it adds value in the same way one would value a pair of cowboy boots.
If you like cowboy boots...you see the value.
Selling a pool to citizens who live in sub-tropical climates like TX and FL is not rocket science.
If a person can not see the value the only response you should have is, "This homes not for you!"
If you and those important to you will ENJOY the pool, that is the ROI you really want.
Best of success,
