A BBC Inside Out programme this evening will highlight buy-to-let pitfalls.

The show will feature a landlord whose portfolio of housing benefit tenants is causing him to scale back his investments following the need to instruct evictions firm Landlord Action to handle two of the cases shown in the programme.

Brian Nixon, a builder from south-east London, has a portfolio of properties largely rented to tenants receiving housing benefit.

One of his tenants is in £6,000 arrears because she failed to fill out the necessary housing benefit forms, but never informed the landlord.

Despite numerous warnings of eviction, the bailiff – who had 14 other cases that day – is shown as having to wait around while the tenant collected what belongings she requires, leaving the rest to be dealt with by the landlord.

In addition to the rent arrears, viewers will be left shocked at the state of the property on departure of the tenant who, after being evicted, went straight to the council to be rehoused. The aggrieved landlord uses some colourful language to vent his frustration.

Paul Shamplina, founder of Landlord Action, who is present at the evictions and can be seen on tonight’s programme, said: “I have said it many times before, a system where landlords do not receive housing benefit directly from the council is simply not working.

“Years ago, renting to social housing tenants gave landlords a steady guaranteed flow of income, in return for supporting this sector by propping up the limited accommodation the council could offer. Everyone benefited.

“Now, we are seeing fewer landlords wanting to rent to housing benefit tenants because of cuts being made, the uncertainty with regards to Universal Credit and non-direct payment, particularly in the south-east where landlords could achieve far higher rent if they let to the private sector.”

He said Brian Nixon is now selling properties from his portfolio, meaning there are three fewer properties in the private rented sector being used for housing benefit tenants.

* Inside Out can be seen this evening at 7.30pm on BBC1 London, Sky channel 954 or Freeview channel 721.
