I am Jezwah Harris. I am a nurse practitioner and a lawyer. I founded Veritas because I spent too many years watching renters get burned by online ESA services that sold them a piece of paper, took their money, and disappeared the moment a landlord pushed back. The pattern is so consistent that I want to write it down in one place, plainly, so you can spot it before you spend the $29 or $59 or $89 that is about to be wasted.
This is not a competitor hit piece. I am not naming names. I am describing behaviors. If a service shows several of these patterns, walk away.
What a "letter mill" actually is
A letter mill is a website that issues ESA documentation in volume, with little or no real clinical evaluation, often for a flat fee that is well below the cost of a legitimate evaluation. The business model is volume: the more letters issued per hour, the more money the operation makes. The product is the same letter, with a different name on top.
The clinician who signs the letters (if a real clinician signs them at all) often has a license in only one or two states but issues letters to residents of all 50. The "evaluation" is frequently a 60-second checkbox quiz with no actual conversation. Some services do not employ licensed clinicians at all and use signatures that are forged or recycled.
Landlords have caught on. Tenant attorneys have caught on. State licensing boards have caught on. Several states now have specific statutes targeting fraudulent ESA letters and the services that issue them. California's AB 468 (2021) is the most prominent example -- it requires a 30-day clinician relationship before an ESA letter is issued, prohibits issuing the letter as the result of a one-time online questionnaire, and requires the clinician to be licensed in California. Other states have followed.
The bottom line: a letter from a mill is increasingly likely to get rejected by a landlord, scrutinized by a state regulator, or, in some states, exposed as legally invalid. You paid $29 for a piece of paper that does not work.
The seven warning signs
Here is the checklist I would give to a friend before they paid for an online ESA letter.
1. The price is below $80 (and almost certainly below $50)
A real licensed clinician spends 30 to 60 minutes on a real evaluation. Even at modest hourly rates, the actual cost of that clinician's time is in the $80 to $200 range. Practices that charge under that range either are not paying a clinician at all, are paying a clinician for so little time that the evaluation is not real, or are subsidizing the price by selling something else (data, upsells, "registry fees"). If the price looks too good to be true, it almost certainly is.
Veritas charges $99. That is on the low end of what a real evaluation costs, made possible by telehealth efficiency and a focused single-service practice. We are not the cheapest. We are not trying to be.
2. The site promises a guaranteed outcome
Watch for phrases like:
- "Approved in 24 hours"
- "Guaranteed letter"
- "Get your ESA letter or your money back"
- "Approval rate: 99.7 percent"
A real clinician cannot guarantee an outcome before they have evaluated you. A clinician who promises an outcome before the evaluation is not really evaluating anyone -- they are running a sales funnel where the "evaluation" is a formality. State licensing boards consider outcome guarantees in clinical care to be a violation of professional ethics.
A money-back-if-not-approved guarantee is the same red flag, restated. It directly incentivizes the clinician to approve everyone, because the only way to avoid refunds is to never decline. That incentive structure is the opposite of clinical judgment.
Veritas does not promise outcomes. We promise an honest evaluation. The fee is for the clinician's time and judgment, regardless of whether they decide a letter is appropriate.
3. There is no real video or phone evaluation
A real evaluation involves a real conversation. That can be a video call, a phone call, or in-person, but there has to be a clinician on the other end actually talking to you. If the entire process is "fill out a form and we will email you the letter," there is no clinician evaluating anything. The form is theater.
Watch for sites that describe their process as:
- "Take our online assessment"
- "Answer a few questions and we will match you with a clinician"
- "No appointment needed"
- "100 percent online process" (with no scheduling step)
Compare to a real evaluation flow: you submit an intake form, you pay, you complete a clinical questionnaire, you schedule a video appointment with a specific clinician, you have the appointment, the clinician reviews and decides. That is more steps, on purpose, because the steps correspond to the things a clinician actually has to do.
4. The clinician is not licensed in your state
Federal law defers to state licensure. A clinician licensed only in Florida cannot legally write an ESA letter for a patient who lives in Texas. Many letter mills route everyone through a single clinician in a single state, then sell letters nationwide. Those letters are not legally valid in the patient's home state, and increasingly, landlords know to check.
Before you pay, the site should clearly state which states their clinicians are licensed in. If they say "we serve all 50 states" but only list one or two clinicians, the math does not work -- you cannot have one clinician licensed in all 50 states. You can verify any U.S. clinician's license status through the relevant state licensing board (or just through the state's own NP/PA/MD/PsyD board website).
