A garden unit is leased from the gangway steps down
The unit below the sidewalk line is the hardest door on your rent roll, and the video that fills it is the one your owners will study too.
Basements are close to universal here, and in a two-flat or a greystone the lowest unit is a garden apartment with its own entrance off the gangway. It rents for less than the unit above it, it takes longer to fill, and the owner is usually the last person willing to say why.
Film it the way an applicant walks it. Down the gangway steps, through the door, past the light well, into the back room where the ceiling comes down. An honest walkthrough loses you the applicants who were going to cancel at the showing anyway.
Say what the footage cannot. Which way the windows face, how far below grade the floor sits, where the ceiling drops under a beam, whether the unit has heat of its own or shares a boiler with the building. Those questions get asked at every single showing.
Owners watch that video for a different reason. Somebody in Andersonville whose garden unit sat empty from March to July is watching to see whether anybody has finally worked out how to lease one, and that is the whole argument for hiring you.
