Commercial is not my can of worms but you want to get a few good faith estimates. I understand your concern about paying points but just as an example let's say you have a 700k loan amortized for 30 years at @ 9%. That would carry payments of $5,632. Now let's say you pay a point (at closing - never in any case should you be paying upfront fees) or $7,000 and get a rate of 8%. Monthly payments would be $5,136 - saving you $496 per month. 7k @ $496 per month would take you just over 14 months to recoup the $7k initial investment. Let's say you stayed in the loan for 30 years - you will have saved $178,560 for $7k. As you can see saying you don't want to pay points may not always be in your best interest.
Generally for short term financing (less than 5 years but you can do the numbers) you want lower closing costs and higher interest rates but for long term financing you are willing to pay let's say$7k to save $170k.