Veritas clinicians are credentialed in 17 states. We do not serve states outside of that list. If you live in a state we do not serve, we will tell you so on the intake form -- and we will not take your money.
5. The site sells "registration" or "ID cards"
There is no federal ESA registry. There is no national database. There is no required ID card. Any service that offers to "register your ESA" or "issue an ESA ID card" for an extra fee is selling air. The card has no legal weight. The registration appears in no government database. The transaction is pure profit margin on nothing.
This is one of the strongest signals of a mill. A legitimate clinical practice does not need to upsell you on fake credentials. The letter alone is what landlords ask for. Anything beyond that is a tell that the operation is selling marketing materials, not health care.
We cover this in detail in Why ESA Registries Are a Scam (And What Actually Counts).
6. There is no clinician name on the letter (or the name is hidden)
A real ESA letter includes the clinician's full name, license type, license number, and state of licensure. That information is necessary because the landlord may need to verify it. A letter that says "issued by our medical team" or signs with a generic title and no license number is not verifiable -- and the landlord will know.
Mills sometimes hide the clinician identity because the same clinician's name appears on thousands of letters issued in states where they are not licensed. Hiding the name protects the operation. It does not protect you.
7. The site has been around for less than a year (or has no real address)
Letter mills come and go. They get reported, they shut down, they reopen under a new domain. A site that was registered six months ago, has no physical mailing address, no listed clinicians, no state-licensure disclosure, and no way to actually contact a real person is a site that may not exist next month -- and you may have no recourse if the letter does not work.
Look for: a real corporate entity (LLC, PC, etc.), a real mailing address, a real clinician roster, a real way to contact the practice. Veritas is Veritas Behavioral Group, LLC, organized in Wyoming, with a mailing address in North Miami, Florida, and a public clinician roster.
What a real evaluation costs and looks like
A real evaluation in 2026 typically costs between $80 and $250 depending on the practice and the state. The mid-point is around $125. Veritas charges $99 because we are a focused, telehealth-only, single-service practice -- the structure lets us keep the fee modest without cutting corners on the evaluation itself.
The flow looks like this:
- Intake. You complete a basic identification and address form.
- Payment. You pay the $99 evaluation fee through a secure payment processor (Stripe).
- Clinical questionnaire. You complete validated screening tools (GAD-7, PHQ-9, plus a structured history) before your appointment.
- Appointment. You meet with a licensed nurse practitioner via secure video for a clinical conversation, typically 30 to 45 minutes.
- Clinical decision. The clinician reviews your information and either issues a letter, declines and explains why, or asks for additional information.
- Delivery. If a letter is issued, you receive a signed PDF on the clinician's letterhead, usually within 24 to 48 hours of the appointment.
That is a real evaluation. It costs more than $29 because it takes more than 90 seconds.
What to do if you already paid for a fake letter
If you have already paid for an online ESA letter and you are now wondering if it is real, here is the practical guide:
- Check the letter for clinician name, license type, license number, and state. If any of those are missing, the letter is unlikely to be valid.
- Verify the license. Look up the clinician on the state licensing board's website. If the license is in a different state from yours, the letter is not valid for your housing.
- Check the date. If the letter is older than 12 months, most landlords will ask for a fresh one anyway.
- Check the issuing service. Search for reviews, check the Better Business Bureau, look for complaints filed with the state attorney general. Letter mills often have a public trail.
- If the letter is fake or invalid, the next step is a real evaluation. Yes, that means paying again. The frustrating reality is that you got something for $29 that was not a real letter, and a real letter requires a real evaluation. We will be honest with you about whether one is appropriate.

The honest pitch
I am not going to pretend I am a neutral observer. I run a competing service. The reason we charge $99 instead of $29, employ NPs licensed in each of the 17 states we serve, and decline to issue letters when the clinical picture does not support one is that this is the only model that holds up to landlord scrutiny in 2026. If you want a letter that gets accepted, you need a real evaluation by a real clinician licensed in your state. There are several practices that meet that bar. We are one of them.
The thing I want to leave you with is not "use Veritas" -- it is "do not use a letter mill." If you find another reputable practice that does the same kind of clinical work we do, that is fine. Just please do not give your money to a service that is going to send you a generic PDF that fails the moment your landlord looks at it.
Talk to a Veritas clinician
A licensed nurse practitioner in your state will evaluate whether ESA documentation is clinically appropriate in your situation. The fee is $99 and covers the evaluation itself, not a guaranteed outcome. If the clinician decides a letter is not the right fit, they will tell you why -- that honest answer is part of what you are paying for.
