Running Comps in Low Income Areas

[Mario Castelan]

Hey guys,
As the title says, I'm interested in how you would go about running comps in low income areas. I want to start brrrring properties in my "backyard" Camden, NJ, but I'm having a difficult time finding good comps. If you don't know, Camden is a low income area, and most homes don't sell here. However, there is money to be made as in good cash flow. I want to use hard money to purchase, and rehab the properties, and then refinance them. But I'm having a difficult time running numbers.
Any thoughts, suggestions, or help would be greatly appreciated!
