Personally, I use the county auditor's site to gain the taxable value of the property, pull records on past sales history of the property through events like foreclosures, look at recent comps, and gain insight from a licensed realtor.

My personal home is listed on the county auditor's site - and on the MLS when I bought it - as a 4-bedroom.

Seller will be responsible for payment of: (i) its portion of taxes and assessments described in this Agreement; (ii) document preparation fees for the deed; (iii) document preparation fees and recording costs for all documents required to assume any applicable existing mortgages; (iv) all conveyance fees assessed by the County Auditor upon transfer of the deed; (v) all costs required to cure any title or survey defects; and (vii) any professional fees of attorneys or accountants providing services to Seller.B.

I would contact your local county auditor or treasurer for a list of tax delinquent properties.

I read somewhere on BP that no income but still deductions was a good auditor flag. 

There would be some risk that the auditors would not buy the argument.

Then when we sell, we are getting a commercial property auditor to evaluate the property and sell it as a business.

Somewhere on their web site I ran across guidelines for auditors looking at real estate investors.

Regarding property ownership, (and this applies to anyone looking to rent a home), don't hesitate to check your county's auditor website if you suspect the person you're dealing with doesn't own the property.

I am also interested in a property and am told by the "owner" on the auditor's website [which is US BANK TRUST NA (AS TRUSTEE FOR LSF9 MASTER PARTICIPATION TRUST)] that the account is owned by Caliber Home Loans.
