All the best,
I will not elaborate on what has been answered. They are all good and helpful. My comment is that just in case you might want to get the agents to print up an " extension of closing date" for both you and the seller to sign to keep the purchase offer terms in place. If the closing date is not meet than the offer will go into default if there is not an agreed upon extension.
Wishing you the best!
It's very likely that closing slots with the title company are limited. End of the month is always swamped, so they may want to wait until they know for sure before they book your closing. Not to mention that your lender (if you need a mortgage) probably needs to have a firm closing date before they can send documents to the title company. It's not as easy as just snapping your fingers and boom it's ready to close. There's a process that goes into every closing.
In any case, it shouldn't be long and you should hopefully be able to close within a matter of days.
The finish line appears to be in sight,so good luck!
