We are working through the process of buying a house built in 1900. At the last minute, it has become apparent that two changes have been made to the property over the years without planning permission, building regulations approval, and in breach of a restrictive covenant, which is in favour of the National Trust.
The first development is the addition of a single storey garage extension (1968) and the second is the conversion of a former integral garage into a living space (1990).
We are being told that the way forward is to buy an indemnity policy (around £500), which would cover expenses in the event that enforcement action was taken by the local authority or the National Trust. However, this would likely not compensate for the loss of value to the house (which might be considerable) if the unauthorised works were reversed. The policy could be transferred with the house for the benefit of future owners.
These policies are usually invalidated by any attempt to inform third parties and so accepting this arrangement would mean we could not seek retrospective planning permission and covenant approval in the future.
All our solicitor will advise is that the risk of enforcement action so many years later is low. However, the risk is not zero and no-one can really say what impact this might have on re-sale. Clearly it is causing us some anxiety and we presume that future buyers would feel the same way.
Although the property was reduced a number of times, we are probably paying very slightly over current market value given how prices are falling in this price bracket locally.
So should we (a) buy and try and make things "right" at our own expense, (b) buy an indemnity policy, (c) make the seller buying an indemnity a condition of sale, (d) ask for a price reduction to share future risk with the seller or (e) run a mile?
