Close the sale and ask for the order. 

It is for sale by owner, but my realtor told me that the owner has an existing wrap loan on it.

it shouldn't be hard to search online for records of the property posted as a short term rental-search the address.

I just looked online at the BS&A site for Belleville to look at the property.

The reason you are seeing a wide range per foot of sale price is because there are hundreds of variables in NNN properties.

Specifically, you'll want to collect and analyze a LOT of comp sales data (including data pertaining to days on market, price reductions, the buyer pool, etc.) so that you have a very good understanding of the buyer pool, and how difficult it could be to sell this type of property...I'd suggest talking with multiple agents who have experience with this type of property, and asking them what type of DOM, ARV, and sale experience they would predict for the property.Before you take on $25k+ of credit card debt for a rehab, you'll want to consider all the potential problems you might face with your strategy, and potential solutions to those problems.

There is government data online to see where good schools are, low crime rates, and desirable city amenities.  

Would be interested to hear your experience. online/offline. 

Adam Hey Adam, In Wholesaling, you are acting as a principal (buyer) in the transaction so you would just need a regular purchase & sale agreement with "and/or assigns" language and a marketing clause for you to be able to promote the property while you are under contract.
