Slightly more scrutiny than bringing in piles of paper bills, depending on what kind of volume you are talking about and your bank.

If so, does anyone know the typical average volume of listings in New England at any particular time?

Sadly we have encountered this and worse - plumbing run on the cold side of an insulated wall - in properties we have purchased.The dripping faucet is the "common knowledge" with which we all grew-up, however in extreme cold you need a steady stream (dribble) of water to provide enough volume to slow the freeze, even then a prolonged bout of extreme cold (say a week between -40 & -10F) the pipes will eventually freeze through.

They live with windows open and no curtains - toddler is allowed to scream and sing song at mind boggling volume.

Steve, I was a Commissioner of a large Public Housing Authority, there are volumes of regulations and volumes concerning maintenance, more on HAP and Section 8.

A book with 500 volumes maybe.

I decided that the only explanation is the smaller guy bid and he hoped/gambled I just got one bid, and the winning bid had sunk costs in trucks and crew so it is more about getting every job they bid and making more on guaranteed volume vs fewer jobs but higher net per job. 

I think it is good business if you are a high-volume investor - it shows that you value your contractor's time.

I'm assuming volume will be low in the beginning so I have been looking at Specialty Answering Service for $31 a month plus $1.19 per minute.

Some big affiliate markers use 'Property Tracker' but our organization (MACK Companies) works in over 27 different neighborhoods with varying property taxes that make it unmanageable to use the 'general assumption' feature in Property Tracker at a volume as high as we do.
