Getting a proof of funds from HML to go in offer: takes too long?

[Ashley Benning]

This is the second time I've gotten to the offer stage on a fix and flip property. In my market, Los Angeles, these properties go FAST. It was listed on Thursday, I saw it Friday and emailed a few HMLs to ask for proof of funds letters to go in my offer, and I need to submit my offer tonight and I haven't gotten any letters back. I've already been pre-approved. Aside from predicting the future, how can I change my process so that these letters come in a more timely fashion? My realtor says if the lenders aren't getting back to me on the weekend then they aren't good enough to work with me. But I also know these are people who need a work/life balance. All I need is a letter stating: Ashley is approved to offer cash up to x amount and a quick close on property 123 Main Street. That's it! Any suggestions?
