I moved from Hampshire to jersey, when my first baby was barely 10 weeks old. We had a bank house as we were nit allowed to buy.
The previous tenants, also bank employees, knew the situation as DH had asked to delay starting work for a week as our baby was due then! He left for jersey and came home weekends, sea fog permitting.
The previous tenants not only left everything filthy but also removed every solitary lightbulb. I sat down on the floor and cried.
After that experience, I not only cleaned the house, but also left loo paper, information about rubbish collection, doctors, plumbers, etc.
it was never reciprocated. Most houses I moved into after were never especially clean, but useable.
