Hi,I am an investor in single family homes and am interested to use my equity in them to start investing in multi unit shopping center retail.

Mostly MF and self storage.I bought an industrial property from a wholesaler, paid him a $600,000 fee. 

Here's a list of non-recourse lenders: https://www.biggerpockets.com/member-blogs/2810/50272-list-of-non-recourse-lenders-for-self-directged-ira-and-401k

It will allow you to roll existing retirement funds into the 401k (save Roth IRA) and self direct those funds.  

@Jerry Chilimidos, I see that you are self-employed.

I am also a huge fan of real estate and for the past 50 years there's been a way to combine both.By leveraging a Self-Directed IRA, real estate investors enjoy both the traditional advantages of property ownership and the additional tax benefits of retirement accounts, creating a powerful wealth-building strategy.

By keeping your investments local you may be able to self-manage your properties more easily because you're close-by and already knowledgeable about what's required of you as a landlord. 

I have one tenant who is a god send compared to most, he accomplishes nearly ever repair I need, even did an HVAC unit. 

Remember, the notion of amassing wealth without investing is a dangerous myth perpetuated by self-proclaimed experts.

I think that's a great approach I have a lot of clients who self manage have no issues at all.
