There is over 200 miles between these 2 destinations so a house in the middle would mean a long commute everyday. Even without heavy traffic your are probably looking at at least 2 hours each way for both of you so 4 hours travelling time each per day! I would suggest, if you can, have a property at each destination. Maybe a house in Lytham and a small flat in london and get your husband to come home at weekends.
