it is best if the current manager can reach our via phone/text/email/letter, however they communicate with the tenants about a week before you approach the tenants. 

I had maybe 6 different contractors on my last project and I spent a whole lot of time on the phone just trying to get people to get out there. 

You're either knocking on doors, putting out flyers and signs, making phone calls, connecting with property owners online, or a combination of it all.

Long story short we have had several different complaints all that we document via email, texts, and phone conversation with the original gal who signed the lease.

I’m in the midst of closing a few deals with mobile home investing and would like to invest some of the profit into starting up an Airbnb.

If so, what are they actually doing about it beyond just billing you for getting a phone call?

For our smaller number of doors (35) erentpayments.com and its reports works best for us.BTW I strongly suggest you move all tenants to a google voice phone number. 

Give them the price you want and then hear the phone click.

The exact wording in my email to my tenant:"If you're unable to get it down to a more comfortable temp, I'll be happy to have someone come out to take a look at it, in which case I'd ask that you please try contacting [HVAC repair person] from [name of HVAC company]: [phone #]."
