90% is pretty high.

@CraigIf you have two offers with that high of down payment already you must be living right!

I ended up closing on a duplex house this week with the intent to rehab the whole place.

I would protect myself and cut my losses so I was not looking over my shoulder or getting high blood pressure every time I heard a knock on the door (hoping it is not the FBI showing up to ask you some questions). 

Still ended up being great due to the location.

A platform that updates their data daily or weekly is covering a staggering cost in order to provide that to the end user.

Is the property under a high tension power line or down wind from the horse rendering factory or on a main thoroughfare or some other obstruction that you wouldn't want to live near?

There was a news reporter at the sale and they interviewed the high bidder, who admitted that they had not seen the property, but were certain that they would be building their family home there. 

Could you end up finding one or even multiple deals at auction?
