Fourth time tenants have been asked to mow the lawn, once they said on the inspection day it would be mowed that weekend, next agent phoned, next agent wrote letter, now I have just rung the fourth time to complain (as the lady owner in the townhouse behind is complaining which I dont blame her, it looks very scruffy) Can I give them two months notice over this? They are on lease, but could I suggest we hire a gardener and increase the rent mid lease? Could anyone advise what my options are?
