Insight needed on making the numbers make sense!!!

[Account Closed]

I am working on a wholesale deal with someone who has a buyer that has $5000 to put down for a house and wants to pay $400-$500 a month for it. It is my job to find the home.  I've found a house for sale by an owner who wants $60,000. The mortgage is not free and clear. No repairs have to be done to the house. Will this house work with the numbers the buyer wants to work with? 

I know this may be a dumb newbie question but I am very new to this and just want to hear what people with more experience had to say. Thanks!
