Handicap Koi Pond

I was going to buy the house from my sister and her former boyfriend - it had a koi pond in the courtyard.  It was a big house.. long...easy to get lost in.  I hadn't yet seen one whole side of the house...the side that housed Nick's room.  Complete worry sat in as I realized how much they had modified the house to accommodate his handicap.  Worry because I didn't know how they would afford to complete this to any new place they would move.  Woke up feeling as though I had been crying.
