tenants who exploit, misuse, harass, misbehave and yet shamelessly want landlords to help

A tenant pays rent of Rs. 40/- p.m. . Misuse common passages etc for storing his belongings. In the mid  night he makes noise by throwing steel vessels ( for what he knows). He has kept surroundings very badly. There was a time when he would go up on terrace and piss in open. He does money lending business by keeping valuables of poor street hawkers etc who keep barging in on common passages on first floor residential areas affecting our safety.

Our mistake : My father gave him his own room without charging anything extra as he belonged to our own community from our hometown and was relative of a close well wisher.

I just got up and came out of my room this morning and Lo! he catches hold of me. He tells that the ceiling plaster has fallen and I must see that. He in the same breath adds that I must share atleast 50% of expense for repairs.

NOTE: I had personally appealed and then sent written request to all tenants to not to stop me on way and come to my office which is in same building for any discussion.

points to ponder:

1.I have been alone paying building taxes which are in thousands.
2. I am alone paying for common electricity bills, maintenance etc..
3. I am alone spending on maintaining common areas, terrace, and several amenities and have spent in lacs if last few years.
4. The shameless tenants pay only Rs 40/- p.m. but use much more the room, common toilets and parking illegally. Tenant Chadha does not even pay rent and has illegally settled a trespasser in building.
5. All hungry government staff specially BMC keep coming on some pretext and seek alms.
6. Even a child knows that building constructed in 1947 will now need major repairs and regularly.
7. They know landlord the shelter provider has no income to carry out any repairs atleast major and in their own rooms. Though I have been doing some urgent repairs of common areas as I know they will rape the building but will not contribute to maintain same.

Options:
1. Tenants have options of keeping good relations with landlord so their is team spirit but unfortunately all good tenants have left the building ( of course after taking market rate compensation) .
2. Tenants have option of persuading and cooperating with landlord for going for redevelopment but instead they do arm twisting by asking 3 times the area in return for giving cooperation. Why should a land lord succum to their blackmailing specially who are giving all sorts of abuses and troubles to landlord?
3. This tenant has always been on the side of most mischievous tenant and now seeks 50% share to repair his house which he used  for 60 years by paying only Rs 40/- p.m..

Rent act laws r reasonable and just but judiciary is sick and delaying so approaching courts is like calling for more trouble and letting advocates etc  loot you without giving any thing in return.
