AI for leasing inquiries: faster answers, the same for everyone

An AI leasing assistant is safe when it answers only from your written policies, gives every prospect the same answer, treats assistance animals as not pets and sends every exception to a person.

Zillow inquiry, 9:48 p.m.hi is the 2 bed on Indian School still available? I have an ESA, hes a lab mix about 70 lbs. is that ok

One reply

Yes, the 2-bedroom is still available. Our pet policy allows up to two pets under 40 lbs, with a $400 pet deposit and $35 a month pet rent, so unfortunately a 70 lb dog wouldn't qualify. Let me know if you have any other questions.

Polite, accurate to the pet policy, and the start of a fair housing complaint.
The other

Yes, the 2-bedroom is still available. An emotional support animal isn't a pet under our policy, so the weight limit, pet deposit and pet rent don't apply. I've passed this to our leasing team, and someone will follow up today about the next step. Would you like to book a showing in the meantime?

Handed to a person, with the conversation attached.
Both replies come from an assistant reading the same pet policy. The first one did exactly what it was told. This guide is about telling it the rest.

The first reply isn't a malfunction. The assistant was handed the pet policy and applied it, weight limit and fees included, to an animal the policy doesn't cover. The difference between the two replies is what it was told to hand off. An AI leasing assistant will answer at two in the afternoon and two in the morning, to every prospect who writes in, in exactly the words it was given. That cuts both ways, and this guide is about making it cut the right way.

Why AI can help here

A busy leasing team answers forty inquiries in forty slightly different ways. One agent mentions the concession, another doesn't. One prospect hears back in ten minutes, another waits two days because their email landed on a Friday afternoon. None of it is malicious, and all of it is inconsistency. Inconsistency is where fair housing risk hides, because two prospects treated differently is the whole complaint.

An assistant that answers from your written policies gives every prospect the same answer, in the same words, in minutes. On that one dimension it isn't a lesser version of a leasing agent. It's a more consistent one.

Four more conversations

Text, Saturday 8:15 a.m.do you take section 8? I have a voucher for a 2 bedroom

RiskySorry, we don't participate in the Section 8 program at this property.

SafeYes, we accept housing vouchers. Here are our written screening criteria and the application link, and I can book you a showing this week.

Since 2023, Phoenix's fair housing code counts rental assistance as a protected source of income inside city limits; neighboring cities have their own rules. A “no Section 8” line left over from an old listing is exactly what an assistant repeats faithfully.

Apartments.com inquiry, Tuesday 6:02 p.m.We're a family of 5 (3 kids). Is the 2 bed big enough or should we look at your 3 beds? How are the schools there?

RiskyFive might be a tight fit in the 2-bedroom. You might like our Camelback building better: it's a family-friendly community near top-rated schools.

SafeOur written occupancy limit for the 2-bedroom is five people, so your household fits, and the 3-bedrooms are listed here too. The school district's site shows school boundaries. Want to see either unit?

The assistant copied that line from the Camelback building's marketing page. Suggesting a building because it's “family-friendly” is steering by familial status, and vouching for schools is how steering usually sounds. Occupancy is answered from the written limit, the same for every household.

Website chat, Thursday 2:40 p.m.The place down the street is doing 6 weeks free. Can you match that or knock something off the deposit?

RiskyI can offer $200 off the deposit if you sign a lease this week.

SafeThe current special on this unit is in the listing. Matching another offer or changing a deposit is a decision for our leasing team, so I've passed your question on, and someone will get back to you today.

Someone set the tool up to offer up to $200 off to close a lease. An assistant that negotiates will offer one prospect a deal it never offers the next. Concessions are a person's decision, applied the same way to everyone.

Zillow inquiry, Sunday 11:20 a.m.I use a wheelchair. Is there a step at the front door of the unit? Would you be able to put in a ramp?

RiskyThere's one step at the entry. Unfortunately, we aren't able to make modifications to the building.

SafeThere's one step at the entry. A ramp is a request for a reasonable modification, so I've passed it to our team, and someone will follow up with you directly today.

