did half the flip work, sold with new walls and new electric/plumbing.

Anything that involves a load bearing wall will generally need an architect IME, but it can also be required (maybe indirectly) through the jurisdiction's building code/enforcement.Got it, thank you for lending your expertise!

Windows would be my next check-point (less than R1) and then wall insulation: I would not be surprised if they have no insulation inside, but you can do blow-in, which only requires a small hole.A home looses heat in two ways: heat conduction (which you can slow down with insulation) and drafts, which in old houses is usually the biggest culprit.

During demo, if they open up a wall and find a leak that requires a change order. the change order should be specific to that repair and have a cost associated with it. 6.

-If you have ceiling heights for 48" wall cabinets, that's great.

Offering a smart TV with streaming services, USB chargers by the beds, and premium bathroom toiletries are also great touches that guests love.

Hey @Marc Shin, you definitely need more art on the walls and color.

Walls are priced one way, ceilings another, then you have baseboard, trim and doors. 

Electric: is the easiest to split, but may require holes cut in walls to separate the units.Gas: gas lines aren't as flexible as wires, but it can usually be done affordably.Water: most cities will NOT install additional water meters on a property.

The units are very utilitarian, in the first listing there are only 2 art pieces in the living room, they are too small for the wall, and they look like they were ordered off of amazon which isn't necessarily bad but it also doesn't stand out.
