In conjunction with an attorney you should consider using a buyers agent. They can do all the coordinating and running around for you at no cost to you. (commission to the buyers agent is paid by the seller)
Regardless of whether you use an attorney or an agent to write the offer, make sure the contingency is written in a manner, so that if you house does not sell your are not obligated to purchase the new home and you deposit money can be returned to you.
You can certainly have an attorney write the offer, but you will be much better served by an agent who has a better understanding of the local real estate market and can negotiate for the best price and terms FOR YOU!
There is no fee to you for using a buyer agent and you can actually SAVE money by doing so. Feel free to contact me directly if you'd like to discuss this further.
All attorneys do real estate, but you often learn too late that they aren't real estate specialists - especially in the case of a FSBO: in MA, there is usually a reason the property is not in MLS, and sometimes it is complicated.

I would never advise someone to accept a contigency where the person was going to attempt to sell their own home or price it above market value.
Make sure your home is staged and ready to go at full potential. Have the repairs done now and put it on the market first with a contingency to find suitable housing.
