By doing a quick search I was able to find the following for AZ: "...If your lease is month-to-month, to terminate your lease, you or the landlord must give the other written notice at least thirty (30) days before the end of the last month you plan to live in the home..."

A few things you must figure out. 

The difference between doing it personally and inside of an IRA is the loan must be non-recourse. 

Bond for Deed must be French Law.. never heard that term in my 44 years of real estate.I am assuming its a debt instrument like a mortgage or deed of trust.Zero % financing is great.. as long as your not paying double what its really worth.with those terms it leads me to believe that the seller is tired of managing this and the management could be Hi touch lots of work.. so if you think your ready.. that s a pretty decent deal in my mind..

State laws vary state to state but title companies should be able to tell you what is required and if it must be handled by an attorney they can refer one.

Now, in order for me to get an FHA loan, it must be residential, and that would work if the building had 4 units.

Once lead is a known factor, it must be disclosed, no checking the box stating you have no knowledge of lead, so the seller and listing agent likely do not want the test performed.   

I've got cash reserves and I've begun looking for another house to buy as my primary.I must say I'm very excited but also a little bit nervous to take this next step.Thanks to BP for being a wealth of inspiration up to this point and in the future.I've already paid for a membership at ezlandlord forms and have those documents in order.

Proper notice for both landlord and tenant must be written and received by the other party at least ten days before the last day of the rental month.
