Anecdotal story:  I just walked an industrial property that we are in contract for (single tenant, NNN lease).

Long answer, they can walk you through anything that could possible come up and they provide more protection with their license than you do as a sole buyer.

If I list with a realtor for a discount and pay 100k in fees (commission, taxes, closing, deed, etc.) then it just hurts my ability to walk away since there is a mortgage left on the property, though much less than either asking price.  

From personal experience, things can change A LOT when you do you walk through.  

You need a registered investment adviser or financial broker to walk you though the DST market place. 

I am not a "full time" investor, so I don't want to be spending a lot of money on direct mail marketing campaigns, or spending hours on courthouse steps, or walking down the street knocking on doors.  

This time I did, and told him since he's so clumsy. he's not allowed to walk around my shop unescorted and have to stay in the waiting room when he does.

You might call the county clerk to walk you through what paperwork needed and the process.

Most walks I have paid for were around $100 in Texas.

It walks you through items about self-managing.
