In a recession, currency can lose it's value. In Russia for example, in less than a year the ruble lost more than a third of its value. Same thing can happen anywhere. Much as it might not be as bad here, continuous inflation demands that for one to balance the scales, the rent charged should be adjusted with inflation rates so landlord's aren't the ones to lose out as the value of currency constantly keeps dropping. Question: should the lease agreement take into account inflation so that the rent can gradually be increased as "things" get worse? Or is it better to modify the lease agreement every few months?
