What Jay said is accurate. 

Hello @Alicia England - You will if it is a good deal or if the numbers will work by gathering the market data where the property is located.Start by going to a site such as zillow.com or realtor.com and look at what similar properties have recently sold for.

The auction I attended this month had two properties that were still on the list when I left my house but were pulled by the time the auction started.2) You are bidding but always out bidYou need to evaluate how you are determining you max bida) right comps for ARVb) accurate repair estimatesc) ROI expectationsIn other words how are you pricing the deal. 

I've asked around to some friends who live in areas with homes valued around $100k so I do have a few areas in mind, but any help on how to gather more info and what else I should add to my list would be greatly appreciated.  

Yes, there's a lot of variation in that area, you would need to provide the block number or the actual address to receive an accurate "valuation". 

They also have some forecasting data(estimates) for next 5 or 10 years, and they seems to be accurate at least for our investment areas!
