Haven't been depreciating

[William Reed]

I recently found out that I had not been depreciating my rental property in Fayetteville, NC. We originally purchased the house in 2006 and have been renting it out from 2010 - present. We would like to file a change in accounting method from impermissible to permissible via Form 3115 on our 2016 tax return. My question is, how does the IRS refund or credit the depreciation costs back to me as the tax payer? Do we get the full amount of the unclaimed depreciation?
