Just yesterday, I had to tell a tenant during a lease signing to flush the toilet in our office.  

Most of the one's that can't really afford it are flushed out early in the process.. either they go to the first pitch and then come to  a place like BP and get talked out of going further or just do the 3 day event and either think its not worth it or have the sense enough not to go further in debt.

You don't call Bank of NY when your door squeaks or your toilet won't flush, and your buyers won't either. 

So there was a continuous water flow vs one that leaks past the flush valve causing the toilet to run intermittently.

I had a similar situation with property damage, one of my tenants flushed a medicine bottle down one of their toilets and backed up the whole plumbing system. 

Unless you know a big cave man network of investors flush with cash I don’t understand logically how you could move something that’s not moving on the MLS.

Are they 1 rent increase from breaking their budget or are they flush with cash flow.

For toilets, I'd been using the 1.28 gpf type, but a fantastic .8 gallon per flush toilet is now on the market, it's called the Niagara Stealth, and it should be purchased at Home Depot(otherwise you're gonna pay like $50 or more to ship it somewhere.)

Keep your reserves flush, and limit exposure to short-term debt.If the worst does happen, none of this isn't going to matter anyway.

But if you're not sitting flush, I would be starting to look at your numbers a little more conservatively (i.e. how any potential buyer or lender would evaluate the same properties - which will be closer to 50% expense ratio) and probably setting aside a fair amount of that 'cashflow' for future expenses, and to be able to show liquidity, just in case you wanted to refinance, or go buy another property.
