JPMorgan Chase Mortgage Complaint

JPMorgan Chase Mortgage department,

Conventional fixed mortgage Settlement process and costs California

I have applied for a home loan at chase on my rental property which is fully paid off. I was approved for this loan and submitted the paperwork required. I started this process in - and they took out $600.00 for appraisal fees on the property. The property was appraised for over $ 300k and the loan amount being asked for is $ 50k. The bank seems to be giving me the run around on closing the loan and when I talk to them they continually state that the loan is approved. I had to pay flood insurance on the property and was told that once I got this flood insurance the loan would be closed then they proceeded to ask for paperwork that I previously submitted saying it was incomplete and do not close the alone.
