Commercial rehab loan - what to expect?

[Adam Craig]

I am in negotiations for a 5 unit office building. In my single family business I used hard money for purchase/rehab then I refinance 3-6 months after purchase. 

This strategy wont work on the commercial building because rates are too high and I wont be able to refinance for 1-2 years after I get it stabilized. 

What are typical terms for a bank rehab loan? Below are the rough numbers I have worked out on the purchase.

Purchase price - 275K

Improvements - 80K

Seller willing to carry the 20% down payment.
