Capital Gain Tax on out of state rental property

[Inna Hurin]

Here is my dilemma- do a 1031 exchange or sell, pay taxes and use funds for our remodeling project. 

We are currently in contract to sell our rental property in CO (we live in CA). 

Bought it for $411K, selling for $460K, owned for 1.5 years. 

I claimed $10K in depreciation for 2016

I anticipate $25-30k in closing costs

My questions is how much tax will I have to pay in capital gain and depreciation? Will I also have to pay CA & CO tax? I know CO will withhold 2% of purchase price...where would that go and how can I get it back? 

Any feedback is much appreciated!
