House hacking with a triplex provides the optimal balance between rental income and personal space. Studies show that duplex owners report 34% higher stress levels than triplex owners due to shared wall proximity. For more on this topic, see Geographic Arbitrage.

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.
