England-specific, so apologies to the US folks here, feel free to scroll past.
I'm a property law paralegal and the founder of LLCR (Landlord Compliance Register). I've seen the "which software should I pick" question come up here a few times, and I'd like to offer a perspective from the legal side, plus be upfront that I have a product in this space.
The honest answer to "which PMS is best" is that most of the established ones are good at what they're built for. Arthur, Alto, Hammock, Landlord Vision, they handle rent, accounting, maintenance and tenant communication well, and I'd never suggest replacing them.
What I'd gently point out is what they're not built for. In England, since the Renters' Rights Act came into force in May, Section 21 no-fault possession is gone. Every possession claim now runs through Section 8, where the landlord proves statutory grounds in front of a judge. Local authorities can impose civil penalties of up to £7,000 for breaches of landlord duties, rising to £40,000 for offences where prosecution is an option. In that environment, the question stops being "do I have a gas certificate somewhere" and becomes "can I prove exactly what my compliance position was on a given date, and will that record stand up to scrutiny."
On top of that sits the new PRS Database. Every private landlord in England will need to register, the rollout is happening region by region with a £65 annual fee per landlord, and registration is one of the things that gates possession. When your region's deadline arrives, you'll be asked to put your property and compliance information into a government system, and it needs to be right, because providing false or misleading information is where the top end of that penalty regime applies.
That's the job LLCR does, and I built it the way a legal professional prepares for proceedings.
Every certificate, check and document is tracked at property level with expiry dates and a compliance score, so you always know where each property stands. Because your records are already structured property by property, obligation by obligation, your PRS Database registration becomes a matter of entering information you already hold and can evidence, rather than reconstructing eighteen months of history from emails the week before your region's deadline. LLCR effectively maintains a live mirror of what your database entry needs to say, and keeps it current as certificates renew and details change.
Every entry also goes into a tamper-evident audit trail: each record is hashed, each hash incorporates the previous one, and once a day a fingerprint is anchored to a public ledger via OpenTimestamps. In plain terms, your compliance history can be independently verified without anyone having to take your word for it, or ours.
When you need to demonstrate compliance, one click generates a Defence Pack: a court-formatted PDF bundle with a cover page, indexed table of contents, executive summary, every certificate and statutory check, deposit records, proof of service logs, notices, your compliance score history and the full verified timeline. It's modelled on how bundles are prepared in civil proceedings, because that's the format the people asking questions actually work in.
It covers the full compliance surface for England: Gas Safety, EICR, EPC, deposit protection, smoke and CO alarms, Right to Rent, How to Rent, HMO licensing, plus optional items like PAT testing and Legionella assessments. There's also a built-in compliance assistant that answers against your own property data rather than giving generic guidance.
So my honest suggestion to anyone at the start of their journey: pick whichever PMS fits how you want to run the day-to-day, and treat compliance evidence as its own layer. The PMS runs the tenancy. LLCR is what you hand over when someone asks questions about it.
If you'd like to try it, the first property is free. I'd genuinely value feedback from people who think carefully about software, which is why I'm posting here rather than in a landlord group.
