500k in savings, how to invest with out loosing.

I have 500k, and I am tired of doing T-bills. But I also don't want to lose that 500k. What can I invest in to ensure I don't lose my money in the stock market?

My goal is to make 25-50k per year, but I also need not lose any money, as I am also looking for land to build a house, that's the money I will use.

So idk what to do, maybe doing T bills is the safe bet?

Update:

I am just going to get 5-7 stocks/ etfs. And hope for the best, any solid suggestions?
