We had three estate agents visit and plumped for the one with the Mont Blanc pen. I will explain...
The first one was who we bought the property from. A pat on the back for our work was welcome, but as it was the only property they had sold in the area and they based their valuation on a nearby town, rather than the slightly rural area, it didn't appear that their experiences would match our hopes for a sale.
The second visitor had used a Rightmove application that allows Estate Agents to see what the market rate in an area should be. He valued it at exactly that market rate. As there appeared no consideration for the fact that everything from the kitchen to the heating to the wiring to the garden was completely brand new, we didn't really think he knew what he was on about. A quick search of other properties on their books suggested much the same.
The guy with the Mont Blanc pen had also sold two houses in our road this year and currently had the most expensive house in the road on his books so we chose him for the job.
