Mortgage Buying Groups: do they exist?

[Chris Abkarians]

Hi all,

This is a bit unorthodox but curious to hear some thoughts. I reached out to a dozen lenders in Boston to find the best rate for my own mortgage. Many of my friends were looking for mortgages at the same time. So, we asked a few of the lenders if they'd give us a discount if we got 10-20 borrowers to go with the same bank. Surprisingly, 2 of them said yes and now we're bargaining on price.

This didn't seem all that difficult to do, so I'm wondering if this already occurs at a larger scale? Are there any buying groups I could perhaps join to find an even lower rate?
