As far as added value, there will not be much. I think you get something like .20 cents on the dollar. Pools can run from 30,000 to 100,000+. But adding a pool to your home will increase the chance that your kids (if you have them) will stay at home and invite their friends over for a day in the sun. Plus when you have parties you have the option of being pool side. I personally love pools and love the luxury of getting up in the morning and jumping in to wake up. I agree with Kevin P. you many run into a problem selling your home if buyers are not looking for swimming pools. But at the same time you might get lost of buyers who are looking for a pool and buy yours. Donâ€™t second guess yourself on this one. If you can buy a pool and you will use it then I say put one in. Also keep in mind that your electric bill will increase and over all up keep of the pool will run around 70-100 dollars per month.
There are some improvements that are simply for your enjoyment. Both pools and hot tubs are in that category. If you believe that you will enjoy it much of the year and recoup the cost of maintenance and installation in enjoyment and conveniance a pool might be for you.
Occasionally we will run across someone that just has to have a pool and they can be great buyers for your home. However, even they will look at it as a savings to them compared to installing a pool themselves.
You may be better off selling your current home and buying a home with a pool to ensure that you won't be the one to take the monetary hit.
Having said all of this, if you're going to be living in the home for a number of years, I would say go ahead and put in a pool if it's something you would enjoy having. _Don't_ put it in, however, as an "investment." If you have, say, $50K sitting around burning a hole in your pocket, and you're thinking of putting it into your home in a positive-ROI project, better spend that money on a swank kitchen or bathroom upgrade.
In parts of the $2M+ market, especially at, say, $4M and above, a pool is pretty much expected.
I wouldn't suggest trying to squeeze a pool right next to the house....which many people do either due to lack of yard or because it "appears" more cosmetically convenient. (Termites love moisture too!) A distance of 25-30 feet away from the facing door/outer wall of the home is a good distance to place a pool for concrete slab homes.
Safety is another reason for not having a pool squeezing up against a home. Reaction time is just as important to a crowd of inebriated individuals as it is to parents of small children. Plus, it is overall more convenient and less cost to fence comfortably around a pool area than it is a whole yard.....unless, of course, the pool is the sum of the yard. ;)
The view is another reason for having a swimming pool in Texas. If you are lucky enough to have open land, the sky scenery is beautiful 24/7 and the Milky Way along with a tapestry of stars truly do come out at night, espcially when drifting and relaxing on an air mattress and listening to your favorite music or just quietly enjoying the majesties of life.
So, to answer your question: The value is what you make of it, not what others superficially assume to categorize.
A pool that is well both pleasing to the eye (design, tile color, solar paneled, etc) and landscaped into the yard vs. being the focus of the yard could add value at the time of sale.
A pool can be a bit tricky. As a deck, built in BBQ, or any other improvement for enjoyment.
If you plan on being in your home for 7+ years and will have a pool of high quaity and landscaping implemented, then yes, put in your pool. The enjoyment factor is important as a homowner and you should not be overly concerned about resale - at least not with this type of improvement. When you are ready to sell, you will find a buyer who appreciates a pool as much as you.
It's an interesting question. I would ask you how important is the pool to you and your family? And, are you willing to invest in building a pool for your own pleasure?
In my experience, clients will either want a pool or will specifically look for properties WITHOUT a pool. A nice pool in and around Pasadena, CA will run you about $45,000 to $50,000. Will you recoup the investment - most likely not. Will it add a bit of value to your property - maybe.
Remember, not everyone wants the pool and the maintenance costs/responsibilities that come along with it.
Install a pool if it will make you and your family happy.
