Brokers asking buyers for a pre-qual letter or proof of funds is a 'trick question' that functions as a very effective 'litmus test' by the broker to find out if the buyer is inexperienced. Brokers are flooded with lots of inquiries, sometimes over 100 on each deal. They don't have time to interact with everyone so need to disqualify most of the inquiries. Ignoring inquiries and waiting for serious buyers to pick up the phone and call is one way they screen buyers. And asking for proof of funds/pre-qual letters is another. Experienced buyers know that this is a trick question and they don't provide either one. Inexperienced buyers think they actually have to provide this when they don't. Don't get sucked into the trap of answer/providing this. Everyone with any experience knows, as do the brokers who are asking, that proof of funds and bank pre-quals mean absolutely Nothing. The 'experienced' answer is to push back and 'call their bluff'. What the broker is trying to determine is if you are experienced or not. If you stand up, push back and talk like you know what you are doing, 90% of the time the broker will quit asking for stupid proof of funds and engage with you as a serious buyer. So, my advice is stop falling for the trick question, it only confirms that you are a newbie.
