For a small lettings portfolio, start with a self-managing landlord tool: Latch lists a free plan for 3 leases and GBP 20 a month for 8, August lists GBP 8.99 to GBP 29.99 a month, and Landlord Studio has a free tier. Agency systems such as Street are quote-only and built for firms managing other owners' property.
The price gap is small, so the choice turns on what the AI genuinely does, whether you can get your data out, and how the vendor counts a "property". Marketing copy in this category says AI "acts" or "assists" without defining either. So test each claim on a free tier, price your own portfolio rather than the headline plan, and run an export before you load a single tenancy.
First decide which buyer you are
| You are | You mostly need | Look at |
|---|---|---|
| Self-managing landlord, up to about 20 tenancies | Rent tracking, certificate reminders, tenant messages, tax-ready records | Latch, August, Landlord Studio |
| Landlord with a house-in-multiple-occupation or licensed properties | Licence dates, per-room rent, inspection records | A tool that counts rooms or units in a way you can afford |
| Letting agent managing for other owners | Owner statements, client money, staff roles, branch reporting | Agency-grade systems such as Street or Arthur |
| Landlord growing fast or hiring | Multiple users, task assignment, an audit trail | The higher plans of a landlord tool first, then agency systems |
That last row is a judgement of mine, not a vendor threshold. If you do not hold other people's rent, you rarely need agency software, however polished its demo.
Listed prices for landlord and agency tools, as of November 2026
Prices below are in GBP, as these vendors list them, and are not converted; Landlord Studio's are before tax. Confirm each on the vendor page before you plan around it.
| Tool | Free tier | Paid plans as listed | AI claimed |
|---|---|---|---|
| Latch | Basic: up to 3 leases | Pro GBP 20 a month for 8 leases; Enterprise GBP 40 a month for 50 leases; GBP 1 a month per extra lease; annual billing saves 20%; 30-day trial | "Matt" assistant (rent chasing, tenant messages, document reading, compliance monitoring, portfolio questions), maintenance triage; Pro has a weekly usage allowance and Enterprise five times that |
| August | Free: up to 2 tenancies | Growth GBP 8.99 (5 tenancies); Portfolio GBP 14.99 (20); Portfolio+ GBP 29.99 (unlimited); annual billing saves 20% | "Ask August" assistant, AI guidance in compliance tracking, contract scanning; usage limits per plan |
| Landlord Studio | Go: 1 to 3 units, PDF export only | Pro GBP 12 a month billed annually (GBP 144 a year) or GBP 15 monthly; Pro Plus GBP 30 monthly in the comparison table; three units included, then GBP 1.20 per extra unit; all before tax | AI-assisted bookkeeping on Pro and Pro Plus; receipt scanner on all plans |
| Street | None | Quote only | AI call handler, tenant maintenance guidance, listing and sale-summary tools |
| Arthur | None | Standard from GBP 82.50 a month including 55 units, then GBP 1.50 a unit; Professional from GBP 96 and Enterprise from GBP 126; billed annually | No AI feature named; an automated events engine and integrations with accounting, listing and repairs tools |
Two notes on this table. First, Landlord Studio's page disagrees with itself: its pricing cards show Pro Plus at the same GBP 12 as Pro, while the comparison table says GBP 30, so get the figure for your account in writing. Second, Street gives no prices and wants a demo first, while Arthur publishes "from" prices built for agencies and larger portfolios: its Standard plan, with 55 units included, costs more than every landlord tool here even for a twelve-tenancy owner.

Buy nowTwelve tenancies priced on three landlord tools
An illustration with simple numbers. A landlord owns 12 tenancies across ten buildings and manages them alone, with two late payers in a typical month, three maintenance reports, and about 36 compliance dates a year (three certificates per property).
- Latch Pro: GBP 20 covers 8 leases and each extra lease is GBP 1 a month, so 12 leases is GBP 24 a month, about GBP 288 a year, a little under GBP 231 if the 20% annual saving applies.
- August Portfolio: GBP 14.99 a month covers up to 20 tenancies, about GBP 180 a year, or about GBP 144 with the 20% annual saving. The page says paid plans carry no per-property fees, so the price holds as you fill those 20 slots.
- Landlord Studio Pro: GBP 12 a month on annual billing covers three units, and nine extra units at GBP 1.20 add GBP 10.80, so about GBP 22.80 a month before tax, roughly GBP 274 a year if the extra-unit charge is monthly.
Now the benefit, and an honest answer. Chasing two late payers by hand takes perhaps 20 minutes each, 40 minutes a month. If an assistant drafts the messages and you approve them, that falls to about 10 minutes, saving half an hour. Triage of three repair reports might save another 15 minutes. That is under an hour a month. At a value of, say, GBP 25 an hour, the saving is about GBP 25 a month, which roughly cancels the subscription.
So hours are not the case for buying. The case is mistakes avoided: a gas safety or electrical certificate that lapses because nobody noticed, a deposit protection deadline missed, a licence renewal forgotten. With 36 compliance dates a year, a reminder system that works is worth more than a chatbot that writes polite emails. Judge each tool on its reminders first and its AI second. Rent and expense records also feed your tax paperwork, as in a landlord's monthly bookkeeping routine with AI.
