The move to new premises or indeed a retirement situation can be troublesome.
Delays are common so the need to be regularly updated by a builder or retirement facility management is vital because there is a need to sell and settle the sale of existing premises.
The settlement must coincide with the move in date otherwise you could be without a home and that could mean temporary accommodation and the need to store furniture. Disruptive to life and costly!
When talking to your lawyer regarding the contract of sale make sure you allow a suitable time to accommodate delays and then instruct the selling agent accordingly. We have seen delays of up to 6 months so there is a real need for careful planning.
