An estimated 480 homes across Cavan and Monaghan remain in mortgage arrears of 12 months or more, with many tracing their difficulties back to the period between 2008 and 2010.
More than 15 years after the financial crash, thousands of households across Ireland are still living with its consequences.
In Cavan, an estimated 270 homes are in mortgage arrears of 12 months or more and in Monaghan, an estimated 210 homes are in mortgage arrears of 12 months or more.
Meanwhile, 160 Cavan mortgage accounts and 130 Monaghan mortgage accounts have been threatened with legal action or are already within the legal system.
Stephen Curtis is the CEO of Irish Homes.
Speaking on today's Joe Finnegan Show, he said these figures underline the number of families facing prolonged uncertainty about their homes.
He believes the figures also point to a cohort of borrowers who have been living under intense financial pressure for years, many of whom are now approaching retirement age.
The Mortgage to Rent scheme (MTR) is a government led initiative to assist eligible borrowers who are in long-term mortgage arrears and at risk of losing their homes.
Mr Curtis outlined how this scheme can help those in arrears: "Under the scheme, the property is purchased by an approved housing body or an approved private provider, the borrower's unsustainable mortgage debt is cleared or written off, and the family remains living in the home as a social housing tenant, paying rent that is linked to their income rather than the original mortgage.
"Remedial works and energy upgrades are typically carried out as part of the process, to bring the property up to lettable standards. While ownership changes, the household gains long-term housing security through a formal tenancy, with the possibility of buying back the home in the future if their financial situation improves.
"For households whose mortgage is no longer sustainable, Mortgage to Rent can provide housing security and stability when there are few if indeed no other potential solutions. Households in long-term mortgage arrears, or those facing legal action on their family home, are encouraged to seek advice and explore all available supports at an early stage."
