It's a question of discrepancy.

Does this discrepancy seem right to you?

That being said, the frequency of discrepancies in the short period of time you've owned definitely seems very very high and I would probably lose a lot of confidence in the turnkey operator at that point.I'm casually looking into different turnkey markets but I do have a lot of reservations including the experiences you've had to endure. 

As evidence, many point to a large discrepancy between NOD’s and trustee sales.

Not everyone has the ability to weather such a discrepancy.  

However, I found a few discrepancies with information on my and some of my friends' houses.

I just found it odd that new people are still calling me in July from my previous campaign that began at the end of May.Is there a reasonable explanation on the discrepancy?

I haven't seen anyone else report a 0.4 to 0.5% response rate on a yellow letter mailer.The problem must be in one or more of these buckets:Mailer - I realize it is the same old yellow letter that everyone else uses, but there is just so many accounts of good response that I tend to think this is not the main issue.List - The owners I'm mailing to meet the suggested criteria with minor discrepancies that are not mathematically significant. 

I would ask to speak to their ins. agent.When you find a discrepancy during the option period you can then renegotiate the terms of the contract. 

Until the appraisal happens, we won't know if there's a discrepancy or not.
