You'll see a lengthy September 2017 ordinance about rent control, and then a March 2018 ammendment to this ordinance, bumping it from 4+ to 3+ if not owner occupied.

Without having to analyze the numbers I was able to respond with a reasonable explanation of why an investor would not be able to pay as much as owner occupant for his house.I guess people who eschew the 1% rule would go back and spend an hour putting together a detailed analysis to answer that question.

The original deed listed multiple owners and percentages including her 8% interest, and now myself and the other owners want to sell the property---how do we get this retitled into my account (or my name) in order to facilitate the sale?

I've always gotten a signed "authorization to release loan info" from the owner on record. 

Here is an article i found with a simple google search: about $5000 but i thought quiet title in georgia was actually higher.Tax Deed Services For Owners of Tax Deeds - Gomez & Golomb LLC

Are the other parties to the agreement the property owner sharing the well and maybe an HOA?

I also understand typically the lease is between the property owner and the tenants. 

Some like to do owner carry and stack up the passive monthly income etc.

Are you sure you can borrow the $500k of the $1M purchase since you won’t be the owner?

If there issues that need to be worked out with the 6-unit property, I would utilize that as a negotiating tool to work out a seller financing strategy with the current owner.
