When we were preparing to sell our house, we did a lot to fix it up; removed wall paper in kitchen and textured and painted there, touched up or repainted bedrooms and closets, cleaned the flowerbeds and added fresh mulch. The realtor told us to replace knobs and handles in the kitchen, that no one wanted brass knobs it had to be nickel. She also suggested fresh carpet in the den.
The people who bought the house didn't care about the paint, they had painters come in and paint all the rooms white. The pulled the carpet and installed wood floors in the den. They didn't care about the kitchen cabinet knobs nor the 20 year old mini blinds. They wanted that location and the floor plan. All the things that we thought were so special about our house, the ethernet wiring, surround sound in so many rooms, outdoor speakers for the deck and the small fish pond and fountain, the carefully constructed landscaping that made such nice views out of every window -- they didn't care about any of that. They put up curtains and kept them closed, ignoring the views. They never went outside to the deck and took down all the hanging plants and flowers. They sold off the fish pond and fountain. They let us take the outdoor speakers since they'd never use them. I'm glad we had already taken the surround sound speakers down.
You can never tell what will matter to the buyer. Just know that the things that cannot be changed are the essence of the deal.... the location and the floor plan are key. Everything else is pretty easy to change eventually, so they will customize it to their liking.
So, in a framed photo at the entry, show a beautiful photo of the pool, and then say that it can be removed if desired upon sale. Just be sure that the deal is done before you tear into anything. I cannot tell you about how many sales are getting knocked apart by bad appraisals now. The bank may say they want some % down, but in reality they may demand more down as the appraisal comes in low. It'd be too sad to tear it apart only to find on the day of closing that something went wrong and the deal is off. So have the check clear the bank before you take it out.
