Key Terms Explained
1031 Exchange
IRS rule allowing you to sell an investment property and buy another without paying capital gains tax — as long as you follow strict timelines.
Capital Gains Tax
Tax on profit from selling an asset. Long-term rate is 0%, 15%, or 20% depending on your income. Plus state tax on top.
Depreciation Recapture
The IRS taxes back the depreciation deductions you claimed at 25%. This is separate from capital gains tax.
Cost Segregation
Accelerates depreciation by reclassifying components to shorter tax lives — generates large year-1 deductions on new properties.
