If son has lived independently until bloody Covid came along then he should be able to sort himself out in the coming months & his financial difficulties may only be temporary , even being able to eventually pay back any monies given to him by mum. Daughter is still dependent on living at home. It costs a lot to live independently & if her income is low may not be able to afford to move out but ought to be contributing to the household expenses.
I agree that if OP wants to retire, or reduce work commitments, then giving a 3-6 month warning gives ACs time to sort their finances out. That seems reasonable and fair to all concerned.
