How will this affect rental rates in my town?

[Sylvia B.]

I found this notice in this week's newspaper:

It goes on to explain various parts of the new plan, but then at the end it has this:

Note the part I underlined in red. Current rent for a 3BR apartment in low income housing is $350, and it's going up to $702. Wow!

So I have no idea how "low income" housing works. When they raise the rates like this does the tenant actually have to come up with the extra money, or do we, the taxpayers?

Is this likely to boost SFH rental rates in the area?
