We accepted an offer on our house in December. Our house is 10 years old. The potential buyers made two visit before offering. Both long visits just under 2 hours long. The second visit they brought along their surveyor friend to check out the house with them. They then came for a third visit after their offer was accepted with a list of items they wanted to check. This time I asked them to stick to an hour, they came with a list of items to check and literally ran around the house ticking off items on their list. They have had a very detailed survey done by the same surveyor friend who spent 6 hours on it. Fair enough they want to be thorough.
They now want to come again for 2 hours with a builder. The agent has implied a further visit might also be needed to check which fixtures they want to keep. There aren’t really many, just a few blinds.
Is this normal? Am I allowed at any point to say enough is enough? I haven’t sold a property before, genuinely interested on if this is just the norm.
