Through the years I've owned homes both with and without a fireplace. Given the choice I would rather have one. They appeal to others even if they don't to you. So if and when you sell it, it very well could help, by giving the home added appeal to potential buyers.
Besides, if you don't want one, and end up buying a house with one, just keep the flue closed and don't use it. Nothing lost, but again, it might help with a future sale.
It's not like a swimming pool, that you have to maintain by constantly cleaning and adding chemicals, regardless if you use it or not. I grew tired of our pool in the last house we had. It became too much work and expense for the amount we used it....... Which was almost never.
But our realtor told us the people who bought it absolutely loved the pool. And for them it was a deal maker. So in that regard, it was worth it. Pools are like boats. The 2 greatest days are the day you buy it, and the day you sell it.
