Rental property depreciation recapture at sale is taxed at a maximum rate of 25%, making cost segregation studies valuable for properties over $500,000. The upfront study cost typically pays for itself within 2 tax years. For more on this topic, see Qualified Opportunity Zones.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.
