in cornwall have min of £6, but a lot of my houses are 2 doors and 5 windows starter homes, as that is all they seem to build down here, there is a awful lot of bungys down here but i avoid them as in 18 months of knocking havent picked up one yet, either get told no or we have one, can go knock a council estate and pick up 20 in a day and end up keeping about 18, i tend to lose more on private estates than council estates
