@Jay Hinrichs I am going to have my programmers create an app to take your text and convert them into emails just so you can acknowledge them.It should only take a few days so after that youll be up on the latest communication wave.  

To the extent permitted under this Agreement, each Co-owner hereby makes, constitutes, and appoints ____, a principal of _________, the property manager of the Property, with full power of substitution and re-substitution, his true and lawful attorney-in-fact for him/her and in his/her name, place and stead and for his/her use and benefit to sign, execute, certify, acknowledge, file and record all instruments that may be appropriate in connection with this Agreement and the Property, including without limitation, leases, amendments and documents relating to the leasing activities of the Property.

The reason for this is flips are subject to self-employment tax and an S-corp can minimize some of these taxes.However, you have to acknowledge that having an S-corp adds fees(such as setting up an S-corp and annual tax filings). so it may not be advisable to set one up unless you expect to make $40,000 in flip income.Holdings rental property as a sole proprietor vs inside an LLC provides no tax benefits.

The next day I sent in a request for cancellation according to their requirements and received an acknowledgement of their receipt for my cancellation.

And yes I agree with you in that the net to HUD is the focal point on just about every page of every offer, counter, rejection, and acknowledgment through their systems.

It likely contains verbiage to the effect of: "The Seller herein acknowledges that it is the intention of the Buyer to effect an IRS Section 1031 Tax-Deferred Exchange and that the Buyer's rights under this agreement shall be assigned to [insert name of Seller's chosen intermediary here] to facilitate such exchange.

My guess is that they won't leave but will at least feel like you acknowledged their situation.

Looking back, I must acknowledge that personal branding and social media played a huge role in my success.

I know many are passionate about the real estate practice, I acknowledge that and am knocking it! 

An addendum to the contract executed by the seller releasing the straw man and acknowledging the new buyer cleans up the contract.
