How much more would it cost for your insurance to include coverage for tenants with pets?

I’m with Nationwide and they had my properties with only fire/dwelling coverage and nothing more.

you can demonstrate the debt service coverage ratio pretty easily. 

Tenants insurance coverage is very limited, essentially covering the tenant's personal property in the rental.

If your winning bid is more than that you will need to pay for additional coverage.

Perhaps the most comprehensive study was done by the Appraisal Institute and the Lawrence Berkeley National Laboratory (although it's a little bit dated now, having been most recently updated in 2015 I believe).

It is very easy to use and comprehensive. 

The coverage is called Loss Assessment and it is available as an endorsement to most condo unit owners or dwelling fire policies.

If you call on 2/1/21 and request is be cancelled back to 1/25/21 you would have gotten insurance from 1/25 to 2/1 already and the documentation just shows that it was not needed due to the sale or replacement of coverage.
