I am always happy to chat about hard money - and I am biased, but I think I am an excellent communicator!

A lot of maintenance issues are repeated again and again on all the properties a PMC manages.So, a PMC has pretty good idea of what many issues cost.

i also had HVAC mystery issues in my first duplex when we house hacked it.Regarding the Daikin Mini Split - I have one in the 3rd story of my current home and it seems to work great for us. 

A few issues I have faced:1.

I would love advice from the community on this issue.  

I've worked with several loan servicers, and no matter who you use, it's not fun setting it up, but I've had easier success communicating with OnePoint.They have a login portal to track payments etc, like you mentioned. 

It would be wise to rectify it before transfer of title so your starting off clean and hopefully won't have any issues when you go to sell down the road. 

My tenant is also nonresponsive to all communications so they may not even show up at this point.

Within a residence there is a presumed right to privacy and installing cameras by you or your tenants can bring you legal issues.  

Document all your efforts, including repair invoices and communications, to show you’re acting in good faith as a landlord.
