We moved out while we were doing our work. The schedule was 4 months, and we arranged to rent for 6.
We were ahead of schedule until it was time to lay the wood floor. The (well known flooring company) didn't order our floor, despite us paying well in advance, and so when it was time for delivery, they could only provide some. I think they wanted to fob us off with a different, similar floor, and that if they left it, we would be so desperate, we would agree.
Once the floor was laid, it was found to be faulty. I think the manufacture had been rushed.
So, in the end, they provided a much more expensive floor for the same money (not what I had chosen, though). We were also given some compensation, but it didn't even cover our additional costs, let alone anything for "distress".
All his added an extra 4 months to the schedule, and we had to extend our rental for another two months. Luckily, the LL agreed to do it on a rolling agreement, rather than us having to sign up for a second six months.
So, my advice is, have a contingency fund!
