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.

Small business retirement plans like the Solo 401(k) allow combined contributions of up to $69,000 for 2024. Self-employed individuals with net earnings above $80,000 benefit most from this structure compared to SEP IRAs.

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

I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.
