You'll have to find ways to prove yourself as a real player because chances are they already have a rolodex of investors they go to. 

Who are the big players in the south side flipping and investing space?

@Dominic Rosato Exactly!

Make sure you have your key players, cleaner/ restock person they will make or break your businessMaintenance person, things will break and they will need to be available.Sounds like a great place and best of luck to ya.

Again speaking from experience in the market I operate in only, Roofstock isn't working with ANY of the biggest players in the Property Management space only the smaller operations who have a bigger need for another company to funnel them clients as they don't have a robust enough business to keep their pipelines full organically.

You can own Stocks with a top-tier brokerage, maybe JP Morgan or Vanguard, or even a newer player like M1 Finance.

You will want to avoid markets where a single industry dominates the local economy in the number of jobs since these kinds of markets a incredibly susceptible to swings in the market.Census Bureau: Building Permits Survey (BPS)The purpose of the Building Permits Survey (BPS) is to provide national, state, and local statistics on the number and valuation of new privately-owned housing units authorized by building permits in the United States.

Don't expect to steal stuff here though, as I mentioned these auctions are dominated by professionals that know what they are doing. 

If the sale is large enough you may have some national players come in. 

you got it about right.remember in the mid west its always been renter dominated ... and its always been slow to no growth in values.. very very long time for values to increase.. these homes are being sold for less than replacement costs. one of my First posts on BP that got about 150 hits.. was my assertion that 2% rule KILLS valuesyou should have been in on that one..
