This hapopened to a friend of mine. her mum sold her house and moved in with her parents and so gave all her children 100K until she was ready to buy again.

My GF put the money onto her mortage and then just re drew when it was time to give it back to her mum. I believe it made a huge difference even though it was only for a bit over a year, it was hard seeing theinterest going back up afterwards.

All in all it was better than her mum being taxed and her mortage interest being high over that period.

Hope that makes sense?
