Potential £100k - best way to create income with it?

Hi all - just wondering if anyone has any experience or advice on the best way to use £100k to create another income.

I have the potential to invest the sum, but would like to create an immediate(ish) income with it. I COMPLETELY understand the importance and patience of long-term investments (which I’m currently doing with pensions and stocks and shares), but I’d like to use the money to add extra income. I’m currently considering renovating and flipping houses - Im freelance and have a very flexible and forgiving schedule. But I know that’s a risk (what isn’t) and requires a lot of skill and time (I’m handy and have fitted most things around the house (bathrooms, patios etc). I also know the margins are tight thanks to stamp duty and capital gains tax.

Does anyone have any other suggestions - other than trying poker or prize-fighting, I’m terrible at both. I know there are a 1000 ways to make money, but wondered if anyone had any experience which would be useful. Cheers.
