It's a matter of investigating the cost and seeing if it's worth it.

Every unattended death (no one else present) is investigated.

This is a great place to learn and further investigate investing in real estate.

However, this is a serious violation on the part of both parties and I am sure the Housing Authority Integrity Officer would investigate.

They are actively investigating this. 

For extra formality, put it on a nice document with your letterhead.Re: Non-Binding Letter of Intent to Purchase Real Property Located at [Property Address]Dear [Recipient's Name]:This non-binding Letter of Intent ("LOI") is submitted by [Your Name] (the "Buyer") to [Recipient's Name] (the "Seller") with the intention of setting forth certain preliminary terms and conditions for the proposed acquisition of the real property located at [Property Address], inclusive of all improvements, appurtenances, and fixtures thereon (the "Property").Purchase PriceThe Buyer hereby proposes to purchase the Property for a total consideration of $[Amount] (the "Purchase Price"), which shall be subject to adjustment based on the results of the due diligence investigations and final negotiations.Earnest Money DepositContingent upon the execution of a definitive Purchase and Sale Agreement (the "PSA"), the Buyer shall deposit earnest money in the amount of $[Amount] (the "Earnest Money") into an escrow account designated by the mutual agreement of the parties.

I will definitely put your suggestions to work and investigate multifamily house rentals here in MA. 

Investigates rents in the area and calculate if the rents will cover the mortgage when you leave.

After investigation with the community management team, I made the decision to close both accounts for various violations of our forum rules.

So again, I'm not passing judgement on the actual program you are investigating... but will tell you that there are few secrets in the real estate / wealth "game".
