But toys that I have spent money on are  pinball machines,  a classic car,  etc.  

Being a "well-oiled" machine did not happen overnight (and believe me - there are things I want to improve).The important thing is to take action on a daily basis.Co-opetition works indeed.By the way, I used to live in Mason Ohio actually.

You can even see it happening today: McDonald CEO stated that machines will eventually replace fast food workers.

Rent can be modeled using machine learning based on comps, location, and local economic factors.

tenants will flush drano and liquid plumber and take years off that septics life, is their washer machines at the property?  

Anyone have experience with owning an ice machine?

Watching my house be built was an art as they had all the subs doing what they needed building batches of 5-6 houses like a well oiled machine.

See when you rent out SFH's, you usually can only charge rent.But for multi's, you can create additional income streams, like adding a laundry room, charging for covered parking, installing vending machines, storage, etc.You might know this, but the value of a multi is determined by the NOI (net operating income).

those machines cost about 30k an hour to operate or so..
