Tenancy agreement bullying

We have found that signing a tenancy agreement leaves you at the short end of the stick, but, no signature means no tenancy. By law, you should be allowed to continue on a month to month basis, once you have outrun the initial six or twelve months contract. Legal practice, however, is that owners, via rental agents, make you sign one six months contract after the other. But what can you do? If you do not sign, you must vacate. So, you are forced to move at a specific time which suits only the landlord. This is why I keep saying, The law is used to protect the abuser, not the abused. Also, legally a bond has to be passed on from rental property to another and topped up or reduced as required, however, legal practice is that you have to pay the new bond in full before you have received back the previous bond. Once again, favouring the landlord and leaving the tenant vulnerable. All this, while there are so many restrictions put on the tenant as to how many people and what you are allowed to do in the house. Plus disruptive renovations are happening while the tenant pays the same top dollar for a place of peace. This sort of law, forcing people who live real lives to live in sentences on a piece of paper, has to be stopped.
