My wife and i are are likely going to submit an offer on a foreclosed home. The house itself is actually in pretty good condition. The backyard, however, has a lovely swamp that is supposedly a "pool." In all seriousness, the pool is a 20x40 inground liner pool. The pictures below show it's current condition. What would be my best course of action? You cant see through the scum but given the large growth hardwoods and southern pines surrounding the pool, i can only guess at the amount of leaf matter in the pool. The house has been foreclosed since March but my guess is the pool has been abandoned longer than that. The large suction pump does work, the small pump (what is this for?) just hums. I grew up with a liner pool so i have a grasp on general maintenance - but this is an extreme case.
