If you've got time, get an inspection of the pool, by someone equipped to evaluate its condition. Rehabs for inground pool can easily run into the multi-thousands, and some very expensive repairs can be overlooked by someone who's not knowledgeable.

Or, you might want to negotiate a conditional price reduction, based on what repairs are needed to get the pool in adequate condition to operate for, say, two pool seasons.

But, unless you've got a fat wallet, and really enjoy pools, I wouldn't buy the house without a clear understanding of what the pool is likely to need.
