There are 2 electrical services, but only one gas and water meter.  

Neither of these is sub-metered for water or Electric or Gas. 1.

Guano removal in the chimney and atticThe fireplace has a gas insert, but the chimney stack is 94 years old (historic structure). 

Water filtration, gas pumps (no gas available for cars or food transportation) the Internet, lights, refrigeration would all be offline for months while the grid is brought back on.

Something to consider if the water heater is an older unit - a new gas/electric/propane instant on water heater isn't a bad idea.

Gas vs. electric (smooth top) range?

Here are some of the numbers:Purchase: $11,500Current monthly rent for unit 1: $500Current monthly rent for unit 2: $450Monthly average gas + electric: $137Monthly estimate for water + waste: $85Monthly insurance: $134Yearly taxes: $1700Total rehab estimate: $35,000 - $40,000Once the rehab is complete, I believe we will be able to raise the rent:Unit 1, converted into a 2 bed, 1 ½ bath: $625Unit 2: $525Our story starts with our desire for financial security in retirement.

Otherwise, you wouldn't be able to unlock any properties on a Supra lockbox, and you would have to depend on Zillow/Redfin for the newest listings (they are always behind).The most important thing you have to keep a record of will be gas/mileage (one or the either).

Oil barrel prices are starting to come back up and gas prices with it.

At first I thought sub-metering itself would be expensive (as with gas), but it looks like the water company is fine with me installing my own submeters and still using a single city meter for the building (http://www.bwsc.org/SERVICES/metering/submetering....).Based on submeter prices on Amazon, it looks like I may be able to have my plumber retrofit existing water connections and install low-flow everything for under $1000.
