An amended master deed generally supersedes and replaces any previous master deed entirely. So, the answer to your question based upon general principles of common law is, "yes," the six lots would not have to follow the original or amended deed restrictions.
However, individual state jurisdictions may have statutes or case law that deviates from general common law. Also, the text of the amended master deed may operate to maintain some or all of the original master deed restrictions. Consequently, there are lots of potential "gotchas" here that I cannot analyze competently without a more thorough investigation.
I am well aware that your goal in coming to Justanswer is to obtain an extremely cost-effective answer to a legal question. Unfortunately, your question falls outside the scope of those issues which can be competently answered easily or with certainty.
So, if certainty is what you require, then your only option is to hire legal representation, because a careful review of the master deeds, and the state laws concerning same will be required, in my opinion. Otherwise, whether it's me or some other contributor/attorney, at this website, or elsewhere -- any answer you receive will be no more than an educated guess.
I hope I've answered your question. Please let me know if you require further clarification. And, please provide a positive feedback rating for my answer -- otherwise, I receive nothing for my efforts in your behalf.
Thanks again for using Justanswer!
