We've been to 2 or 3 and after 20 minutes we've left most of them because it has felt like a bunch of people trying to sell snake oil .

He also did the property record work, looking for older and out of town buyers, people most apt to want out...Don't want to steal the thunder from that book, but I like his scripts that he was able to turn into profitable owner financed deals....a good example of how you often have to make these types of deals happen, create them, rather than click an online link, or call a realtor...

We (at work) have had plenty of deals snaked, and a few come back to us, because we are upfront at the beginning.  

Why invest in their snake oil pitches. 

person got defensive and thought I was trying to snake the deal from them ..

i too looked into those (via https://www.sunsetranches.com). unless you can live without water, avoid like the plague... everyone else is.if there's some way to affordably bring water to that area, then it's a fantastic steal.you could catch some snakes, horney toads, desert hares and sell them as exotic pets.although the best use would be as a solar power farm.

The premium neighborhoods obviously demand higher rental rates - however, the cost to replace a roof or snake a sink in an A neighborhood is not going to be different than the cost in a non-premium neighborhood.

There are a lot of "snakes" out there.

Also, I don't want to steal @Don Konipol thunder but he is trying to give you a little bit of a reality check.  

You can snake it anywhere, it can expand and contract with cold without splitting (within reason).
