I tell my clients to always head to the auditors website and punch in the sale price to the tax section and see what the taxes would be.

I did what I felt was thorough due diligence on it, and observed that despite selling for 100k in 2000, 115k in 2005 and 125k in 2017 the county auditor has regularly been valuing the property between 70-80k for over 20 years.

find the property address, search the address on the local auditor site to get the owner (or search the LLC on opencorporates.com if it is an LLC to get the owner ), search the name on fastpeoplesearch.com and call the phone numbers associated with that name and location/address.

Details are not for this post.The methods I'm talking about involve convincing your IRS auditor that your numbers were honest and reliable by using other evidence, less convincing than receipts.

So I just sat with a friend who spent his career (decades) as a commercial bank loan officer, mostly in real estate, with a retirement career as an independent bank auditor.

You can start by pulling lists from your county auditor's website.

Call your county auditor and see.

@Masashi Borges-Silva if you have an address for one you can go on the Franklin County Auditors and find the other addresses.

Why would any company hire Internal Auditors when they have there own accounting specialists working on and creating financial statements in the company they work for themselves?

Contact people who are "Property insurance auditors"   Those who do valuations for properties that have "fire damage, natural disaster, roof damage etc..."
