Having had a garden during lockdown was a factor in the choice to stay for more than half (53%), while 26% simply realised how much they love their home.
OneFamily also found that 23% of over-50s were keen on keeping space at home for loved ones to visit, while 21% wanted to remain in their current house in order to pass it on to family.
On the financial side, factors such as high house prices (10%), as well as the hassle and cost of moving (31%) were major influences.
Three in five (60%) over-50s said they are unlikely to move house any time soon.
Of these, 24% would consider taking out equity release to free up cash from the value of their property.
Meanwhile, 17% say they would rather spend money to make their house more accessible than relocate.
The same proportion (17%) say they would be very reluctant to move to a smaller warden-assisted flat or care home in old age.
While one in 20 (5%) over-50s had already taken out equity release, OneFamily said this appetite for renovation rather than relocation could drive new uptake.
Paul Bridgwater, head of products at OneFamily, said: “One side effect of the pandemic is that homeowners have grown more attached to where they are living.
“Whether that’s down to having appreciated access to green space, or more intangible factors like family ties and memories attached to a home, our research suggests people seem to be more reluctant to look into downsizing or relocating than they were before.
“But staying in a forever home can mean extra expenses.
“As such, we may be set to see a rise in equity release uptake to fund renovations and adjustments to improve or adapt homes to allow for the more complex needs of later life.
“Taking out equity release is a decision to be weighed up carefully with input from family members.
“It won’t be the right solution for everyone but if this trend for staying in the family home continues to grow, advisers will play a key role in helping over-50s explore their options and make the right choices.”
