HI. We are out on Whidbey so close to you. TFP has been great help as per mknauss.
Couple other comments.
We bought house with pool. But as sale approached previous owner lost interest in maintaining the pool and when we occupied, it was green. Had to start from scratch.
So...
Insofar as possible, in whatever way you can, try to keep it in shape between now and May 1.
Second
Previous owner left us no directions, no habits, no equipment.
So...
Insofar as possible, get their directions, habits, personal equipment and leftover chemicals.
And last
Previous owner left us no records, where this was bought, when that was bought, etc. Which made things tough.
So...
Insofar as possible, get their repair, replace records.
