@Jason Scott - Hope this doesn't sound gimmicky when I say this but there has never been a better time to take money off the table in the equities market and shelter it in a solid RE deal. I've included a copy of a prior response on how this works for those looking to harvest capital gains.
$100k Gain in 2019 tax year defers full federal tax on the gain until 2026. In 2026, you reduce your tax burden on the $100k by 15%. So only 85% of the $100k is now taxable ($85k). If you invest after this tax year and up to 2021, you pay tax on $90k. Any cash on cash returned during the investment period is still subject to tax. If you keep the investment for ten years, so you go to sell in 2029, and say that investment is now worth $250k ($150k profit plus $100k initial investment), you pay zero tax on the $150k gain. You wouldn't pay any additional tax on the $100k initial investment because you already paid that in 2026.
Hope this makes sense. Now, you must meet the substantial improvement clause and all IRS guidelines for an Opportunity fund. None of which should be done with out consulting an attorney. Also, this is not tax or investment advice, not meant to be construed as tax or investment advice and you are responsible for doing your own research regarding yours or anyone elses investments. Let me know if I can help further.
