Dp and i both own property, both mortgaged but we live in mine. We've kept his as its handy given where it is but it will never be rented out. We're now talking about getting married but im unsure of the reprocussions in terms of effectively having a second property. What happens if we want to sell up and move? What happens if we sell his and buy a holiday home (again it would only be used by us)? Is there anything we need to consider?
