I believe with her discounted rate I will be charged $26/month for my Quickbooks account.

makes about as much sense as me standing in McDonalds drive thru blocking traffic demanding everyone stop buying burgers so I can force McDonalds to discount burgers 20% due to lack of buyers....All these people howling there needs to be more rental units so rents are cheaper. 

Sort of split the difference.2) Offer them moving expenses and/or to return their entire deposit if they decide to move out3) Discount the rent while the renovation as going on since it will surely be an inconvenience

If you have only 1 month supply everything sells and sellers don't have to offer much discount.
