Are you using a bank or credit union? I bought and refinanced my first home through a bank... It was like that.
Now I will only use a mortgage broker or direct mortgage lender (Rocket Mortgage, Mr. Cooper.) Way, way, way easier. I just got my closing disclosure yesterday from a purchase through Rocket Mortgage. Easiest process ever. Upload a few documents (paystubs and taxes) and they pulled all of my bank records. Never going back to banks or credit unions.
My last few before that was a mortgage broker buddy from a few office suites down the hall. He told me what all to get, I handed it to him a couple days later. His staff made the copies and handed the originals back. A few weeks later we were closing.
With the bank it was one document at a time and they never had the courtesy to give a heads up... It was always we need this today, or there will be delays in your closing.
