What precisely defines those criteria is based on individual facts and circumstances, as indicated by the courts and IRS.  

@Frank SanchezBut isn't that basically the exact same situation that I described because you are allocating a portion of your portfolio to a low risk/low reward investment vehicle and repositioning when equity prices are cheap?

If you own any of your vehicles outright, take out a loan on them.2.

This is like asking someone if they liked a movie, unfortunately, two people can walk away with a totally different outcome and view point.. the info at Dave's bootcamp is enough to get someone going and to make offers on up to 200 units and understand what they are doing the whole time, which is really all you need, there are many places, like bigger pockets to get all the information needed to accomplish this same goal, but like following a recipe in a cook book, what is better, the cook book with all the info you need to follow, or the chef standing there next to you making sure you use the exact precise ingredients? 

I had to take out a small auto loan to purchase a vehicle.

This is precisely the type of thing that gets overlooked when investors only look at cash flow and ignore equity from forced appreciation.

Make them understand their stupidity in not having insurance now comes at a price.In the future make sure that any tenant intending to park a vehicle on your property must have it registered, plated and fully insured.

They will run the vehicle tag/vin and issue an order of compliance and maybe even have it towed for you.  

@Frank Chin I had the opportunity to travel to NY a few years ago with my son and his middle school.I hear that just owning a car, in many parts, costs thousands of $$ just for parking.The last car we purchased was our fourth vehicle. 

I actually need a pickup truck, so I have been looking into how tax advantage of purchasing a vehicle for business purposes.
