Don't put two properties in one LLC.  

@Mike DymskiLender will get a deficiency judgement and go after the other equity in those propertiesSo let’s say after foreclosure or traditional sale the borrower owes $400k, lender will get a judgment and slap it on those other properties and take the equity from thosePeople think “oh well they had them in different entities” - that doesn’t matter as a personal guarantee means they guarantee it and the lender can go after everything that person has including all their other LLC’s.

We are going to create an LLC.

I intend to buy them 10-30% below market value through my LLC. 

They can purchase the property in their LLC, using SDIRA or 401(k), as long as they follow the rules.

Put them on as a minority member of your business entity/ LLC and you'll have no problem using their funds with just about any lenders.

Working to get the Quitclaim Deed under my LLC.

I have a property in CA that I want to put into an LLC.A lawyer advised me to register my LLC in Nevada and then complete the foreign entity process for the LLC to also be registered in California, where the property is. 

Usually I would think it's easier to have the LLC where you are.In SC I can create a LLC for $110 and not have any annual fees to maintain it.

The plan was to open an Ohio LLC that would be owned by the Holding LLC and put the property under that LLC.
