Having the ladder pull away from the house can be a good thing in some cases as the ladders shown used synthetics to carry the load so if the floor below you is on fire the windows can break and enough heat escape to start to melt the ladder as you are climbing down. The other important thing is have a way to get up to the window and turn around to climb out. The standard night stand would break under an adults weight and in a fire you need to be fast to get out as you are right in the smokes path as you opened a window and the vents are now sending smoke into the room even if you keep the door closed. A folding step stool or even a sturdy chair can give you the step up you need and something to hold onto as you find the first rung of the ladder.
