For house moving related reasons my parents are moving in with my Fiancee and I for about 2 months after Christmas until their new house is ready (new build). We are happy to do this for them and offered, they did not ask. They did look at short term lets but shortest time is 6 months and would hate to see them waste all that money. We have enough room and all get on well and parents have already said they will contribute financially for day to day expenses etc.
However as lovely as my parents are living with them will come with its challenges (as I'm sure they think about living with us!); has anyone got any tips on how to not kill each other!?
