Help with underwriting

My home is being refinanced. It appraised with 20% equity, I have a credit score in the low 800's, low debt to income and high enough income. I have a full kitchen upstairs and everything but a stove downstairs, so the mortgage company wanted to make sure this wasn't a rental of the upstairs and downstairs. The stove was originally downstairs and they forced me to move it upstairs, even though it was more convenient for us downstairs.

I don't know why any of that should matter, but regardless I do live there. I'm starting to get irritated with the hoops they are making me jump through, what's a reasonable level of things for them to request of me. My broker mentioned I should write, almost an apology about why I receive some of my packages/mail at my parents house.

Anyway, I don't want to be prideful here, but along with some other minor annoyances, I'm almost ready to walk and wanted to know what is a reasonable amount of things to be requested to prove you live where you actually live.

I'd also like to know, that if this goes south and they deny, do I have any recourse against them, as it only has this problem in underwriting, but there is only a certain effort that I will put into proving that I live in my own house. I'm not going to beg someone to take my money either. It's been 4 months of hoops and I want to make sure my perspective is correct.

Thanks for reading.
