I am trying to figure out how the numbers work for the Housing Authority. 

Make sure to get all of this upfront so you know exactly what you have to factor into your numbers.As far as documents, they usually have a folder worth of documents to fill out depending on the lender you go with, anything from credit authorization forms, to business and LLC disclosures, rehab estimates, rehab draw/fee disclosures and all the closing documents of course.The bottom line is to get all the numbers/fees/terms up front so you can plug and chug the numbers to see if it will work out!

State has authorized, but I think in most places it will just cause trouble. 

Also, make sure that you get a limited power of attorney from the seller so that you will have authorization to deal directly with the lender.

I would recommend contacting the man's caseworker to get clarity from the Housing Authority on what will happen and what they recommend.If it turns out the husband's not coming back, then at least you know the facts and can make the best decision possible for you. 

A while ago I read the BP book on managing rental properties and the author mentioned the 1% and 2% rule as being solid measures for evaluating a deal.  

You should get advice from your lawyer on these legal matters as I am not legally qualified or authorized to give legal advice. 

I did some research and learned the city/county must have a local Public Housing Authority which can administer the voucher. 

The author is David M.

It should be far and away the easiest kind of landlording to do, something anybody should be able to, at the most, read two or three books about and handle.A small, local portfolio should be the second-easiest sort of landlording to do, especially if you buy some quality and stay far away from C-, D-class areas and tenants with poor credit.But the unavoidable truth for me has become that most people who want to buy property as an investment aren't good at being a landlord in a position of both authority and responsibility.
