I do not know if Auction.com is still owned by many of the major banks, but it used to be and that was how they cleaned out their REO properties en mass!

While some might do this, I don't believe it will be a widespread problem.There are three reasons why this will not happen en masse:1) Capitalization: The landlord is typically well-capitalized, with 6 months of reserves for precisely this type of situation.

However, I do not know what the tenant laws in Mass are so it might be worth either calling a local office or doing a basic google search to see if their are any details such as needing something to be notarized, or if there is a specific state template that needs to be filed. 

Funds or syndicators most wouldn't allow mass cash calls from investors to get their liquidity back.

I am located in central Mass.

I don't like mass emails.

@Brian Ly there are several RI and Massachusetts folks here on BP :)If you mean in-person meetings, RI has the RI Real Estate Investors Group and Mass has several groups throughout the state.

Are there any apps that provide landlords and tenants to have a direct line of mass and individual communication?

For investors, (unless you're doing mass volume), it doesn't make sense to pay full commission...For average Americans who do 1-2 RE transactions every 10-20 years...they don't know any better.

Is the location able to support a downturn in the market or will people start to mass exit the area?
