Indexation with conditions
new_rent = base_rent × (current_health_index ÷ base_health_index)
On the lease anniversary, once per year. Some leases signed during the pandemic had statutory ceilings; we apply them when they apply.
Belgian rental law, your documents, one assistant.
VivaMyRent is the Belgian landlord platform with an AI assistant fluent in your own files and the rental law of Brussels, Flanders, and Wallonia. Built for landlords who want their property life under control, in plain Dutch or French.

The reality today
Three folders, two languages, eight unread emails from your tenant.
Belgian landlords manage their property the way they did in 2002. We watched ten of them do it. The pattern was the same every time.
Lost track of an indexation window
Re-typed the same tenant information
Googled a question about regional law
Lost a PEB certificate before renewal
Paid a lawyer for a question they later answered themselves
Self-reported, 10 Belgian landlords interviewed, October–November 2025. Small sample; shown here because every interviewee mentioned at least three of these.
Where are you on the journey?
The platform unfolds differently depending on how many keys you already hand out. Pick the one that fits today; we will be there for the next one too.
Invest
The first-time buyer
“I am thinking about buy-to-let. I have no property yet. I want to understand what I am getting into, not just be sold to.”
See the journey
Rent it out
The first-time landlord
“I just inherited my mother's flat. I want to rent it out properly, without spending a year on the legal mechanics.”
See the journey
Manage
The experienced landlord
“I already manage three properties. I want one place that does not surprise me, and an assistant that knows my files.”
See the journeyEvery answer shows its sources. If we cannot show one, we don't pretend to know.
The competition gives you another dashboard. We give you an assistant that knows the lease you uploaded, the date you signed it, and the article of the regional code that applies.
Every figure traces back to your own document or a cited legal source, dated and region-tagged. Every generated letter shows you the draft before it leaves your account. Nothing legal or financial is persisted without you confirming it. That is what grounded trust means.
Is the deposit return on time?
FlandersYes. Your tenant left on 15 January 2026. Under Flemish law you have up to two months from the inventory of fixtures to release the deposit. Today is day 34. You have 26 days left.
Inventory, 15 Jan 2026Vlaams Woninghuurdecreet, art. 37
Advisory; if your inventory contained reservations, the clock differs. Open the document for the full check.
Can I evict for repeated late payments?
WalloniaThis depends on context I do not have. To answer you properly I need the dates of the late payments, the amounts, and any reminders you sent. I can prepare the timeline for you if you upload the relevant payment receipts and your reminder letters.
This is a real product moment. Honest refusal beats a confident guess.
Three regions, three laws
One assistant that knows
which law applies to your property.
Belgian rental law is not Belgian. It is Flemish, Brussels, and Walloon, and they diverge on the questions you actually have. Indexation, energy, tenancy duration, deposit, evictions. The assistant tags every answer with the region it applies to.
Indexation tied to EPC
if EPC ≥ C: full indexation if EPC = D: partial (50%) if EPC = E or F: no indexation
Since 2022 the indexation is conditional on the energy performance rating. We check your last PEB and compute what you may legally apply.
Anniversary-locked
indexation allowed once per 12 months, on the anniversary of the lease, with notification to the tenant.
Like Brussels, with stricter notification timing. We draft the letter in French and remind you before the window closes.
Not promises. Defaults.
EU only
Hetzner data centres in Germany and Finland. Your documents never leave the European Union, and we will tell you when they move between EU regions.
NL · FR · DE
Every generated document, every legal answer, every email to your tenant in the language of the lease. German lands with the East Cantons of Wallonia.
Cite or refuse
An answer either traces back to your own document and a dated legal source, or the assistant tells you it does not know. There is no third option.
Pre-launch
Be first in your region.
We are opening the platform in Brussels and Flanders first, then Wallonia. Tell us where your property is and what kind of landlord you are; we will write to you in your language when your region opens.
