I am a recent graduate of Villanova University and currently work as an auditor.

Some auditors may be worse than others.Depending upon your AGI, you may not have tax due anyway if you are in the 15% tax bracket.

And along with receipts, most auditors like proof of payment such as a bank statement or cancelled check.

Very marginal Tenants here: sometimes they have eviction or two and put extra security deposits, always pay late fees and once in a while there is an eviction happen.These you can tell by higher crime rate, subsidized school lunches very high, low market value and high %% of rentals (auditor site gives that info as "non owner occupied".The best idea to get a feeling for the areas you'd be comfortable to buy- drive by on Friday evening or Saturday  whole day long.Statistics are good but without personal look you might get mistaken - there are plenty good pockets in bad neighborhoods and vise versa 

I pull all my info from the county auditors website.

So, are there disclosure issues when the house is listed...could you say study/bedroom...and I guess it could never be formally recorded at the auditors level as being a "bedroom"...

Lastly, you can get the market rent by asking real estate agents who specialize in leasing in that area.Vacancy - use 10% as a starting point but in strong rental markets, assume 5%.RE Taxes - you can get this info through the county auditor or county treasurer's office/websites.Insurance - call an insurance broker.

Funder did doc checks then it went to attorney and finally to CPA ( who was the best at catching things she used to be a forensic auditor) Mistakes are made in these deals I find when your using attorney for closings you must review the docs  much more thoroughly than a west coast title and escrow company not sure why but that was and is my experience.  

In such cases, what is done here, folks call the RE Commission, they have local auditors in the area.

I just got one for a rehab project on a vacant house that has been sitting for around 4 years. 1 year policy was about $600.A field auditor came by and took photos while I was working there one day.
