What is local here, and what is not

Baltimore is in IECC climate zone 4A. A typical year here has about 4,600 heating degree days and 1,150 cooling degree days, against 4,000 and 1,400 in the national reference. Local labor is 1.08 times a national crew, which is 8% higher. Planning electricity is 17.6¢ per kilowatt-hour, 0.8¢ above 16.8¢. BGE is the usual utility. Rates sit a little above the national planning figure.

Baltimore rowhouses are the typical stock: party walls, marble steps, and mechanical rooms that are really a corner of the basement. Labor is moderately above national. The high column is a flue shared the length of the block, or a panel recessed into a party wall that cannot take another breaker. Wellholt prices one house, not a group sale of a whole block of rentals.

Rent, sitting next to the repair on purpose

A one-bedroom planning rent is $1,450 a month. A two-bedroom is $1,750. These are not listings. They sit next to the repair prices so a low labor rate is not mistaken for an affordable city. On a $72,000 household income, that two-bedroom is about 29% of gross monthly income. Put your own income in the move calculator. If you rent, a window unit and a move are usually your decision. A water heater, an electrical panel, or a mini-split on the outside wall belongs to the owner. Use the range to read their quote.
