A single family can be exchanged for a multi, office building, warehouse, raw land, even mineral rights.

For instance, if you are doing a fix-n-flip model, you would want to know what your raw profit and your annualized profit would be in both $s and %s if you borrowed X amount or if you simply paid cash. 

I have the raw data in excel and am pretty good with excel, so maybe that will speed it up a little. 

There is an oversupply of raw material here with nowhere to take it.  

I'm not judging anyone who disagrees with me, I just think it's a raw deal for a buyer and I'd like to offer them something different:I will only represent buyers (and will refer out if the house my buyer is interested in is listed by my brokerage) and I will charge a stated commission from my buyers, offset by any proceeds by the seller (which I will fully disclose).

There isn't much that you can do to improve the Condition of raw land (at least not economically) but you could consider laying out some money to do a building feasibility study, perf tests, well drilling, etc in order to make the lot more enticing to an end buyer.  

I have invested into a few raw land properties and sold them.

There have been no raw land sales in town in 7 years but new and existing homes have sold.

In raw terms, you need your $100,000 start up capital to grow to somewhere around $1.1 to 1.4 million in a decade, without risking it on crazy ideas or long-shot type investment that could possibly lose it all.My suggestion for that kind of growth would be high value add projects like purchasing distressed commercial real estate (multi-unit residential) in a high growth market with some cash partners, rehabbing and increasing rents substantially, then exiting within 2-3 years of stabilizing the project and moving on to the next.  

Sell commercial and buy raw land.
