As we know stuff happens, if things change and can't assure that appropriate value-add at entry, it takes some exceptional integrity to tell those throwing $ at one "sorry, it's a no-go at the moment, we simply don't have viable enough deals to enter at this market timing" and risk they get imbedded with others. 

Throw it away and get a normal fridge.  

Throw in some washers and dryers in the units—it's a game-changer.

On paper, it looked brilliant..cheap money, quick turnaround, and a profit projection that made his eyes light up.It taught me that the real risk isn’t just the cost of capital, it’s the predictabilty of your exit strategy.

Cashing out $400k and throwing it in an index fund is a viable option as well.

aim for a good house, not a cheap house as it will attract lower quality tenants and cost you more in the long run.

It might seem like a kindness to provide a printer to a traveling professional, but until they invent one that works on every device, every time; that doesn't need paper at two in the morning; and has cheap toner that refills itself, we will pass on that amenity.I am sure there are other examples for all 4 quadrants, but like @Allen Duan wrote the important thing is to look at amentities through the lens of the end user (with an eye towards the "competition").

One posted about buying a cheap quad,  i used her bumbers provided and my maintenance/cap ex to show negative $600/month.  

I'm cheap. 

Years ago we didn't require it and just recommended it to the tenant, but it's so cheap and gives our insurer something/someone to abrogate against should we have to make a claim that we don't allow it to be optional anymore.
