Jillian (48) made a video of her plush Wicklow home, which was once valued at €1.6m, in an attempt to attract buyers.
And even though she received an offer of €500,000 over two years ago, the mortgage lender refused to accept it.
The divorced mother-of-two is in massive negative equity and hasn't been able to live in her home for several years.
She bought Raheengraney House for more than €1m and the bank has continued to look for €900,000 in mortgage repayments.
"Two years ago the bank refused to take a cash offer of €500,000, because it didn't equal the mortgage," she told the Herald.
"Towards the end of last year I stopped paying the mortgage. I couldn't afford it any more. I have since received notice of repossession orders.
"I have tried to drop the house price again and have had 50 different people looking at it," she added.
"We recently received an offer of €205,000, but it wasn't enough."
Jillian said that it breaks her heart to know that she is so close to losing everything she tried to build up.
"The thing is, I had a lovely home in Dublin but I sold it to run a guesthouse (in Wicklow)," she said.
"People say to me that I should be glad to get rid of it (Raheengraney House), but I lost my home at the same time."
"I am now 48 years old with two children and no security," she said. "If I am sick in the morning, I don't have a house to fall back on."
Jillian said she has explored all avenues, from making a video of the house on YouTube to crowdsourcing in an attempt to create a wedding venue.
She has now written a book about her experiences, Does My Debt Look Big In This? It's available to buy at www.lulu.com.
