Our plumber does give us a description of the blockage or issue and we screen this for tenant responsibility- ie superman was snaked out of the toilet, cat litter was dumped out of the now unusable garbage disposal (also interesting in non pet friendly properties) and we will pass that charge on to the tenant with appropriate explanation. 

Many times the lender will require a letter of explanation to confirm its use/occupancy.

Thanks for the clear explanation Bill.

Care to message me with the explanation as well?

If it's something like 40 miles plus then the underwriter will probably ask for a letter of explanation to determine how it's realistic that you are going to live in the property and commute everyday. 

@Will Barnard good explanation.

Yes there are really only two possibilities given your explanation;1.

Shouldn't be too difficult, but will require an explanation.

@Sandeep Tyagi thanks for the explanation!

Plus a brief explanation of how to obtain them.
