I've just recently added a coin-op washer and dryer to a 4 unit. 

Maybe I should become a coin-operated sooth sayer

I have seen government shut down, the crash of 2008, national speakers selling the next best shiny coin and so many other things that affected the real estate market and/or either aided or hurt real estate investors. 

I would opt for a coin-operated massaging bed first, then progress on to the lights for your next capital project. 

I regularly attend COIN, and also Tommy Harr's events.

So you never get your coins back if you only make minimums.

The flip side of that coin is that if you are in the market while rates are high, there's a lot less competition.

Weekly rent averages about $ 175 per week and I provide internet, utilities and a coin-op laundry. 

They have to present the offer whether they like it or not.On the other side of the coin, the Realtor is probably advising their client that seller financing incurs more risk to the seller.

This is what is coined "SPIN".