The first half of the risky reply is fine. The second half answers a modification request with a policy, and that decision belongs to a person.

Do this

  • Answer only from what's written: the listing, the pet policy, the fees, the screening criteria, the occupancy limit. If it isn't written down, the assistant says a person will follow up, and a person does.
  • Read the old listings before the assistant does. A “no Section 8” line from a few years ago now breaks Phoenix's fair housing code for units inside city limits, and the assistant will repeat it as faithfully as everything else. Have your attorney check how your income rule applies to a voucher holder's share of the rent, too.
  • Send everyone the same criteria and the same application link.
  • Treat assistance animals as not pets, and send those requests, and any accessibility request, to a person. They're accommodation or modification requests with legal weight, and an assistance animal doesn't pay a pet deposit, pet fee or pet rent (HUD notice FHEO-2020-01, January 2020).
  • Book showings, and answer availability, pricing and move-in dates from the listing.
  • Log every conversation, so you can show what was said to whom.
  • Before it talks to a prospect, run the four conversations above past it, and your own hardest ones. If it gets one wrong, fix the policy or the instructions, not the reply.

Not that

  • Don't ask about, or comment on, protected characteristics. Federally that's race, color, religion, sex, familial status, national origin and disability. Arizona covers the same groups (A.R.S. 41-1491.14, 41-1491.19), and Phoenix adds sexual orientation, gender identity or expression and source of income (City Code ch. 18). The assistant can ask how many people will live in the unit if your occupancy policy needs that. It never asks whether any of them are children.
  • Don't steer. Not toward a unit, a building, a floor or a neighborhood, and not with a friendly aside about who lives there.
  • Don't make exceptions. Waived deposits, held units and concessions are decisions for a person, applied the same way to everyone.
  • Don't screen. Approve-or-deny is made by your team, against your written criteria.

The federal Fair Housing Act applies to what an assistant says exactly as it applies to your staff. Nothing on this page is legal advice.

Who answers what

The assistant answersfrom the written policy, word for word

  • “is the 2 bed still available”
  • “how much is the pet deposit”
  • “can I see it Saturday morning”
  • “what do I need to qualify”
  • “do you take vouchers”

A person answerswith the conversation attached

  • “I have an ESA, is that ok”
  • “can you hold it till the 1st”
  • “is it a safe area”
  • “can you do a month free”
  • “I need a ground floor unit, I have a disability”
The left column has one written answer per question, vouchers included. Everything on the right has a decision or a judgment in it. Even a person shouldn't describe a neighborhood as safe or not: they point to the city's public crime map and let the prospect judge.

Notice the shape. The assistant takes the questions that have one written answer. A person takes everything with a decision in it. That's the same line I'd draw in any automation, but here the line is also where the legal exposure sits, so it's worth drawing in pen.

The written policy is the product

Everything above depends on one thing: what you've written down. The assistant can only be as consistent and as careful as your listing, your pet and assistance-animal policy and your screening criteria. If those documents are vague, the assistant will be vague in the same places, to every prospect, in writing.

So before you set one up, have your attorney read those documents. They're what it will repeat, word for word, to every person who asks. That's also the good news. Fixing one policy fixes every conversation at once, which is more than you can say for a leasing team on a busy Saturday.

Common questions

Is it legal to use AI to answer leasing inquiries?
It can be, if it follows the same fair housing rules as your staff. It should answer only from your written policies, give everyone the same information, never ask about protected characteristics and send exceptions to a person.
What should an AI leasing assistant never do?
Ask about or comment on protected characteristics, steer prospects toward or away from units, answer accommodation requests on its own, or make screening decisions. Those go to a person every time.
Who handles assistance animal requests?
A person. Requests about assistance animals or accessibility changes are accommodation requests with legal weight, so the assistant should recognize them and pass them to your team with the conversation attached.
Can a leasing assistant turn away Section 8 in Phoenix?
No, not for units inside Phoenix city limits. Since 2023, Phoenix's fair housing code protects source of income, including rental assistance. Check old listings for “no Section 8” lines before an assistant repeats them.
