What if they didn't pull a permit or have it inspected?

[Brian Knox]

In crawling the crawlspace of a $40-45k mill house (tiny, sort of subsistence standard of living), I noticed that whoever did the re-wire, most likely didn't do it to code or have it inspected.

I know that the current homeowner (who bought the house 10 yrs ago) didn't have an inspection or appraisal at the time he purchased. And I would probably try to avoid them as well (by using owner financing). So the current condition is sort of undocumented.

But what should I do about the electrical in order to have comfort that my tenants aren't in any imminent danger? Of course, I'd love a whole-home re-wire, but the $5-8k is a such a large percentage of the purchase price. And, as a landlord, do I have insurance or safety concerns I should be cognizant of?

I think the current homeowner/landlord is a little "fly by night." But I tend to overthink.

Thank you for any input you can offer!
