If you are buying a new home in another country or state you should ask a home inspectors to check your property before you buy it.
There are many home inspectors all over the USA and you will easily find them on this website for Arizona home inspectors.
My friend was moving from Thailand to USA and he bought a house but before he did that he contacted Scottsdale home inspectors to make sure that his house had no problem. The home inspector found several cracks in the foundation and my friend deiced to take another house in the same area.
