From reading all the posts, it looks like Android users are by far the largest segment of the members! 

It's something that crossed my mind before but I think getting familiar with Brandon's story through the podcast and first couple chapters of the book has helped me see that A) as a strategy forming well defined partnerships using separate entities is a great way to segment our business and B) I don't need a AAAA business rating to legitimately be investable-just a successful track record (we've almost doubled money in 6 months already) a straightforward workable plan and high caliber deals.

(those are opinions) Wherever you invest, here's a partial list of what I think should be considered:The local markets where they are considering investing (Supply and Demand, Vacancy rate etc.)Economy of the local areas (Broad based economy, Unemployment rate, Median Household Income, etc.)the types of properties in any given area (SFR, MFR, Condos, Mobile homes, Mixed Use, General Office, Medical Office, Retail, Parking lots, Marinas,  etc.)Investors may also want to look at properties such as Vacation Rentals (Which is a growing segment of the market in certain areas, and can in fact cash flow very well) though they require much more managementOther segments of the market that can cash flow very well are group type housing (sober living, transitional housing for the homeless, and other types of housing) that rent bed space and can be very lucrative.

Beyond that everyone has their different niche and segment. 

We're planning on yellow letters (handwritten for now; likely transitioning to printing our own printed faux-handwritten letters in the future), and are trying to figure out what segment to market to and where to get our list.  

In addition, speculative construction loans to a residential builder are often associated with homes that are not presold, and thus pose a greater potential risk than construction loans to individuals on their personal residences....The composition of the nonperforming asset portfolio is dominated by the commercial construction and land development segment which represents 44.5% of the total nonperforming assets and individually this segment represents 35.0% of the nonaccrual loan portfolio and 74.9% of the foreclosed assets portfolio.

Here's a few that have worked well for us:1) Make sure you have found a GREAT market segment to mail.

The problem with an "S" or "C" corporation owning a property is that when it comes time to sell, the selling of that property counts for income tax purposes against the corporation as a whole, there is no segmenting of the income and expenses of an asset as is allowed within an LLC structure.

Study copywriting, list segmentation, direct response marketing and one-on-one sales techniques. 

There is segment called "Don't Be a Little B**ch".
