I advised the public housing authority in Broken Arrow, OK.

You want to find out how far away any potential tax auction might be as that could be another avenue.Simply tell the seller that X is the most you can pay for the property but you are willing to negotiate with the bank on his behalf (requires his authorization to be submitted to the bank) to get them to agree to accept less.  

Call the local Housing Authority and get a copy of their utility allowance so you know how much to deduct from the above for utilities to compute what kind of room you have to raise rents (without utils.) 

The person signing the contract has to have the legal authority to sell the property.  

Our local water authority is making life a bit difficult and is delaying getting a final payout number.  

'Never Eat Alone' (not sure of author) This business is all about networking!

The local housing authority will do an initial inspection once you sign a lease with a voucher holder and then yearly inspections after but they are mostly safety issues they are looking for.

The housing authority won't pay it.

I would offer the family member a preferred rate of return on their money and give them no rights or decision making authority in the deal.

This was a suggestion from the book Landlording on Auto Pilot which I do recommend (I am not the author but it has a fair amount of useful tips :=).Thanks for your service to the country and good luck.
