Finance-first, HMRC-recognised

Hammock takes a deliberately narrow approach: finance-first, built around Open Banking rent matching and HMRC-recognised MTD filing, valued by self-managing landlords for its simplicity and low cost. Live bank feeds reconcile rent automatically, and it estimates your tax bill so you can set money aside through the year.

Two things make it stand out for particular landlords: per-property pricing keeps costs flat as tenant count grows, which is notably cost-effective for HMOs, and it supports limited companies and multiple ownership structures. The honest limitation from the same source: no compliance certificate tracking or tenancy management, so you’ll need a separate tool for those.

Management plus accounting

Landlord Vision is a UK-built platform with a deep reporting suite and full MTD support, handling tenancy management and compliance reminders alongside the books — the right pick if you want tenancy tracking, deposit handling, a maintenance log and document storage bundled with MTD-compliant accounting.

The trade-off against Hammock is clear: heavier on the operational side, lighter on bookkeeping niceties. If your pain is managing tenancies and certificates as much as filing tax, this is the more complete answer.

Mobile-first with a free tier

Landlord Studio suits smaller self-managing portfolios wanting a capable mobile app, with a free tier and gentle paid plans — and it’s on the HMRC-recognised list, which is the qualifying test.

For a landlord with one to three properties who does admin from a phone between other commitments, this is the least friction available. Free up to three units, then around £7.99 per month. Latch is another option with a free tier and AI features worth comparing.

Mainstream accounting at scale

Once a portfolio gets large, or where property sits alongside other business activity, Xero or QuickBooks Online become the practical default — both for MTD compliance and for deeper accounting: multi-bank reconciliation, advanced reporting and accountant collaboration.

Xero with a property add-on works well when you also have non-property income. The trade-off is that you lose the per-property profitability view that landlord-specific tools give you out of the box, so you’re configuring rather than being handed it.

Large portfolios & HMOs

Arthur Online sits at the top end of the market, built for larger portfolios and letting agents needing customisable workflows and separate portals — depth that comes with a higher price and a steeper learning curve.

But read the callout above before buying: Arthur Online does not offer MTD compliance. At £48/month or more, that means pairing it with a separate MTD-recognised tool if you’re in scope — a real cost and a real reason to check your requirements before committing.

Certificates & possession readiness

The Renters’ Rights Act shifted what matters: the job the Act moved to the centre is evidencing compliance and possession readiness — certificate tracking with expiry alerts and a record of what was served when. A landlord with one property faces the same route and the same council powers as one with fifty.

Good software tracks every certificate against every property, reminding you at 90, 60 and 30 days before expiry, and stores the documents themselves so you can produce them on demand. Some platforms include this; dedicated compliance tools exist to layer on top if yours doesn’t. A spreadsheet can’t remind you of a renewal or produce anything a council or court would treat as a reliable record.

Legislation & long documents

Claude is the tool for the reading a modern landlord can’t avoid: the Renters’ Rights Act guidance, a selective licensing scheme’s conditions, a leasehold agreement, a management company’s terms, an insurance policy, or a council improvement notice.

It’s genuinely good at turning a long statutory document into a plain-English summary of what applies to you. It is not a substitute for advice — possession, deposit and licensing errors are expensive and procedurally strict, so use it to understand before you speak to a solicitor or your landlord association, not instead of.

Tenant communication

ChatGPT handles the writing: property listings, tenant welcome letters, rent increase notices worded reasonably, contractor briefs, the response to a repair request, and the difficult conversation about arrears or damage.

Tone matters more here than most landlords credit. A repair or arrears message that reads as aggressive tends to escalate; a calm, clear one resolves. Having a measured draft to edit — rather than writing while irritated — is worth more than it sounds. Never rely on it for notice periods or prescribed wording.

Calls & inspections

Otter.ai transcribes and summarises with action points — useful for contractor discussions, agent calls, and dictating inspection notes as you walk a property rather than writing them up later from memory.

The walk-and-talk use is the good one: describe condition room by room, and you have a dated written record to sit alongside your photographs. Tell people when you’re recording a conversation, and be mindful that anything involving tenants carries data-protection obligations.

Listings & tenant handbooks

Canva produces the tenant handbook that prevents half your calls — how the boiler works, bin days, who to contact for what, what’s the tenant’s responsibility versus yours — plus listing graphics, floor plan layouts and inventory report templates.

A good handbook is the cheapest tenant-relations investment available. Most avoidable maintenance calls are about something a tenant simply didn’t know, and a well-made document handed over at check-in reduces both friction and disputes.
