Depreciation

[Timothy Lin]

I purchased a condominium in 2006 and lived in it for four years. I have been renting it out ever since. I never knew about depreciation until I started listening to BiggerPockets and realized I have been missing out over the past six or 10 years. I have been doing my own taxes on TurboTax, but definitely will be using a CPA from now on. My question is if there is any good advice on how to retro actively claim depreciation or what the best strategy for managing my mistake will be? Though I live in New Mexico now, my property is in Massachusetts, not sure if it makes any real difference.
