She was pretty good at communicating at the beginning (we began talking with her around the time we started talking with Michael), but she was not good about responding to emails and we pretty much had to call her to get a response. 

I called and emailed back but nobody even responded to my request.

Hey Dee, BiggerPockets support is super friendly and quick on their feet. https://www.biggerpockets.com/contact-us#customer-supportScroll down to the bottom of the page there's a contact form you can fill out and they typically respond in a few hours. 

Thank you for taking the time to respond!

If not (or if they fail to respond), I send them a 30 day notice to quit when I'm 30 days out from the end of the lease - in accordance with the Michigan eviction process.

Meaning they solely focus on finding guests and responding to their needs. 

How fast do they respond to tenant issues?

Many times they will respond. 

I would really appreciate if you can respond.

We've also been trying to reach out for 1-1 coaching and you haven't responded to us for months.
