I look at a lot of things and take weeks to months to do due diligence. 

What would be a reason for you to back out of a deal during due diligence?

also, after they accept the offer, is this when the due diligence period begins? 

I did tons of due diligence on multiple TK providers and PARC was the only one who checked off all the necessary boxes.  

This may include conditions on due diligence, limitations on further seeking other interested parties or confidentiality.]

There are a number of steps including due diligence. 

They have a very ambitious timeline and I know this is just the due diligence period so we are far from it being a done deal.

So one way to try to get ahead of this issue is to bring your contractor in during due diligence and have him give you a worst-case scenario read on the property.  

For transitioning, please do your due diligence and look to see if contracts are on month-to-month or yearly, and when each expire.
