Hi Joseph, In this matter you must consult with a property lawyer. He will give you the right idea of the property tax and whether the building is legal or illegal. Nobody can help you better than a property expert.
I think Sankalp is right, However, most such lands in Thane do not have clear ownership title. The landlords leased out their plots in return for a financial consideration for 60 years to 100 years. The temporary ownership of this land now rests with the lessee, who constructed the chawls or buildings on these plots and thus created third party share on this land
First of all i would like to tell you the calculation of old property. These are the simple steps which you have to follow while you are calculating property tax of an old building in Thane.
(Capital value-based system) Capital value = Base value x Built up area x Use category x Type of building x Age factor x Floor factor
Undoubtedly, Thane district is the Wild West as far as the construction/realty industry in the Mumbai Metropolitan Region is concerned. Illegal construction has flourished as successive governments have been merciful and as authorities like corporation officials and policemen, their pockets well-lined, turned a blind eye. In return, poor buyers will have to suffer a lot during redevelopment is concerned.
