I have a question regarding a 1031 exchange when there is a boot and I have been using the deprecation deduction.

Here is my example. I sell a house for 700,000 and I purchase a new one at 680,000 giving me a boot of 20,000.  I deducted about 200,000 in depreciation over 24 years.  

What might the depreciation recapture amount be on the boot (20,000).  I understand I need to pay this tax in addition to the capital gains taxes from the Feds and my state (Oregon).

Thank you!
