Zoopla’s research shows 47% of people who are still sharing a mortgage with an ex pinpoint the cost of moving out as their main reason for staying. As well as the fees associated with selling and buying a home or breaking a rental agreement, there’s also the difficulty of affording to live alone. Data shows single people carry a more significant financial burden and spend more per year on basic expenses than their coupled-up counterparts (in the US, this is particularly exacerbated by health-care costs). And the past 10 years have seen a significant rise in people turning to house-shares due to the unaffordability of renting by themselves.
