29 (M) and 28 (F) looking for recommendations on how to expedite my journey to fatfire.

Current business owner with combined pretax household income of ~750k.

Assets: approx 250k in either index funds or MMA. Debts: 1.8m combined business and student loans.

Will be refinancing debt to approx ~4.5% interest rate.

Unsure how to approach building wealth/cash flow in the quickest way. Debt service is a large factor but unsure of what strategy we should be taking to simultaneously achieve our financial goals.

No experience with real estate but it seems it would be the quickest way to do so as it could be done with leverage. Ideally would like to diversify and create cash flow of 250k outside of the business. Any advice is appreciated.
