Sounds like a good idea in land constrained coastal California.

This book got me off the sidelines and in the game: Build a Rental Property Empire by Mark Ferguson and this book elevated my landlording methods: Managing Rental Properties by Heather & Brandon Turner~ Lindsey

Often 10-20-30 degrees cooler than the inland Valley's the OR Coast is a remote but accessible refuge. 

Have been looking around and found that the Inland Empire have had properties that could make cash flow work.

Empires normally crash after 250 years. 

Stack up as much cash as you can while growing your empire. 

@Jay Hinrichs agreed and I asked their person who trains Kurt and I believe in the main discussion what exactly should I be double checking for - one would imagine they’ve seen things come up in land.

Hi Nina.If I were not experienced in land lording and property manager, I would look personally to the extent you want to learn or experience property management versus hiring someone else that you trust to do the job.Yes, the cost for a property manager is important but not essential- the cost between property managers are not double or triple the cost of others (say like attorneys in some areas of law or cars). 

Others have built rental empires.

I have yet to see a free course be anything worthwhile but there are some that are relatively cheap for what they give you.I personally am a mid 6 figure earner & have been in land for 8 years now.I have numerous course, including Bosch's.
