Depending on your market, there may be public information. 

So it's more a "requirement" of "the market" than a requirement of the loan program. 

Is there a good public source for transaction history?

How do I find public reits for non accredited investors?

@Alex Vick you should interview at a few places, and find one with the best training program. 

They operate like a broker (lots of outlets, which means more programs than a bank and often lower rates), but they are the direct lender (which makes them a bit easier to work with and more predictable/reliable compared to a broker). 

That case also gave us a multifactor test to determine if a note is a security based on the motivation of buyer/seller, plan of distribution, reasonable expectations of the investing public, and other factors that reduce risk. 

The private listing is called a "pocket listing" when a broker lists a property, but does not advertise it to the general public.

The lender says the loan program they go through isn't really geared towards people investing but rather purchasing family homes to live in.

East Boston, Mattapan, and Roxbury are all part of a pilot ADU program through the city of Boston which has potential to add upside to an owner occupied deal.
