If we are talking kennels here, it strikes me that proximity to customers (well, owners, rather than barking, true customers) is extremely useful. Not as far to have to go and drop Rover off for his holiday - all other things being equal.
It further strikes me that kennels in urban areas don't crop up very often, but that is surely because getting planning consent would be a problem - even assuming a business could find a large enough piece of land in a town. Not sure folks would like a barking dog business located next door.
This is not an issue for you - you're there first.
Only issue I could think of - is this going to limit where you can get your handlers to take the pooches for walkies - on urban roads in the future?
