Typically most sellers will look at a contingency because there is little risk IF they are allowed to leave the home on the market and pursue other offers, which may not be best for buyer but would be for the seller. Perhaps you could negotiate a period of time where they wouldn't try and sell it to another buyer that was ready and able to close on the home. All you can do is ask.
If you need anything else, feel free to contact me any time. Buying and selling is always loads of fun! (well, sometimes).
