I am a water person and have owned two homes with pools. My current home only has a hot tub and when I move, my next home will have a pool. As such, I would be a home buyer who is looking for a home with an existing pool, or i I would settle for a home without a pool if the lot is perfectly situated for a pool. When I sold both my previous homes, the realtor, who didn't understand the mentality of pool owners, told me that people would not want to pay more for a pool, or would try to make me drop the price because of the pool, or since one of my homes was being sold in the winter, wanted me to put 10k in escrow in case the pool wasn't functional come spring. I said No, no, NO! I was not selling the home to the dozens of people who didn't want a pool. I was selling the pool to one person who absolutely wanted the pool and was willing to buy the pool at a fraction of the cost of installing a new pool.
In answer to the question, a house without a pool "may" sell quicker than a house with a pool at a same price to someone who doesn't especially want the pool, but given time a house with a pool will sell to a pool oriented buyer at a higher price.
