My area is a 'normal' council estate - a mixture of a all kinds of not-overly-rich people. Several of the houses are now privately owned but most remain under council control. Some of the houses are a credit to their tenants while others are unfit to keep a pig in. However, it's not an area where anyone need be frightened to walk the streets.
I have a friendly relationship with all my clients - even the three that clearly have no intention of ever paying a single penny between now and Doomsday.
However, I also have a good deal of common sense which tells me that handing bundles of money out to strangers who can never ever be compelled to repay a single penny is folly indeed.
There has been mention on this forum of suing bad payers and that suggests to me that the lender must have been in those people's houses and seen goods that a bailiff could seize. Most of my clients have nothing that a bailiff could seize.
There has also been mention of clients paying two or three weeks in advance and/or paying double or treble if the collector doesn't call for a fortnight or so. It astounds me that anyone who could pay in that way would need to borrow money in the first place.
Clearly, something is going wrong and I shall most certainly not be ploughing blindly ahead in the hope that the law of averages will come to my aid. Anyone who thinks I should do so is quite welcome to send me £50,000 which I will lend out as soon as possible and return all repayments and interest on same to the person who sends the money. I won't charge a fee for my services and I'll even pay for my own petrol.
Now, how good does 'going large' sound when it's your money that's at stake? 
But seriously though, folks - I really do need to attract a better class of client!
