House buyers family and friends

When we were buying this house, i arranged a visit to measure up via the estate agent, who accompanied me to the property, but the owner said he needn’t to stay. She actually helped me with the measuring and we had a friendly chat.
There is no way potential buyers should be given a key before completion.
In a previous property we were selling, we had moved out into temporary rented property in a new area. Our former neighbours rang us to let us know that our buyers had been given a key and had actually started decorating! Totally out of order. We gave the agents a rocket, and our solicitor ordered the buyers to keep out until completion. At least that house was empty, but yours is full of your possessions, Vintagejazz.

I would have been absolutely furious and asked everyone to leave.
Taking over your home with family members when it was a strictly time allotted appointment for measuring only is a definite no no.
The agent should have been there, a very strong letter I think is in order to the agent with consideration of reducing the agents fee.
Unbelievable.

I really did not think this happened any more. About 35 years ago, the house next door was up for sale and the estate agents released keys out to viewers. The keys got copied and the house was emptied by people posing as a removal company.
I am amazed that estate agents release keys still.
