Tenant Interview with National Corporate Tenant?

I'm considering a commercial property with a short term remaining on their lease (3 years). They've been around for awhile and the corporation itself seems to be fine at a national level. There is some amount of competition for this deal and I'd like to put forward my best offer. 

To do so, I'm wondering if it's "okay" to just call up the tenant and talk about how their business is going and any indication they might be willing to give me if they are likely to renew. Alternatively, I could put tenant interview as one of the contingencies. However, given the competition for this deal, I don't want to put little to no contingencies other than the typical financing / due diligence.

Thanks in advance for your thoughts on this!
