Business ProfileforChurchill Mortgage Corporation

I started a mortgage credit approval process with Churchill in September of 2022. I received a Pre-Approval letter and I started searching for a property. I then agreed to Churchill's recommended to do a Certified Approval with them so that when I do find a property my closing would be done in less than the customary 45 days.During the process the loan officer was changed without any communication and I was informed by the new loan officer that I needed to provide proof of no HOA in existence on the property, per their Underwriter. My current property does not have an HOA and it never has. I did all the research that I needed and sent them countless doc's trying to comply that I do not have an HOA, with no success.My mortgage loan was denied due to credit, with no conversation nor further explanation. How do I relay on a mortgage company and their process if they do not communicate with me and simply turn me down when things are not easy for them. Who do I turn to now for help? Am I really not eligible to buy another property? How do I move forward? My credit scores have been impacted by the pulling of their reports yet I am unable to secure a new property and I have no guidance nor information. I have been left clueless and I do not appreciate being treated as an insignificant or uneducated consumer.
