Idk though, maybe i am just stressing a little to much for my age (which is 20), and also please excuse my raw uncut use of grammar, felt like the only way to relate to you all would be to explain as best i could, where i am coming from.

Multi family would be the easiest to do in commercial, besides raw land I suppose, but big bucks always means more due diligence.A buyer probably doesn't need a Realtor in a larger multi.

Find a small house in a nice area and scape it and build a big house and make big bucks.Find raw land and subdivide and sell is another way.A house on a large lot.

A developer is a broad term.I have developed raw land in which I purchased at a great price, then hired engineers to re-plat (divide up the parcel into multiple parcels, add in infrastructure (roads, utilities, drainage, etc) and then sold for a profit.I also have and am buying single lots, and then building on them, then selling for profit.These are just two of many examples as a "developer".

And I don't know if OUR bid had much of a chance of making money after the rehab.Had another house we looked at that got 35 other offers.40% of the offers coming in are all cash investors in the DFW market.I just feel like the low hanging fruit in the DFW area may be gone, especially for out of state investors, Its getting really tough to find anything that works right now in terms of cash flow. 

Compare that property to the one you already have and see which one would be more fruitful. 

Wholesaling raw land can be difficult.

And charting days on market per price range (not available but raw data is) is where one can see where market limits lie.  

So I just got into escrow for a parcel of raw land, and I'm financing the purchase via a Private Money Lender (friend, colleague).

If you do everything right and things don't work out, that's bad luck, but over time it'll bear way more fruit than someone who does bad work, gets lucky, and considers that a path to success.
