Is it possible to have a phone conversation? 

I think that this is a reasonable request to remove a personal phone number from the forums.

Then make foundation/roof repairs one at a time.

If you get complaints, remind all parties that noise travels, they were warned to be quiet and respectful of their neighbor, and that repeated issues may result in removal.I have an apartment building where the downstairs renter can hear the upstairs neighbor talking on the phone when it's really quiet at night.

Repairs/Maintenance4.

@David Robert - Based on what you're saying it sounds like certain sections of drywall/wall are better off coming out and replacing then trying to repair.

They are responsible for repairing it, whether they have insurance or not. 

See if they answer the phone. 

You can probably try this yourself with a letter or maybe even a phone call.If that doesn't work pay an attorney $400 to write a letter. 

Most check-ins/out should be close to automatic.With our 12 properties (9 ours and 3 cohosting) we get 1 phone call every 2-3 weeks.
