You can definitely find rehab homes by working with an agent specifically in the areas you are looking. Most of these homes may be bank owned and/or short sales so owner financing may be impossible. I suggest you give Peter a call and he can get you started.

The worst of these are sold for little more than the value of the land but there are plenty available that can be saved. Mind you these are mostly in the inner city.
If you are interested send me your email address and I will send you samples.
In recent months I have been looking in Paterson, Prospect Park and Haledon for several customers for suitable properties.
