@Kevin King That can be a reality, but usually everyone is looking for/at the same things. If you're working with a banking institution, then they might be only offering you "portfolio products," meaning it's their own loan product and they determine all the details, guidelines, and requirements for their own loan program.
However, the vast majority of mortgage lenders are either a direct lender (like me) or a broker. And while they have ACCESS to some portfolio products, the majority of what we are working with are standard guidelines from Fannie Mae, Freddie Mac, FHA, or VA. And those guidelines are the same for every lender in the country if they are going to sell that loan to the respective agency (this is probably 90% of all originated mortgage loans in the country). So Complicated answer simplified, MOST of the time lenders have the same guidelines/requirements as every other lender, and it's just a matter of how knowledgeable and "plugged in" the specific loan officer is.
Hope this helps. And yes, I am in SoCal as well!
