Depending on you plan for future use of the pool location and local codes, it may be most cost effective to perform a burial as opposed to a removal....just saying?
As mentioned in a previous answer below, there are a number of factors that will determine the cost. The contractor will also need to assess how accessible the machinery is to the job site.
We dealt with this a few years ago on a listing and the cost was under $10,000 based on all the factors involved. It would be wise to check with the Government Center on permit requirements. This is not a difficult process and the contractor you hire can also take care of this.
Good luck with the house and hope this helps with the decision unless you bought the house by now!
Many homes are valued higher with pool now in residential market families have limited budgets for travel seeking backyard as an escape with entertainment
There also may be some zoning laws that are of concern. Check with your local zoning board.
Consult with a general contractor in your area to get a better idea.
