Real estate attorneys handle title and closing.Keep in mind you can invest no matter what profession you have, just like you can help people feel better and live healthier lives without becoming a doctor.

Remember, you cannot personally benefit from business with your SDIRA, so I'm not sure what this structure looks like or how you'd avoid that, but maybe I'm missing something here.You've got a lot of options and ways you can go, so you should figure out what interest you/you'll be good at, pick a goal and go for it rather than getting too scattered.However, one thing I will advise you - it's generally a bad idea to invest (rentals, flipping, notes, etc) with your family's next meal. 

We don’t pocket the entire $500 by any means, we let our company pay for our health insurance, cars, gas, car insurance, lability insurance, meals, phones, internet, accounting, legal expenses, etc, etc.
