Buying below market price

[Lindsey Bengue]

What suggestions do you guys have if a REI gets a contract with the homeowner for 20% the market price? The house does not need any repairs or updates, its pretty much ready to go. It is not listed on the mls, Its worth about 950000 but he would consider a 850,000. I will be looking at the property Tomorrow and want to know what to be prepared for and what things to tackle when renegotiating my deal to a better price. Should I partner with a realtor on this one?

What do you guys think? Thank you Bigger Pockets for a good source of real estate education!!
