The QI world is unregulated and it’s important to make sure the company you choose is insured and bonded and has the experience and expertise to assist you.  

I've called my insurance company but wanted to confirm if the seller had any responsibility to disclose the flooding basement issues that could not have been discovered during the inspection.

Expense are quite low: $2000 year taxes, $600 insurance, $700 street lights, $3000 vacancy/lost rent, $1000 upgrading UTL & gravel/pavement per year = $7,300/year expenses.

I’ve never run into an insurance company who’s inspection would turn up a specific panel.
