Hi Seller 03,
I doubt there is actual real data for you..... but I can provide you with a few thoughts based on experiences with buyers....
Large luxury homes and estates with a lovely view and a beautiful indoor or outdoor pool are not a problem, then it just becomes the personal preference of the next buyer....
When looking at an average home..... maintenance, cost of maintenance, insurance and liability and often
couples with young children tend to prefer not to have a pool, not all of them but many..... So in general terms
all my buyers in the past looking in the Northshore, unless they were looking for a luxury estate or luxury home, preferred not to have a pool.... There is really no way to give you some statistically correct response.
In other words, only for a few buyers would a pool be an advantage they are ready to put in the extra efforts, expenses and care.
If I come across some additional data and information I will get back to you and pass it on.
If you need any further questions answered or would like to have a look at some properties in the NBK and surrounding suburbs that had outdoor pools let us know and we would love to provide you with that addtional information.
