This extraordinary generosity stands in stark contrast to exploitation of the countless charlatans and tricksters who will quite happily charge hundreds of pounds just to tell me what my property might be worth.
I tell these chancers in no uncertain terms that I won't tolerate their exorbitant valuation fees, when other kindly agents are issuing invitations for FREE.
You have to be careful with estate agents these days though. In the December edition of a glossy mag called South West, which I picked up on a train, there's a profile of a couple of guys from a posh London firm. One of them has been drafted in from the military.
Talking about the dangers of being on the front line of the property war in Barnes, he says: 'In the Marines, we used to have a saying: improvise, adapt and overcome. I think that fits in quite well with the conditions of our job.'
That's the spirit, my old son. If you see any incoming mansion tax or a Eurozone crisis on the horizon, keep a steady nerve. Improvise, adapt, overcome.
Perhaps even consider invitations to free valuations. There's no better way of out-gunning your rivals.
