In the automotive segment,  cars and trucks are becoming much more expensive each day.

They can suggest segments with motivation where your letter or postcard can stand out.

@Nguyen QuachFrom Wikipedia: https://en.wikipedia.org/wiki/Merced_station_(California_High-Speed_Rail)"The California High-Speed Rail Authority's February 2016 draft business plan said that the Merced station would not begin service at the same time as the initial San Jose to Bakersfield route in 2025, but would likely open in 2029 instead.[4] The Merced City Council vigorously opposed the delay in the station opening, noting that Merced would be a prime area for commuters seeking to use high-speed rail to access jobs in Silicon Valley.[5] In response, the April 2016 revisions to the business plan indeed included Merced in the initial construction segment, initially as a single-track spur connecting only to the westbound track to the Bay Area, with buildout of the full Chowchilla Wye happening later.[6][7]"If you want to buy in Merced for a single track rail that just came in WAAAAY overbudget (35%) in the hopes that Merced won't be cut from the list in order to come in on budget, and that economy will still be in a good place 7 years from now when the station finally opens (if it isn't cut), then be my guest. 

And, much, much more.The whole three day event was broken up into one or two hour segments with 10 minutes of each segment dedicated to hard core house flipping information, and it was good information, very accurate and to the point, and I truly believe this, absolutely no sarcasm in that statement.

also you will need find your niche and focus on creating value in a deal within that segment of RE.  

I was listening to NPR because they had a segment about rent costs and real estate. 

I'm sure that there are Assisted Living Management companies that you can use in other States that you can talk with if your considering capitalizing on the explosive growth of the Senior population and this segment of Real Estate Development in your area.Bill Bradfield

Guess what landlords, this is the fastest growing segment, baby-boomers are now retired and getting up there, I'm at the tail end of them, barely.

But the general principal of breaking down the different segments of your real estate.

But some investors do make money flipping in lower end neighborhoods in LA but it's really a market segment i am not familiar with.
