Them coasters are invading every thread!!
Meldy, I haven't read the thread, but squeeze the vendors balls. I don't care what you hear on the news, it's still a buyers market. Pick 3 or 4 properties, and don't get attached to them until your offer has been accepted. Saving £5K now could save you nearer £15K at the end of your mortgage. For instance, if the property is going for £150K, I wouldn't come in higher than £130K. They will always come back to you.
Some people are up to their neck in debt, they have to sell, full stop.
Find out how long the property has been up for sale. Check with the land registry, for how much the property on that street has recently sold for.
