If no mortgage, worst case would be you can't get tenants in the house, it gets destroyed in a way insurance won't cover it (meth labs), you can't make the tax payments or whatever the case may be.

I am concerned that the buyer might not plan ahead well enough to make the annual tax payments.

For citizens, a Social Security number is typically used, while non-resident and resident aliens use an individual taxpayer identification number to remit taxes due.

I have gone to the property tax assessor's website and found the property tax bill, but it does not tell me any information on the property, just the tax payments and values. 

I'm not a tax expert, so I don't know if there is a tax advantage with the property tax payments where there is no mortgage.I'm sure I'm missing something here!

And then what happens is the longer it sits, the more risk there is for damage and the more likelihood there is that hud will have to discount it more.The govt should not be using these homes as some sort of social experiment when the taxpayer is the one footing the bill. 

And McDonalds and WalMart etc. continue to structure their wages and hours such that the taxpayers are subsidizing their employees so that they can make bigger profits for their shareholders.

And as far as I'm concerned that's the way it should be - you would be doing something illegal and are mooching off the rest of us taxpayers.

If someone is legally working in the US and doesn't have a SSN, they should have an ITIN (Individual Taxpayer Identification Number), which allows nonresident aliens to file a federal tax return.
