

Hi Friends,

What are the pros and cons of having a rental house with a swimming pool?  I know they don't necessarily add value to a house, but do they add value as a rental?  Is the liability not worth it?  Is the upkeep not worth it?  Does landlord or tenant maintain the pool?  Or do you hire a pool service and roll it into the rent?  It is a plus in desert areas like Las Vegas or Phoenix?  

Thank you for your input!
