How to keep a rental waitlist for units that will open soon

Why bother with a list

Every vacant day costs rent. Inquiries that arrive when nothing is available usually vanish. A short list turns them into a head start: when you give notice of a unit that will be free next month, you can write to people who already asked, before you spend anything on ads. See how to cut days vacant.

What to collect, and what to leave out

• Name, email and, if they agree to texts, a phone number.
• The number of bedrooms they want and the month they hope to move.
• The date they signed up.

Leave out anything that is not needed to contact them and match a unit. Never ask about family make-up, religion, national origin, disability or any other protected trait (see HUD's overview). Keep the list somewhere private, and delete entries when people say they have found a home or ask you to.

Write the rules before the first name

A fair list is one where the order and the process are decided in advance and applied to everyone. Fair housing law treats like applicants alike, and a list that follows a clear, dated rule shows that you did (see 42 U.S.C. 3604). Decide:

1. The order: first come, first served by sign-up date is the simplest.
2. What happens when a unit opens: you contact the first person who matches the bedrooms and the date, and give them a set time, such as 48 hours, to say yes.
3. What happens if they pass or do not reply: you move to the next person, and note it.
4. What a spot costs: nothing. Do not charge a fee to join a list. Check your state before you collect any money to hold a unit, because rules differ.
5. Your screening rule. Being on the list does not approve anyone. Each person still goes through the same written criteria.

Example a made-up owner has 11 names for 1 and 2 bedrooms. A 2 bedroom opens in 45 days. The owner writes to the first 2 bedroom name with the date, the rent and the application link, and gives 48 hours to reply. That person passes, so the owner writes to the second name, who applies the same day.

How to message the list

Send one short note, individually or by blind copy: what is available, from when, the rent, how to apply and until when the offer holds. Include a way to leave the list. For email, the sender and unsubscribe rules in the FTC's CAN-SPAM guide may apply to promotional mail, and texts need the person's consent, so keep to messages about the unit they asked about. If you are unsure, ask your own advisor.

How DoorKeeping handles it

DoorKeeping does not keep a waitlist for you today. A spreadsheet with a date column does the job. What it does give you for each vacant or soon-vacant unit is a prefilled listing: the unit on notice shows as available the day after its lease ends, so you can publish it the moment you are ready, and a showing request form and an Apply button are on the page. Publishing is an approval you accept yourself. See the connect page for the listing tools in Claude or ChatGPT.

Questions

Should a landlord keep a rental waitlist?

It can shorten vacancies, if the list has written rules and everyone on it is treated the same way.

In what order should I contact people on a waitlist?

First come, first served by sign-up date is the simplest and easiest to defend, as long as you apply it to everyone.

Can I charge a fee to join a waitlist?

Do not. Check your state before collecting any money to hold a unit, because rules on holding deposits and fees vary.

Does being on the list mean approval?

No. Everyone still goes through the same written screening criteria.
