Thanks for your email. Deciding to remove a pool or not should be a decision made, as Marcy noted below, with an eye toward the desires of the general real estate buying public in your local area. Sometimes a pool adds value to a home, and sometimes, as up here in No. California, a pool can be perceived more as a liability and nuisance than a benefit.
Having removed pools from homes in the past, I do want to caution that you will not be able to simply "fill in" the pool, but must remove the pool equipment, concrete (if older) or fiberglass liner, and all of the plumbing lines leading to and from the pool. The cost can be almost as expensive as repairing the pool, so the trade-off between pool and no-pool may not result in any cost savings.
Speak with a pool company in your area or with a qualified Realtor to determine if pools add value to homes in the warmer climes of Encinatas.
