This property has in the past been pasture for grazing, and we built a rental on one of the lots, in addition to planting trees and running irrigation. 

Homeowner's, Landlords, Builder's Risk, Renter's Policies, Blanket Liability Policies, a bit about Auto Policies because trees fall on someone's car, Professional Liability if you're consulting, Lender's Liability if you're lending (and if you're not consulting or lending, understanding these helps protect you as a consumer, knowing you're covered if they really screw up).  

MTR's are not my cup of tea, in the slightest, but coining and use of the term and differences in the business model- it's happening.

Unless the property is inside city limitis, you will probably have to do an environmental study before you can get building permits.In many areas, you can't cut down old growth trees, so look into that and also be sure there is enough room to build without taking out big trees.I would make any offers on bare land contingent upon being able to get building permits.

Ex #1: I needed 2 trees cut in the backyard.

Paying off the debt first is a classic case of either:1 - not seeing the forest for the trees.2 - Really, REALLY, bad math3 - a combination of #'s 1 and 2

You will need to get a local, rockstar Realtor, contractor, lender, and property manager.https://www.biggerpockets.com/blog/core-four-real-estate-tea...I invest locally in Columbus, Ohio

At one house, a tree fell down due to a random wind storm and another day at the cleaner was late/delayed and wasn't responding to my texts.

Believe it or not, I have been past the Ohio River and the last time I was in California, I didn't see money growning on trees.
