A 1031 exchange is a relatively complex transaction where you exchange one property for another to let you defer the taxes owed on your sale (but they are still eventually owed unless you die before eventually selling the property.).   1031’s  comes with many rules, such as you can’t ever come into possession of the money from the closing - it has to be paid to an intermediary.  

I'll play the devil's advocate and say that you absolutely do need your own website/mailing list/CRM/etc because those are the only platforms you can truly own your customer data and engage directly with your customers without the filter of an intermediary stepping in to define the rules of engagement. 

What are your thoughts on turnkey intermediaries such as Norada, Hipster, Rent to Retirement? 

3) I have seen a lot of online Qualified Intermediary, but it's hard to know which ones are credible vs not. 

This is structured much like a 1031 exchange, only the contract with the intermediary is a 30-year interest-only installment sale.

Invest your own money or act as Intermediary for Other Peoples Money8.

If I 1031C exchange the self funded house (Titled to my personal name) identify and a new property, have the $$ sit in an intermediary, can I also use the Self Funded Retirement Trust account to purchase new property along with the 1031C exchange?

I've used Investors Title Exchange Corporation as my qualified intermediary as well. 

The law requires intermediaries (which includes Realtors® who post the property for rent online) who enter into a written agreement with the owner or operator to collect rent or facilitate the collection or payment of rent on behalf of the operator to collect and remit the tax.

Also called the qualified intermediary they are responsible only for the process of the 1031 exchange.
