Firstly, this comes about from hours spent on the internet looking at potential properties, then dismissing them (rooms too small, no downstairs toilet, no ensuite, 'garden' really means 'paving slabs with small bush in middle').
Some estate agents don't put up floor plans - how else am I supposed to orientate myself? And those that do have a horrible tendency to make them miniscule (more headache as nose touches screen trying to work out what it says).
Then, we have to consider schools. More double-clicking to view Ofsted reports. Can you rely on something from 2005? How can I tell if the house I am hypothetically interested in is within the catchment area? Our home in London was round the corner from an excellent school but still too far to be considered for a place.
Then there's the on-going headache: wasting my life on the internet looking for the perfect place to live, when I should be re-writing the book (oops!) or playing with the children or doing the washing (yes, everything gets shoved to one side while I dream of my multi-million pound mansion ...!!)
I'm off for a paracetemol and a lie-down.
