A sleazy landlord in Wales was caught on hidden camera offering a woman rent for free in return for sexual favours.

'Rent for sex' is a new phenomenon that is sweeping areas such as Wales where landlords will offer reduced or free rent in return for another form of payment.

These lone landlords will list their properties on Craigslist and advertise them under the guise that they are 'rent free' for an 'alternative payment'.

This trend comes as 250,000 women in the UK say they have been offered free rent in exchange for sexual favours in the past five years.

And 190,000 female tenants say they have been propositioned by prospective landlords in the last year, according to a YouGov poll.

One man was caught on hidden camera offering an undercover reporter free rent if she had sex with him once a week. The interaction was aired on S4C, ITV Wales' programme Ein Byd.

A landlord in Cardiff told an undercover reporter from ITV Wales' programme Ein Byd that she could have accommodations for free if she had sex with him once a week

He advertised is property in Cardiff on Craigslist for £650 per month, but he said 'a reduced deposit/rent' was available for 'alternative payments'.

The landlord met undercover investigator Siân Thomas who was posing as a female interested in the arrangement.

She caught on hidden camera how he thought the arrangement would work if she chose to move into his property.

During the meeting, he offered a one-bedroom annex for the payment of sex once a week.

In the video the landlord said: 'I don't want to suggest anything that makes you run a mile but I want to help you out.

'I don't know if you have heard of a sort of a friends with benefits sort of arrangement.'

The property was listed on Craigslist for £650 per month but the description stated a female could have it for a 'reduced deposit/rent for alternative payments'

The news organisation contacted the landlord after the meeting asking for his comment on the arrangement. He apologized and begged them not to air the documentary

It is not illegal for someone to post an advert on websites such as Craigslist about these type of arrangements. But it is illegal for someone to enforce the arrangement under the Sexual Offenses Act 2003.

The law states it is a crime when a person causes someone else to become a prostitute.

Ein Byd reporter Siôn Jenkins contacted the landlord after the meeting to ask him for his comment on the arrangement.

The landlord responded in an email begging the news organisation to not publish the footage and 'expose him as a monster'.

He said: 'I should have trusted my gut and not done this. I'm such a fool, but this will ruin everything I have left everywhere.'
