Check out Cardone’s 10X Rule for more on ambitious goal setting.I would start by defining how much I wanted to make and then working backwards.

In a residential lease, would not the type of tenancy typically be defined by legislation?   

You can also agree (both parties, of course) that under certain circumstances (which you define) you can have an extension of so many days.  

If your goal is monthly steady income you buy rentals, if your goal is to increase your annual income and you do not care if it is steady flipping and wholesaling may be the areas you want to focus.Once you have defined the first two parts of the strategy you need to look at your market and figure out which market needs you can fill with your desired strategy.

Many things define success.....If your property is appreciating in value and your tenants are paying down most of the mortgage or all of it, that puts you in a great position. 

When it comes to properties that are defined as residential, I would either pay all cash or search for properties owned by an owner that will consider Seller Financing. 

I've paid myself a mgt fee through my S-corp to fund my defined benefit retirement plan.  

The security of a job and defined income, is like a addiction that Needs to be brokenI'm free!!!!!! 

Define abandoned?

@Michael Wentzel, define a pile of cash.
