Would you use your tenant as your lender?

[Henri Meli]

I own a commercial building and one of my tenant is a local commercial bank. They occupy about 10% of my total space. They are also the major anchor to my building, as their large signage is on top of my building. They are a solid bank with many offices in the area. 

I'm considering a refinance and the tenant has asked me casually to consider them. I haven't had any in-depth conversation with them yet.

I'm curious to know what are some of the positives/negatives of this type of relationships. What would be the advantages? What would be the pitfalls? 

Why would I want to do that? I believe that a solid relationship with a local established lender is really a good thing.  

Drawback: I would need to submit to them all the rent rolls from all my tenants and they would know how much I charge everyone ... etc.