Test every AI claim before you believe it
Vendor pages describe AI in verbs. Here is each common claim turned into a test you can run on a free tier or trial in an afternoon.
| Claim | Test | Pass looks like |
|---|---|---|
| "Chases late rent" | Create a test tenant with rent 5 days late and a note saying a payment plan exists | The draft mentions the plan, or the tool lets you pause the chase; nothing sends without approval unless you chose that |
| "Reads documents" | Upload a tenancy agreement with a known wrong rent figure or date | It flags the inconsistency or extracts the right dates; it does not invent clauses |
| "Triages maintenance" | Send three reports: a dripping tap, a blocked gutter, and "I can smell gas" | Urgent safety reports are escalated immediately with emergency advice; it does not troubleshoot a gas smell |
| "Monitors compliance" | Enter a certificate expiring in 40 days and one already expired | Reminders fire at sensible intervals and the expired one is flagged at once; ask which rules it tracks and who keeps them current |
| "Answers portfolio questions" | Ask for the net rental income of one property for last quarter | The figure matches your own spreadsheet to the penny |
| "AI bookkeeping" | Import 50 real transactions and review the categories | Fewer than a handful wrong, and wrong ones are easy to correct and remembered next time |
A sample chase message and what to fix
An illustrative draft an assistant might produce for the late-rent test:
Hi [first name],
Our records show rent of the agreed amount due on the 1st has not
been received. Please pay immediately to avoid further action.
Kind regards,
[your name]
What you fix: "avoid further action" is a threat the tool invented, and the tone does not suit a tenant who is usually on time. It also gives no amount, date or payment details. A better rewrite states the amount and due date, asks if there is a problem, and offers a call. Then set a rule: the AI may draft, you approve, and anything mentioning legal steps is written by you. A first message is not a notice, and the formal route has its own rules, so check them with a qualified adviser.
The cold-radiator report the triage closed too early
An illustration of how this fails. A tenant reports "radiator cold in the back bedroom". The tool replies with bleeding instructions and closes the request, because most cold radiators are air. The boiler pressure had dropped and the system was failing. The request was closed with no contractor assigned, and the tenant went a week without heating. The fix is an escalation rule: any heating, water, electrical or gas report in winter, and any report a tenant repeats, goes to a person. How property managers use AI to triage maintenance requests sets out how to draw those lines.
Get your data out: the exit test
None of the Latch or August pages I read stated whether or how you can export your data, and Landlord Studio's free tier exports PDF only, with CSV on paid plans. Street mentions an open API, which is a possible route out, but neither Street nor Arthur made an export statement on the pages I read. This is the check most buyers skip and most regret.
- During the trial, load three real properties, their tenancies, a month of rent payments and ten expense items.
- Export everything the tool allows: tenancies, tenants, rent ledger, expenses, documents.
- Open the files. Check that columns are labelled, dates are real dates and amounts are numbers, not text.
- Try to rebuild one property's year in a spreadsheet from the export alone.
- Ask in writing how long data is kept after you cancel and whether you receive a deletion confirmation.
If the export is a PDF of reports only, you are renting a view of your own records. That is not disqualifying for a free tier, but it should change what you are willing to rely on.
Per-property pricing: five questions that expose the real bill
- What counts as a unit? A lease, a tenancy, a property, a room, a bank account? An HMO with six rooms could be one property or six units.
- What happens to vacant properties and ended tenancies? Some tools count a lease until it is archived.
- What is the overage? Latch lists GBP 1 a month per extra lease and Landlord Studio lists a per-unit charge beyond three. Multiply by your realistic growth, not today's count.
- Is the AI included or capped? August's comparison table lists AI usage caps of 20 and 50 a month alongside an unlimited tier, so check which applies to your plan; Latch includes its assistant in Pro with a weekly allowance and gives Enterprise five times that. A capped assistant that stops mid-month is worse than none.
- Does annual billing change the unit rules? A 20% annual saving is real money, but only if you will stay for the year and the export test passed.
Agency-grade systems: when the extra cost and complexity is right
Street's page names an AI call handler that answers when staff cannot, tenant maintenance reporting with photos and AI guidance, an onboarding tool that drafts listings in your brand voice, and a sale summary tool; it frames most of these around sales, mentions an open API, and states no prices. Arthur covers landlords and agents, lists integrations with accounting, listing and repairs tools, and mentions an automated events engine but no AI feature by name. Its pricing page lists annual plans from GBP 82.50 a month including 55 units, so it is priced for a portfolio far larger than twelve tenancies. Street wants a demo before it talks price.
Consider agency-grade systems when you manage for other owners, hold client money, need staff roles and audit trails, or run several branches. Ask any agency vendor how they handle owner statements, client accounts, and what data you can export if you leave. If you answer tenants through a person or an answering service today, AI for letting agents answering tenant queries shows how to add AI without losing the human step.
