The overall layout hadn't changed, but the fixings like the wires, pipes and switches were all new, and were waterproof and rustproof.
There wouldn't be another incident like Luke helping Max repair the bathroom pipe in the middle of the night.
The doors and windows that couldn't be opened were replaced with new ones.
More importantly, the rent hadn't changed.
That meant that the landlord was proactively covering the repair costs, which was his legal responsibility, anyway. However, it didn't make sense.
The original landlord had entrusted a professional real estate company to collect the rent, and there was no need to inform Max and the others about the change in landlord.
As long as the landlord and the tenants had no objections to the repairs, they could just let the real estate company know.
