A loud spat erupted yesterday on Twitter between TV housing pundit Henry Pryor and Vanessa Warwick of landlord website Property Tribes.

It was over the campaign against the so-called ‘tenant tax’ – in reality, the phased-in changes to the tax treatment of mortgaged landlords which begins tomorrow, and which was introduced under Section 24 of the Finance Act following George Osborne’s Budget of last year.

Pryor opened fire with: “Lots of respectable people are going to tell you that there’s a ‘Tenant Tax’ coming in on Thursday. There isn’t.”

He went on to demand: “Is Section 24 about the tax treatment of a minority of landlords? How many tenants will be taxed more?”

Not letting the matter drop, he went on: “This is complete nonsense and may unsettle a lot of tenants quite unnecessarily. It is not a tenant tax & most landlords aren’t affected.”

Warwick protested: “Why are you attacking me Henry? I am just sharing information.”

She told him that he was a member of Property Tribes, “so feel free to post your thoughts there”. She said she would not respond to him further.

Pryor appeared to have the last word, saying he had deleted his account and telling Warwick: “If you can’t debate & you can’t be clear about what you support & what you report then it has little value.”

However, he then went on to lock horns with others, describing a claim from the Residential Landlords Association that 1m families would see their rents go up as scaremongering and “complete pants”.

Engaging with Steve Bolton, founder of the ‘Tenant Tax’ campaign, Pryor next said: “I gather that as a tenant, I’m facing a new tax from Thursday. Can you tell me more please.”

A calm Bolton replied that he got Pryor’s point. Landlords would have to pay more tax, but the evidence showed tenants would suffer higher rents.

A mollified Pryor congratulated Bolton on his “measured, polite and adult” response. Pryor even wished him good luck with his campaign.

We don’t, however, think this will be the end of it . . .
