If the seller feels you did this intentionally, they may not release your earnest money.

It would be odd/silly for this contingency to run all the way up until the closing date, but I don’t know how you guys do things there.At the least, I’d communicate with the sellers letting them know the sale of your house has fallen through and it seems highly unlikely you’d procure another buyer and close by your contract date....doing a mutual release now would be beneficial to the seller so they can get their house back on the market.

In my experience most brokers will release you if you are unhappy.There may be a fee.

Maybe a portion, but most is held in escrow and released based on completion with inspections needed for a draw.If the repairs aren't completed as stated, then the money may not be released.If the borrower defaults on the loan, the lender may still have funds left to complete the rehab.Hopefully that helps...

I'd recommend having them sign some kind of release of information document to ensure they know you'll be doing all those checks.For advertising utilize all the free options you can (e.g.

This indemnification agreement does not waive Owner’s Agent’s duty of care to prevent personal injury or property damage when that duty is imposed by law.Resident May End Lease Early:Resident may end this lease before the end date of the lease or any renewal term only with written permission from the owner and only if: (A) Resident gives owner minimum written notice as defined in the lease end notice procedures, AND (B) Resident pays owner a minimum Early Release Fee of two months’ rent, plus utilities during the required notice period, OR (C) Resident continues to pay all rent and utilities until the end date of the lease or, Owner secures a new resident to take the place of the current Resident, whichever occurs first.

If the remaining tenant can't do that then let them break the lease pending any early release penalties you have in the lease. 

Let her know you will release her from the lease.
