How do the mortgage brokers on Zillow make money?I'm really confused about how the mortgage brokers on Zillow actually make money and how I can compare their quotes with a traditional bank. I am looking for a 30 year loan on $360k mortage/$40k downpayment. My credit scores are around 800. I called my credit union and they said it would be around 3.5% with 1% origination fee and no points. So that's at least $3600 just in origination fees. I looked at Costco finance and I see 3.5% with "lender fees" of $600 and appraisal fees of $395. When I get quotes from Zillow, my best option right now is 3.375% rate with $390 appraisal fee + $595 underwriting - $568 rebate = $417 total fees. Sometimes I see big rebates and only $1 total fees but still the best rate.What am I missing? If the Zillow quotes were a higher rate than my credit union I could understand that's how they make up for the big difference in fees. Or are there third party fees that I'm not taking into account that are included in my credit union's 1% origination charge that are not quoted in the Zillow quotes? How can Zillow lenders offer rebates and such to get the total fees to almost nothing? I don't understand how they are making money.Any rules of thumb on approximate mortgage-related fees I would expect on a $400k home?
