There is a new listing on Magnolia Av near downtown that has a pool. One reason you do not see that many pools is that the lot sizes in the Fruit & Nut District are small. Do keep in mind that you can join Lakewwod Country Club and use their pool as well as, the pool and beach at the Grand Hotel.
Why not buy a house with land & just put one in? There's a nice big house listed at 14073 State Highway 181, sitting on 10 acres with a barn in back giving plenty of land to put in a pool! The house is brick - all one level with 4+ bedrooms 3 & 1 half baths with lots & lots of extras. The master suite is to dye for & has a walk in closet the size of a nursery! The house price is unusually low for the value! That home would be twice as much money anywhere else in the US!
There are fewer homes with pools and likewise fewer buyers for homes with pools than without. I think what you are experiencing is this year we have had fewer homes come onto the market and it has been challenging to find properties for some buyers. Inventory for some, such as yourself, is low. It may be a good idea to set-up an auto-search for homes with pools, that way if one pops up, you will know right away. Let me know if I can help.
I can help you with that. I have search capabilities via the MLS system that the general public doesn't have. If you aren't already working with an agent to do this for you, give me a call and I'll be glad to get all the information I need to find you options. We have one listing on Danne Road that has a pool and which is shown under my Trulia listings.
