I’m 50 and have lots of land. How do I reinvest for my retirement and new family?

My name is Aaron. I’m 50, and I am in the informal employment sector. I don’t have academic qualifications, but I was able to acquire several properties in my younger years. Currently, my salary is Sh60,000, while my wife earns Sh35,000. This is my second marriage, after a divorce from my first wife. Thankfully, my first family is financially independent of me. In my current marriage, my wife and I have been blessed with a two-year-old son and are planning for another one soon.

Here is my financial status: I currently have no loans. My Money Market Fund account holds Sh7 million. I have two prime plots in Kiambu, valued at Sh7 million and Sh5 million, respectively. I also have five plots in Kamulu, all valued at Sh5 million. Additionally, I own a half-acre in Juja Farm and another half-acre in Kiambu, valued at Sh2.5 million.
