401k to fund property

[Cariza Abinguna]

Hi guys! I have a good amount of money from my 401k from my previous employer. I didn't do anything to it once I left my job back in 2020 so its just sitting in my account. I would like to cash it out and use the funds for purchasing properties. I am aware of the penalties and taxes which I'm okay with. I just think I'll have a better ROI using the cash now to buy more properties than just letting it sit there. I was just wondering if anyone have a better idea or have suggestions and recommendations how I can utilize my 401k money to use for real estate. I heard of SDIRA? but I dont fully understand it. Can I roll over my 401k to SDIRA?
