In a viral post shared on the U.K.-based discussion website Mumsnet, user Iosca explained that she loaned £4,000 ($4,601) to her friend after she ended up in a “precarious financial situation.”

The Mumsnet user added the friend, from mainland Europe, had been “screwed over” by her landlord.

But the commenter noted that the friend had failed to pay them back and had learned that she knew about her new home.

The Mumsnet user continued: “I’ve lost a lot of respect for her as she has far exceeded the date we agreed that she would pay me back by.

“Anyway, I’m really shocked that she has essentially said she will only be able to afford to pay me back if she moved into my new house (rent is far below market rate.)

“There’s no way I want to live with her due to the way she has conducted herself but I really feel like she is blackmailing me.

“She has s***ged me off to anyone who will listen and shared my every detail of finances - savings, salary, etc to mutual friends.”

The Mumsnet user added: “I drafted a contract, [an] independent witness also signed, but I’m worried it’s meaningless.

“I cannot afford to walk away from the money as I need to set up home with it.”

Since being shared Friday, the post has racked up 290 responses, with many warning the user not to take the supposed friend in.

One Mumsnet user said: “She’s not your friend. Take her to court and cut her off. And never lend anyone money again.”

Another added: “She’s not your friend, whatever you do not let her move in. She will never move out and will take more money from you (likely in unpaid rent.

“She’s already lied about you, stolen your money and s**t stirred. Take her to court to see if you can get your money back but don’t let her in the new place.”

A third commented: “F**k her and her attitude. Letter before action. Take her to small claims. And do not let her into your new home even for a cup of tea. This woman is no friend.”

Newsweek was not able to verify the details of this case. According to property listing website Zumper, rental prices for one-bedroom homes continue to reach new highs.

Unsurprisingly, it found New York is still the priciest city in the U.S., with an average of $3,930 as of August, a 39.9 percent increase year over year.

It added: “Fresno, CA and Tulsa, OK have seen especially fast price hikes: Fresno’s one-bedroom median is up 40 percent year-over-year and Tulsa’s is up 38.9 percent.”
