That sounds like a major pain in the... pipes!

But it can be a pain in the *** at the wrong timeI’ll hang up and listen.

I am not sure whoI could get the official answer from on whether I should file this tax or not. really a pain in the ***. 

Seems they would just block each other in therefore causing more of an issue.

Then on the other end of the spectrum I'd say are the little "corner stores" you find on blocks in the inner city with a little retail space on the ground floor and a couple units upstairs. 

During a septic inspection you would dig up a section of the drain field and see what is blocking it.

Make sure going forward all leases have a clause about requirement to maintain minimum temperature even if absent -- mine is 58 degrees and has a initial block next to it so they can't say they weren't aware of the term.

One thing I didn't see mentioned is making sure the number/dialer you're calling from is being marked as spam/spam likely or outright blocked by the carriers.

It's going to be very painful for all of us.

@Martin BrownAlso the reality is if you are trying to forecast numbers, the second you hit enter they are wrong as nothing goes the way you modeled it.The important thing to consider when modeling is to have data as accurate as possible (garbage in garbage out), but most importantly (and this is where investors miss the boat), what is the sensitivity to the numbersFor example if doing a flip with hard money, which causes more pain - $20k more to complete, 25k less in sales price or getting the right number but it takes 3 months longer?
