I like to think of each marketing technique as a line in the water, and constantly be looking for ways to get more lines in the water because it all adds up.  

SFR with Metro Water Services are $20-40 per month (bigger houses than this I realize), but I would think it might be more for 14 units than what is shown there.  

According to MA General Laws, there is a section about submetering water/sewer but it does not address natural gas.

I agree but the big sharks move in first and it filters down to the little guy You have to have the expertise and vision to sniff out those neighborhoods that might change early An example was downtown Vegas 5 years ago The ceo of Zappos started buying on Fremont street  years ago and investors quickly moved in when they got wind of it Today is a desirable area with upscale tenants Your expertise is to sniff out these events early and take advantage It is not something t  laugh at but to capitalize on thru farming your area 

I have the following:- Clean Gutters - yearly- AC maintenance - yearly- AC filters - every 6 months- Gas furnace filters - yearly

Every ceiling tile and sheatrock has water damage.  

I just found out today that her water bill is at $1,098.66.

The following is a partial list of things that wear out or become outdated over time and eventually need to be replaced for every property:-Roof-Siding-Hot water tank-Furnace-A/C system-Electrical system-Plumbing system (inside)-Sewer service line-Water service line-Any concrete exposed to the elements (sidewalks/porches)-WindowsIf you calculate the cost of replacing each of those items and divide them by the expected useful life, then sum that up, you'll come up with a monthly amount that you can expect to spend on capex over the long term.

The most important parts of this business strategy are 1) Buying rent-ready homes in areas that will continuously filter in high quality tenants with little to no vacancy rate, 2) Having exceptional performance from property manager and, 3) Each home meet the standards set in place for purchaseIf anyone out there is interested in becoming a mentor and collegue of mine I'd reall appreciate it.

And I would tell them exactly what you are looking for and not beat around the bush.When they set up an email alert for you on the MLS, they can set it up to filter listings however you want.
