It's very clear in the listing that it's income restricted, hence the low price.

This is a standard thing for affordable housing.

Word, the clarity is in the words written in the listing

78k is more than 68% of Americans make.

Although it's not as high relative to the greater Boston area pay averages, or eastern Mass.

(for example, Federal location based pay adjustment is +31% for Boston and Middlesex, and minimum wage in MA is significantly higher than Federal minimum wage)

It’s in the bottom half of Cambridge incomes.

Even with the income restrictions, there will be a lot of competition if the price is limited to $123k. How does it work? Is there a lottery, or does the seller just pick whoever they like best?

A bit poor? That’s weird wording

Would you look at that, all of the words in your comment are in alphabetical order.
