Mostly they are places looking for agents or law firms looking for paralegals.

The lower priced NPNs look like low hanging fruit but is that where a newbie should start?

This may work now and then but long term it is a lot of tail chasing and not a fruitful way to find deals.

Personally now that I do my own investments and close deals for commercial with my clients directly I have no use for agents.

The plaintiffs will go for the low-hanging fruit--the policy.  

However, if you search for agencies that provide work for travel nurses you can lock in a contract with them thus they guarantee the rent and are not rent sensitive as a travel nurse would be since they have a per diem that most will try to pocket as much of it as possible thus will look for a cheap but nice place to rent.Best of luck 

There are threads here that explain this, might do some searching and catch up with the basics.You really need to get a real estate book for agents, that will take you through the conventional side of real estate basics most here skip. 70% of the questions asked on BP are answered from a basic knowledge of RE.

For agent skills, The Millionaire Real Estate Agent by Gary Keller (and then The One Thing later) is nice.

If interested, I'm putting some details together for newer investors and for agents who want to serve investors / new agents in general, but definitely investor focused agent is the 'flavor'. 

My family who have been in RE for ages tell me the same thing.
