Unfortunately my daughter has separated from her partner with a 2 year old. She saved to buy the house they both lived in and both paid half the mortgage after they got together. He is not making any claim on the house as it was a short lived relationship which is fortunate in the circumstances. He has however said he wants not part in my granddaughter’s life which has left my daughter deciding to go part time to four days a week which will obviously reduce her income drastically. I know she will be able to claim maintenance but we don’t know what that looks like and I wouldn’t like her to rely on that. Me and DH both think she now needs to move to find somewhere with lesser mortgage payments, daughter is saying 1,100 for a four bed house is a good deal and it would be pointless moving now. She’s never told us her finances before but I am shocked she is now left paying this, surely this is far too much to pay especially as a single parent? Am I unreasonable to encourage her to downsize and get somewhere which much lesser payments? Her current rate is fixed until 2027 but it is portable. I am very worried for her.
