Been in the same Moobaan 3 bed house for the past 10 years from new.
Snag list, incoming wires from meter reversed, septic tank lid not screwed down.
No other real problems, wire to the gate light failed, incoming water pipe joint broke under the kitchen patio, few tiles off in a really bad storm, kitchen sink waste pipe blocked and had to dig it out ...... that's about it, completely happy with the house.
