The property you are looking at is actually a "sold" property, not a property currently for sale. It is a single-wide trailer, but it is not for sale. Trulia keeps all homes that have ever been listed on their site for comparisons. Please visit my site: paytonproperties.com and the properties you find on a property search there will most likely be currently for sale.
If you would like to get pre-qualified for a home mortgage, you can start that process at my site also, under "Quick Qualifier" button.
Have a great day!
