When we got our proof of funds letter from the hard money lender we literally turned it over and submitted it with all the contracts to our realtor, who then submitted it to the seller with our earnest deposit.

Here I have tried both Alameda and Contra Costra counties and both show you the title of the docs that are recorded online but you are unable to get the details of the documents (maybe you have to pay to get them, not sure).

I am in the process of putting together a policy and procedures manual to document everything that is being done in my wholesaling business.  

They interface and work directly with the regular closing entity whether title company or attorney as you choose.California (and more states every day) does have a provision commonly called a "claw back" that involves some additional documentation with your Acct.  

In addition I signed an "Office Exclusive Certification" to Multiple Listing Service of Long Island directing that the property not be published in the Multiple Listing Service This document specifies the exclusive listing runs from 4/26/2016 to expiration date which was left blank. 

We walked the building and submitted our offer. 

I invest heavily in the Tampa area and my buyer's realtor there has never even asked me to sign such a document.

After the roles of each have been established, what type of legal document would need to be put in place. 

The seller has been taking his sweet time to sign the closing documents and I just found out why:  Blaine and Jesse of Vantage Homes submitted an offer to the seller back in April that was $20k higher than our contracted price.  

The Attorney will then contact the IRS as the legal representative of the son, enclose copies of all documents, and request an exact payoff of the tax lien, and ask if the IRS is willing to accept the net sales proceeds of the sale of the property and release the property from the lien.
