what's fair to expect from a title company/closer?

I wanted to ask a quick question of other real estate investors/realtors/mortgage brokers on here.

What is a realistic timeline for a title company/closer to process and handle a closing?  If the lending process moves quickly (ie you are paying with cash or have a hard money lender that moves fast), how much time is fair to expect from your title company/closer?

I was getting a lot of push back from the company I'm working with over a two week close, and wondered if that is common.

Any advice?