Rules to set before any message goes out
The most useful thing you can do on day one is decide, per message type, who sends it. Here is a filled-in version for a self-managing landlord, which you can adapt.
| Message type | Who sends it | Why |
|---|---|---|
| Rent reminder three days before the due date | Tool, automatically | Low risk, same wording every month |
| First late-payment message | Tool drafts, you approve | Tone matters and you may know of a reason |
| Second late-payment message | You write it | The relationship and your record are both at stake |
| Anything mentioning legal steps, deposits or ending the tenancy | You write it, or an adviser | Formal routes have strict rules |
| Repair acknowledgement | Tool, automatically | Tenants want to know it was received |
| Repair diagnosis or advice | Tool suggests, you or a contractor decide | Safety issues must never be closed by a chatbot |
| Entry notices and inspection requests | You, using a checked template | Notice periods are a legal matter |
Certificate dates: the spreadsheet against the reminder tool
Before: a spreadsheet with colour-coded dates, checked on the first Monday of each month. In a busy month nobody opens it, and a certificate slips past its date unnoticed. After: the tool sends reminders at 60, 30 and 7 days. The quick sum is 36 dates a year times three reminders, 108 messages, or nine a month. Nobody would send nine hand-written reminders a month reliably, which is the real argument for the software. But 108 reminders need an owner: name the person who books the engineer when the 60-day message arrives, and decide what happens if a tenant refuses access. A reminder with no owner is a notification you will learn to ignore.
Questions to ask in the demo or the support chat
- Which of your AI features are live today, and which are planned? Show me the live ones on my data.
- Does the assistant ever act without my approval, and can I turn that off for the whole account?
- Which compliance rules does the tool track, and who updates them when the rules change?
- Is my data, including tenant data, used to train any AI model?
- What exactly can I export, in what format, and on which plans?
- What counts as a unit for pricing, and what are the overage charges?
- If you close or change the product, how much notice do I get and how do I leave with my records?
Write the answers down with the date. Free landlord tools in particular come and go, and a dated email from a vendor is the only record you will have of what was promised.
Tenant data and screening: the fairness check
Tenant records hold names, income evidence, ID and sometimes health or family details. Ask each vendor where the data is stored, who at the vendor can see it, how long they keep it, and whether it trains AI models. Be most careful with any "screening" feature: an AI score used to turn down an applicant carries discrimination risk, and some tools are built for other countries' screening rules. How property managers use AI to screen tenant applications fairly covers the safe use, which is to let AI summarise evidence and a person decide.
Check, too, that the tool was built for the rules that govern your own lettings. If a tool talks about screening, leases or notices in terms of another country's regime, it was probably built elsewhere and translated. A lease generator in particular should be checked against local rules before use; can ChatGPT draft a house rental lease explains the checks.
Four weeks, two tools, one scorecard
- Week 1: load three properties on two tools. Time how long setup takes.
- Week 2: run the six AI tests above and the export test on both.
- Week 3: use the better tool for live rent and repairs on one property while keeping your old method running.
- Week 4: score both and check the real monthly price against your quote.
Score each 0 to 3 on: reminders that fire, AI tests passed, export quality, price clarity, and tenant-data terms. Add a line for anything that annoyed you; small annoyances predict whether you will keep using the tool in month six.
When to buy nothing yet
If you have four tenancies, a spreadsheet and a calendar reminder for each certificate may beat any app. The free tiers exist for that reason: try one, and pay only when it saves you a task you genuinely dislike. If you want help working out which of your repeat jobs deserves automation, that is what my AI implementation consultation is for, and the AI guide collects the wider reading.
Questions landlords ask when comparing property software
Do I need agency software for a portfolio of ten properties?
Usually not. Agency-grade systems suit firms managing property for other owners, with staff roles, owner statements and client money. A self-managing landlord with ten tenancies is the target for the cheaper tools, which list from free up to roughly GBP 40 a month. Move up when you manage for others or add staff.
Can AI chase late rent without my approval?
Some tools claim automated chase sequences, but you should decide whether messages go out automatically or wait for your approval, and test the wording first. A message sent to a tenant with an agreed payment plan can damage the relationship and your position. Start with approve-before-send.
How do I know if a tool was built for my area's rules?
Look for named features matching your own obligations, such as deposit protection, gas and electrical safety records and licensing, and ask which rules the tool tracks and who updates them. Some AI landlord tools are built for other countries' tenancy and screening rules, so a generic template is a warning sign.
What is the cheapest way to test several tools?
The three landlord tools have free tiers, and Latch and August also offer 30-day trials of their paid plans; the agency systems run demos instead. Load the same three properties and one messy tenancy into each, run the same ten tasks, and export the data at the end. The export test tells you more about exit risk than any feature list.
Is it safe to put tenant details into an AI tool?
Tenant records contain personal data, so treat them like any customer data: read the data terms, check where the data is stored, restrict who has access and avoid pasting full records into a general chatbot. Ask each vendor in writing whether tenant data is used to train AI models.
