If you give someone over 19% membership interest in the deal, the bank will usually require a personal guarantee from that individual. 

I personally am not investing at the moment. 

We purchased an RV last year under our personal names that is primarily used for business travel.

Quote from @Zach Howard: I think it's probably better to hold real estate in an LLC than in my personal name.

The key is to identify personal property from real property.

I'll let others chime in on their experiences, but from a motivational perspective, I think attending live events and getting the "conference high" is something that only happens through in-person connections and being in the same room with investors who are eagerly pursuing their real estate/financial goals. 

You might be able to get around the fact your entity owns the property by either transferring the property back into your personal name or by some personal guarantee or cross-collaterization agreement.

While some strategies may work here, those strategies might not suit you.I don't personally do MTR, STR, co-living, or other nuanced strategies.

Quote from @Basit Siddiqi: I personally would not buy real estate with a retirement account.There are just too many headaches that are not worth the potential increased return.Some headaches when it comes to investing in real estate with a retirement account1) LTV values are less and harder to find lenders.2) Potential to sell or partially distibute the property if you have to do a RMD(Required Minimum Distribution)3) If you run out of cash and have to make a major repair, you may be out of luck and have to sell.4) Having to potentially worry about UBTI(Unrelated Business Taxable Income)I would personally invest in stocks/bonds/notes with a retirement account.I buy deals with cash and use a ROTH SDIRA so there are no RMD's.I buy at huge discounts to retail.

Another benefit is it is much easier to diversify into multiple markets, asset classes and operators.Just wanted to share an alternative - often active investing is the way to go, but it really depends on the person and it is important to know that there are passive ways to accomplish your financial goals.Good luck!
