Is a pool worth the investment for beach property?

[Trent Reeve]

trying to look at just profit numbers. When I vacation near a beach, I know i like to have a pool available too as i dont like the beach every day. Found a house a block or so away at a decent price. Needs some updating, but it also does not have a pool. Want to take my preferences out and make it a business decision. For anyone with knowledge around beach areas, is it worth the cost of putting in a pool?
