Hard to say Fred without knowing your market and price range and how the house compares to otehrs...Here this is pretty unusual....and we have listed a couple. The people who bought them in both cases had Physical therapy needs....and welcomed the opportunity to exercise in their own homes.....that may be a shot for you 

/swim party for the neighborhood and ask them to bring friends that may be interested in purchasing.

You could put a couple of drop dead girls in the pool .

I would guess that it is time for a price reduction.

Indoor pools can be very nice but many home buyers do not want to face the expense and the dampness that can be caused.

Maybe it's not the marketing that's the issue. It might be the price and/or location. Don't throw away money on marketing if that's the case. I had a one of a kind, gorgeous multimillion dollar home that was in a beautiful neighborhood but didn't warrant the price. The listing expired and 3 years later is still on the market with another Realtor.

Fred... I'd be happy to provide ideas but I don't have any idea what you've done to-date to market and/or if the asking price is in line with market values.

Fred Hafdelin there are three things that will help your listing sell.

Price, Price, Price

You might want to post 4 pics of the indoor pool with noticeable 'changes in season' and the same people bouncing a beach ball around. :D
(Same pic of the pool, change the scenery outside a window if you can do that.)

 One thing that does work in our marketplace is Facebook ads.  You can pick what likes the person has to narrow down the specific such as people who like certain types of pages. This may assist in targeting a market tailored to your home.  It shows results. The person is a former agent those numbers may be the back up you need , showing that the interest is there but the price has to be adjusted.  

Fred, it seems that you have a lot of input here from some very smart people.  I just don't have enough data to be of much help.

Fred,

It would be difficult to give you an idea, without knowing a thing about your area.  My guess is price, and that in your market people don't really want an indoor pool.  Wishing you all the best.  A

Your question got my attention no problem. The idea of floating around inside your home while eating, watching a movie or conversing is a privilege & luxury to be sure. Indoor pool? I would prefer this that an outdoor any day

Price!

everything sells at the right price..... 

The right price is likely the best marketing decision you can make since you identified that as an issue along with the pool itself in your reply to the answer by Ronald Gombach.  You know what needs to be done -- it doesn't seem the owners are on board.   That's a serious disconnect.

I've only been able to find Buyers for 2 properties with indoor pools.  One had to be drained and a new floor built over the top of it!!  It became a lovely family room

Several others languished on the market and still have not sold 5 & 6 years later and through many other brokerages.  They're a tough sell even when priced correctly.   Good luck!

Fred Hafdelin There are some good ideas here. Good luck with the sale.

Overpriced won't help you, but you could market it as "Here is a home with a pool that you can swim in.. year-round"!

 Indoor pool in Mountain Lake NJ.

One option is the customary price beat down on the owner. You already admit the property is overpriced. Then suggest the 'ex-Realtor' owner is overconfident regarding the value. I NEVER advocate a price beatdown. Such 'one dimensional' marketing is not appealing to me.

#1. Demonstrate through actually numbers that your marketing is working. (L1 + L2>montly sales)

#2. Consider paying for a CC type trailer that you can leverage long after the property is sold or out of your listing inventory. You will need to hire talent to make this worthwhile.

#3. Press the owner for their REAL goal in selling this real estate. That will be a 5, 6 or 7 answer.

#4. Conform the marketing to the real goal.

The truth may be you are simply renting the front yard (no true motivation to sell), so make the most of it.

PS: When talking about specific real estate, one should include a link. That is good marketing.

I would say it depends on how long the property has been listed, how is it priced, any offers and what is the feed back. 

If its overpriced and has been since day one, it has lost its luster to the market. That will be very hard to challenge.

The only one suggestion that I have since maintenance has been commented on, is to have your seller give you a one-year breakdown of costs. I would add that to your agent documents on the MLS, and also add to your marketing book. That way you can either confirm or debate the perception of what it costs to have an indoor pool. They are much less than outdoor pools if I remember correctly.

If the seller refuses to reduce to what the "market" says is the price, you may have to review the value of your time....

Best of luck on this one! 

 Having same issue w/ a very unique property w/ an indoor pool. I did a BLOG on the benefits of an indoor pool.

Homes with pools seem to always take longer to sell in this area. Many people don't want to deal with the expense of maintenance, are are worried about liability. If pool doesn't add a lot of value to property, I would get rid of it, or convert it into some other use. Vault, wine cellar, fall out shelter, storage, etc, etc.

Most likely price is the barrier due to perceived ongoing maintenance costs.  Perhaps it would help if you got a handle on this.  Maybe the actual costs are lower than what buyers are thinking.

Sounds like a nice home, hope you found a buyer for it.

Price will always sell a home.    I have never had a buyer that would want an indoor pool.   Good luck!

It may be the price.

Fred,
I’m being serious, not snarky, if you and I worked together I would ask if this is a listing where you need to cut your losses and spend your time and energy on something that will sell. 

First off yo need to find out what is the main issue.

In my area, the pool is a negative

Without seeing the property, it can be hard to come up with ideas.  Reading through the other responses price seems to be the biggest recommendation.  Shana has an intersting idea about a pool party, but I'd be worried about liability and getting a lifeguard.

Sorry, Fred.  I have no clue.

Of course hope you have a sign outside with has inside pool

With water being liquid gold in our area pools are not desired by most and we have few of them.  Wish I could help with this one.

I would determine who the most probable buyer is and target my marketing to them. You have to know where buyers are most likely coming from to know where to market as well. If the pool is a barrier for some, market to those who would love the pool. It sounds like a dream home. Pictures sell.

I would say most likely price is the barrier due to perceived ongoing maintenance costs. I had a home listed with an indoor pool and it came down to price. Outdoor pools here are very popular and will most always be a plus not indoor pools. Sally K. & David L. Hanson had the best take for a fresh approach at a target group.
