You have to remember that brokers are incentivized by closing a deal and in order to do that they mitigate risk in various ways...one would be to see upfront if someone has enough money to transact and if they don't they won't waste their time and move on to the next even if the buyer has other means of bringing capital in (it complicates the process for the broker and introduces risk of a deal not closing). I've seen many brokers that don't understand the concept of search and I typically don't engage them either as it's fighting an uphill battle. I've gathered letters of support from SBA lenders, I know of others that have gotten letters of commitment from investors and some brokers still don't care. You need to decide what your strategy is when faced with a broker like this...either continue to engage and potentially get nowhere or move on put it behind you and find the next deal.

Broker relationships can be difficult, as they are in the banking industry and no on in the industry really likes you to shop around. Have you considered asset based loans that usually don't require as much information?
