@RLM , as per your post:
- "Whose responsibility to fix skirting on a TOH?"
For a TOH it is the Tenant's Responsibility to repair the skirting (as it is part of their home).
Now your post did state:
- "The Tenant contends the septic guy damaged it when he was performing some work recently and wants us to pay for the repair of the skirting."
Did you hire the Septic Contractor or did the previous Owner (as you stated you were a new MHP Owner)?
If you hired the Septic Contractor, personally as the Owner I would pay for the repair.
However, if the previous Owner had hired the Septic Contractor, personally as the Owner I could go either way.
If you pay, the Tenants might think that you are easy or soft and try to get away with stuff.
However, if it was your Septic Contractor, it is really the Septic Contractor's fault...which means your fault and you get to pay :-).
We wish you the very best!
