If you were to heavily insulate the inside wall of an old double/triple wythe brick building the external wythe may no longer dry out thoroughly and be subject to excessive freeze - thaw damage.The best way to insulate old brick buildings is from the outside - which has the added advantage of turning all that brick into a thermal mass in the conditioned space ... alas, most owners of old brick buildings are unwilling or unable (due to historic designations) to insulate over the external brick.There are some informative studies and papers by John Lstiburek and the folks at Building Sciences Corporation about dealing with old brick buildings.

Their advice is generic and made to entertain a mass audience. 

Maine, New Hampshire, northern Mass are really underrated areas

Mass housing shortages, booms in price inclines, this sounds like the story my Grandfather told me of when he got back to the US from Japan with a fist full of war bonds in his hands, and bought his house for what at the time was an insane all time high price of $8,700.00.

Not sure how exactly they would do that but I can think of a few ways that would help prevent mass foreclosures.

I am not a mass flipper and haven’t purchased 100s of units.

@Louis Siano Talk to a local bank and ask about Mass Housing. 

You need an agent that can source property and get you in front of the right ones before the masses show up. 

Perhaps certain neighborhoods will be worse for wear, but not a mass exodus.  

Across the country there is a veritable army of companies who pivoted on a dime, re-tooled, invented, and now are in the throws of mass production and mass hiring for there now business of various PPE production.
