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.

Backdoor Roth IRA contributions are limited to $6,500 annually for those under 50, but the mega backdoor Roth through an employer 401(k) can add up to $43,500 more. Not all plans allow this, so check your summary plan description.

I respectfully disagree with point number three. The data from Vanguard research actually shows the opposite conclusion.

This is exactly what I needed to hear. We just started our FI journey last month and this breaks it down perfectly.
