Everything that goes into managing a rental.
Rent & bills

Reporting
What each rental earns and what it's worth — returns after costs, estimated value, and rent vs. similar places nearby.
Contracts
The whole lifecycle — from the first lease through annual adjustments, renewal, and move-out.
Maintenance
From request and photos to the back-and-forth, looping in a pro, and resolution — all on record.
Messages
Questions, agreements, and disputes stay with the rental.
Everything in one place
Payments, bills, documents, and conversations — all easy to find.
How Mabenn keeps everything updated
Add your rental
Your property, tenant, contract, rent, and key dates.
Connect what you want tracked
A bank connection confirms payments; bill sources bring bills in automatically.
Invite the tenant
They get their own view, and you both see the same rental record.
Mabenn keeps the record updated
Rent confirmed as it's paid, bills as they're issued, contract dates before they matter — without manual entry.
When you connect a bank account, Mabenn uses read-only access only to confirm rent and bill payments. It never moves money, and your transactions are never shared with other users or third parties.
01
Rent & bills
Mabenn watches every payment land — rent in your account, utilities paid, condo boletos clearing. All confirmed automatically.
New bills find their way in too. Boletos appear the day they're issued. For utilities, each property gets its own Mabenn email — your providers send the bills there, no inbox digging.
You don't enter anything. Your tenant doesn't either. Mabenn does it all.
02
Contracts
Mabenn keeps the contract running end to end — you don't track dates or draft documents from scratch.
- 01
First lease
Draft the contract with a new tenant and sign it with a legally valid ICP-Brasil digital signature, all in one place.
- 02
Annual adjustment
On schedule, Mabenn calculates the contract's IPCA adjustment and notifies your tenant of the new rent.
- 03
Renewal
Both sides see the renewal window early, with time to talk it through.
- 04
Notices & move-out
Late rent, or a contract ending? Mabenn drafts the notices the Lei do Inquilinato requires — and the paperwork a lawyer would otherwise prepare if it escalates.
Ask Mabenn.
The AI assistant knows the Lei do Inquilinato and your specific contract. Landlord and tenant can both ask, and both see the same answer.
For complex disputes, a lawyer is still the right call.
03
Messages & maintenance
Every conversation about the rental lives in Mabenn, next to the rental it's about — timestamped, and never lost in WhatsApp or email.
- 01
Maintenance
From the request and photos, through the back-and-forth and looping in an outside pro, to resolution — the whole thread on record.
- 02
Questions & agreements
Everyday questions and what you settled on, kept next to the rental.
- 03
Disputes
A contested charge, a withheld deposit, damage at move-out — raise it with the proof attached.
04
Reporting
See how each rental is really doing — what it earns, what it costs, what it's worth, and where it's leaving money on the table.
- 01
Revenue
What each rental earns — rent collected by month, year, and lifetime.
- 02
Costs
Condo, IPTU, maintenance, and mortgage, all in one place.
- 03
Real return
What you actually keep after costs, by month and year.
- 04
Value & equity
An estimate of what each property is worth, and how much of it is yours after the mortgage.
- 05
Rent vs. market
How your rent compares to similar places nearby — and whether you're charging below market.
- 06
Portfolio summary
Every rental at a glance: total collected, net, and which one's lagging.
05
Track record & screening
Reputation on Mabenn comes from real events, not opinions — no fake reviews, no star ratings, just the receipts.
- 01
Reputation
On-time rent, settled bills, fast replies, fair adjustments, contracts honored — all of it counts, for landlord and tenant.
- 02
Shareable anywhere
Verifiable and portable: show it to any future landlord or tenant, on Mabenn or off. A strong record helps good tenants win the next place.
- 03
Tenant screening
Before signing, check a prospective tenant's credit (Serasa/SPC) alongside their Mabenn track record.
All the management. None of the manager.
Property managers charge 8–12% for what's mostly tracking, paperwork, and chasing payments. Mabenn does that — automatically, for both sides — for a flat monthly price that doesn't scale with your rent. You handle the property. Mabenn handles the know-how.

Why we built Mabenn.
Lucas has rented across Brazil his whole life. He's lived in places where he never once spoke to the owner — every request for a repair went through two layers of people before anything happened, if it happened at all. And every move started with the same scramble: finding a guarantor who owned at least two properties, just to be allowed to sign.
Brandon rents an apartment in Florianópolis from a landlord who manages a few places himself. Every month it's the same — a spreadsheet of rent and utilities, bills over WhatsApp (when they aren't forgotten), payments confirmed by hand, and threads you can never find again. He's also owned and self-managed a rental of his own, so he knows the other side too: the stress of keeping rent, bills, and tenants straight with nothing built for the job.
We've been on both sides of the rental, and we both build software. We kept hitting the same friction year after year, so we built Mabenn to take it out of the relationship — for landlords and tenants alike. Turns out it's pretty useful.

Common questions.
Is Mabenn available yet?
Mabenn is in early access — join the waitlist and we'll let you know when it opens for you. Waitlist signups become founding members: every rental free for the first year, then R$ 39/month per rental, locked for life.
Who is it for?
Small landlords in Brazil who rent directly and manage their own places — and the tenants they rent to. Agents handling a few owners' properties fit too.
Does it replace an imobiliária?
It gives you the structure to manage directly — rent, bills, contracts, and communication in one place. It doesn't show apartments, negotiate on your behalf, or act as your legal representative.
How does Mabenn confirm payments?
Through Open Finance, Brazil's read-only, consent-based bank-sharing system. A licensed provider makes the connection (Mabenn never sees your login) and reads only the transactions that confirm rent and bills. It never moves money, and you can disconnect anytime.
Can Mabenn move money from my account?
No. The bank connection is read-only — Mabenn confirms that payments happened, it never moves or holds money.
If I connect my bank, what can the other side see?
Your transactions are never shown to anyone. Mabenn matches a payment to a charge behind the scenes, then shows just the result — rent paid, the amount. Your balance and other transactions stay private.
What if my tenant doesn't join?
You're still covered — your own bank connection shows rent landing and bills you pay. It's clearer when both sides are in, so Mabenn invites your tenant and gives them their own reasons to join.
Is Mabenn free for tenants?
Yes — free forever, with or without your landlord on Mabenn. Tenants can sign up on their own to start building a payment record they keep.
Get on the tenant waitlist →Can I use it for more than one property — or one I co-own?
Yes — add as many as you have, each with its own contracts and billing. Co-owners each get their own login and the same full view.
Does it replace a lawyer?
No. Mabenn organizes your contracts, key dates, and the notices the Lei do Inquilinato requires — but complex disputes still call for a lawyer.
Is Mabenn LGPD-compliant?
Yes — built for LGPD from day one. Your records are stored in Brazil (São Paulo), with documented retention and audit trails. A few international providers — hosting, analytics, email — operate under data-processing agreements with the safeguards LGPD requires.
Read the full privacy policy →Can I cancel anytime?
Yes. Monthly billing stops at the next renewal; annual prorates the unused months back. No lock-in.
Take back the 8–12%.
Everyone who joins the waitlist becomes a founding member — every rental free for a year, then R$ 39/month per rental, locked for life.
