Calculating depreciation without a breakout for land vs bldg/impr

[Jane Hankins]

I bought a short term rental property in Walton County Florida. My property tax assessment doesn't show a breakout for the land vs building/ improvements. I've used that breakout to help calculate depreciation on my California properties. I'm a bit confused on how to handle depreciation on this one. Any ideas? I'll talk it over with my CPA closer to filing time, but I'm curious for some insights now if anyone can share.

Thanks!
