For landlords, property managers and rental platforms

Financial infrastructure for the way you rent out

Keep every application in one defined flow

From invitation and onboarding to shortlist and final selection, keep applications, documents and status connected without relying on personal inboxes and separate email threads.


Get applications out of your inbox

Bring SCHUFA, payslips and references into one applicant file. Review applications and build your shortlist with documents in one place, rather than scattered across emails. You make the final rental decision.

Keep applicant data under control

Support your GDPR obligations with secure document storage, controlled access and defined retention and deletion rules. Protect applicant data during the review and after you have made your rental decision.

More ways to handle the deposit

Once you have chosen your tenant, use a deposit account through Secure, a deposit guarantee through Guarantee or your own arrangement. Keep the selected tenant, documents and security connected to the home.

WAYS TO USE KEYHOLE

Keep your existing setup.
Add what you need.

Use the ready-made portal, connect selected workflows to your existing system or integrate available products through the API.
Choose the setup that fits your portfolio, systems and team.

READY-MADE

Use the Keyhole Portal.
Skip the integration.

Want to handle applicant onboarding, financial decision support and deposit products without connecting your own software? The ready-made Keyhole Portal brings the relevant workflows into one workspace, whether you rent out your own properties or manage them for others.

  • Bring applicant invitations, requested information and completion status into one structured flow.
  • Support your rental decision with structured financial information before signing.
  • Invite the selected tenant to Secure or Guarantee when the relevant product becomes available.
  • Follow product status and handle the relevant release or claims process in one place.

Use this ready-made workspace alongside your existing property-management system, without building an integration first.

CONNECTED

Integrate selected tasks.
Use the portal for the rest.

Want to send invitations from your own system while handling applicant review, deposit releases or claims in the Keyhole Portal? Use the API alongside our ready-made portal rather than building every workflow into your own software.

  • Start selected applicant or product invitations from your own system through the API.
  • Use the portal to review status and handle workflows that remain outside your integration.
  • Handle deposit releases or submit claims and supporting documents through the defined portal workflow.
  • Add more API integrations later while keeping other tasks in the portal.

Connect the tasks that matter most to your existing system and use the portal for the workflows you do not want to build yourself.


Landlord_Connected
FULLY INTEGRATED

Build financial products
into your own platform

Want your team or landlord customers to manage Keyhole workflows and products in your own platform? Use our API to build the relevant functionality into your software rather than handling those tasks in the Keyhole Portal.

  • Build applicant invitations and onboarding into the rental workflows you already provide.
  • Offer Secure, Guarantee, Tenant Screening and Rent Accounts through your own platform as they become available.
  • Retrieve completion and product status for display in your own interface.
  • Handle deposit releases and claims through your integrated workflow.

Your developers build the interface and integration; Keyhole provides the underlying workflow and product functionality.

WHAT WE OFFER

Financial products, explained

Explore deposit security, tenant screening and rent-payment infrastructure — designed to work through the portal, alongside your existing system or through the API.

LANDLORD

Guarantee

Put the agreed security in place
— without another cash-deposit account.

Every cash deposit means another setup to establish, follow and close. With Guarantee, an approved tenant pays for a guarantee instead of placing the full amount in cash. Keyhole handles the onboarding and assessment, and you receive the agreed guarantee within its amount and terms. If a valid move-out claim remains unpaid, it can be submitted through the documented claims process.

LANDLORD

Secure

Keep the cash deposit connected to the tenancy.

Secure is designed to connect the cash deposit to the tenancy through a defined digital workflow, so your team can follow its status and handle the relevant release process in one place. The German account structure and terms will be confirmed before launch.

LANDLORD

Tenant Screening

Make the decision on more than an application.

Before you sign, you need more than a form and a first impression. Tenant Screening is designed to provide structured financial decision support for the specific tenancy, so you can assess documented information at the relevant stage while keeping the final rental decision with you.

API PRODUCT

Rent Accounts

Know which tenancy every rent payment belongs to.

When rent payments scale, one bank account — or one account per tenancy — creates reconciliation work for your team. Rent Accounts connects invoices, incoming payments and payouts to the correct tenancy inside your own platform. Payment references and API status updates help your system identify payments as they arrive and keep the payment workflow together.

Rent Accounts is designed for API integration and for platforms or systems managing rent payments at scale.
