I have a term in my (Washington State) group lease which says somewhat unnecessarily that if all parties agree then a one-page Extension Addendum will be acceptable and will modify the current lease no more than by changing the end date by one year and the rental amount by the change in the Zillow rental index for the area, and that such an extension should be signed a month before the end of the term of the current lease. 

The day before the closing date (May 30th) I was told that the buyer's financing could not be approved for the FHA loan due to a judgement on his credit.

It will seem like an expensive month for your tenant because they will be paying $1,500 within 15 days, however, they have to keep in mind that they CAN NOT just have 1/2 a month for free because they want to change the rent due dates.
