The claims history came with the address
Carriers consult a shared loss database that reports claims at the property, including those made by previous owners. A house with repeated water claims is quoted accordingly, and a new owner can find themselves paying for somebody else’s history without knowing it exists. You can request the report.
Unpermitted work is the common hidden problem
Distressed properties frequently carry alterations done without permits: a converted garage, added rooms, reworked electrical. That affects what a carrier will insure and what can be rebuilt after a loss, and it is not something a seller in that situation volunteers.
Expect an inspection and use it
Carriers typically inspect a newly acquired rental, and the findings are useful information about a building you do not yet know. Treating that report as a to-do list rather than an obstacle generally produces both better terms and a better property.
