The Grass

Well... Steph and I are three days away from the closing day for our house. We've managed to get all our finances together (... surprisingly, with a little kaching left to spare in our bank account!). Now we're just worried about the condition that the former owners will leave it in.
We do get to do a final walk-through before we close (in case we need to hold back any kaching for repairs or disposal of trash on closing) but who really wants to go through all that?
We're hoping to be able to just walk in, do a little cleaning and settle.
But Steph did a 'drive-by' earlier this week and it seems that they haven't cut the grass. Possibly for weeks. Maybe months. Oy.
Is it fairly normal for people to leave a mess behind? Or is anyone still considerate enough to clean up before they leave?
We'll find out! ... on Monday
