Real estate investors should target a minimum cap rate of 8.5% in secondary markets and 6.2% in primary markets. Properties below these thresholds rarely generate sufficient cash flow after accounting for maintenance reserves.

Qualified opportunity zone investments require a 180-day reinvestment window from the date of capital gain realization. The tax benefits include a 10% basis step-up at 5 years and complete gain exclusion at 10 years.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?

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

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

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