@Richard NguyenI just set up my first SDIRA a month or so ago, so I haven't had enough time to speak too much about experience, but the company I'm using (recommended by my CPA) doesn't charge AUM type fees. 

It depends on the market, the location and the type of single family home.  

What type of properties are you looking for?

Basically types of deals where you will pay the money back quickly, but I have heard of some folks getting financing for longer term with lower rates. 

How do you become that agent who gets these types of leads and therefore listings? 

I have three DSCR loans and that is what I would use for the type of real estate you are describing.

Also for reference, pretty typical SFH flip type properties in my market are about $300k - $400k price tag.  

Hi - you sound like a perfect candidate for the "DSCR Loan" option - its the loan type thats popular wwith investors and one of the big reasons why is the exact situation you are describing - running into DTI troubles. 

She was the type of person who thought that by paying rent she becomes an owner of the property.

Perhaps with a sample property of the type we are seeking.
