Mountain said legal back-and-forths went on for most of 2026 before bailiffs went in and she got the keys back at the start of September.
She claimed she was £20,000 down because of what happened.
“It has caused so much stress,” she said.
“I feel like I have missed a lot of my children’s childhood and enjoying my motherhood because it’s been really horrible to have to deal with all of this.”
Chris Norris, from the National Residential Landlords Association, told the BBC the “vast majority of tenancies run to everyone’s satisfaction and there are not major disputes”.
But he added, when things go wrong, landlords are at the mercy of the courts.
“There can be very, very long waits… and that’s where landlords tend to find themselves out of pocket.
“There’s also likely to be some trashing of the property when you’ve had those kind of disputes,” he said.
But renters have previously told the BBC about significant difficulties they have faced too, including paying “70% of their salaries” in rent, and having to move multiple times.
