If offer is accepted, you have 48 hours to submit the wet-ink paperwork to the regional office (PA is the one for me), along with the EMD stated in the contract ($1,000) If you choose not to take the property, you are not bound to anything, so you could walk away without penalty3. 

Also, I like when tenants are there when doing a walk thru, I like to see if they talk about their landlord, it says a lot about them.
