Land value for taxes.

[Josh Lonnquist]

I'm looking for help in determining the value of the land of my Indianapolis rentals. In order to calculate my depreciation I need to subtract out the value of the land from the total cost of the property but I don't know where to get it from. it isn't listed on my property tax statement. is there a rule of thumb I could use? My rentals are in C class neighborhoods. One property is on North Capitol Ave. and all are similar to that one. Any suggestions are greatly appreciated. Josh
