If it affords at any time much less than this, other trades will soon draw so much capital from it as will again raise that profit.
Whatever part of the whole rent of a house is over and above what is sufficient for affording this reasonable profit, naturally goes to the ground-rent; and, where the owner of the ground and the owner of the building are two different persons, is, in most cases, completely paid to the former. This surplus rent is the price which the inhabitant of the house pays for some real or supposed advantage of the situation. In country houses, at a distance from any great town, where there is plenty of ground to chuse upon, the ground-rent is scarce anything, or no more than what the ground which the house stands upon would pay, if employed in agriculture. In country villas, in the neighbourhood of some great town, it is sometimes a good deal higher; and the peculiar conveniency or beauty of situation is there frequently very well paid for. Ground-rents are generally highest in the capital, and in those particular parts of it where there happens to be the greatest demand for houses, whatever be the reason of that demand, whether for trade and business, for pleasure and society, or for mere vanity and fashion.
