There are a LOT of LLC's that aren't doing commercial.  A lot of people who buy rental properties as a business uses an LLC but the property is residential.  You should ALWAYS always confirm with a client that a property is commercial and that you should run it as such and automatically include your fee so they can approve it (or not).  Keep in mind that many times a client (mortgage company, bank, etc.) will order something without informing the vendor manager or abstractor that it's commercial.  Once THEY find out it's commercial, they cancel the order.

I have worked with Southern Land for years without a problem.  I'm sure if I look thru the hundreds of e-mails I could find an issue re payment, but we've always resolved it equitably, and I cannot remember the last time there was a problem.  But then I always make sure we're on the same page regarding price before I do the search especially when there almost a $200 difference between a residential order and a commercial order!  (This is why I don't have set prices for commercial...it's always best to confirm before going forward.)
