Q.Willow Tree Worries Re House
I’m in the process of purchasing a house which has a weeping willow in the garden. I’m not sure of its exact type but estimate it to be about 5 meters tall and situated about 15 meters from the nearest point of the house. I’m worried it could affect the foundations in the future. Would you recommend having it removed or would getting it cut back Regularly be sufficient?

From everything I've read, they should not be planted in a residential yard. The roots will not only affect the foundation, but any underground pipes or other structures on your property. I would advise removing it and replacing it with a tree suitable for residential landscapes.
