Tools or Apps to help me with my real estate journey

[Z. Fourmault]

Hello, I am working on my financial independence plan - my goal is to generate a passive income of $10k a month. I have decided that I want to generate 50% of my passive income from stocks/dividends and another 50% from real estate. Although, still not sure about the split.

I already have:

- healthy 401k and I contribute the max

- roth IRA- I own my primary residence (have a mortgage)

- I own one rental property (with a mortgage), which is cash flow positive

- I also have $30k in savings

My plan is to continue saving and start buying other rentals. I am targeting 3-4 properties in cash flowing markets. Once, I buy them, I plan to aggressively prepay them and increase my cash flow.

I am looking for a tool, app or website that can help me create a financial plan to continue saving, investing and financing properties. Has anyone successfully implemented this strategy? Any thoughts and advice?
Thank you
