I've been chipping away for 4 years with no luck.

@Esra KanisicakGo to IREM.org search for ARM certified property managers they handle the smaller properties.Deputize the neighbor to keep an eye on things with $50 worth of wood chips for them.Stock up on aspirin if you do it yourself from a distance.Good luckPaul

Can anyone recommend architects and appraisers in the area, other than those involved in the 12 Oaks project?

Matt Bill Gulley's advice above is great, try to spend this next year until your 18 slowly chipping at those suggestions to be prepared for getting involved once you legally can.Also maybe start your "plan" a few months before you turn 18.

You want more control, take the chips off and go find another deal to create greater cash flow and equity for yourself.

Digital guidebook, welcome basket with water bottles and chips, instant oatmeal, etc. and any other little things you can think to add around as well! 

Every time I buy tax liens in Sedona or Village of Oak Creek they redeem fairly quickly.  

Can anyone recommend an Arborist who can cut down an 80 foot Oak Tree?

I'm in Sherman Oaks too.

I am able to leverage myself into several positive equity positions where, for the same amount of cash using traditional methods, I would have been able to acquire less than one third the number of properties or amount of equity.Cash flow and equity positions are, in my mind, very similar to tech stocks and strong dividend producing blue chip stocks.
