Most wholesalers who have 20 contracts at a time are spending a lot on marketing in order to secure so many deals.

The "word on the street" is that the owner may be looking to sell off market to an investor, and it is currently not listed on the MLS. 

Is the market too oversaturated?

You can analyze it all you want, but until you get it on the market, you don't know what the market will dictate.

Not only will it have a negative effect on landlords, I would imagine some owners of single family homes will choose to sell to an owner-buyer, thus reducing the number of rental properties on the market, making it more difficult for renters to find places to rent.

Off Market through a broker.

I am familiar with the market.

I was able to do it near a University (which it sounds like that's likely where you're moving to), and renting by the room can be a powerful strategy that not many are willing to do. 1) "Best" is subjective.

@Javian Moorman Plenty of CHA appliants out there...you just need to market to them on the open market like you would any rental and they will come. 

Study the market.
