Rent arrears in an apartment building purchase: retention, guarantee or seller liability?

In apartment building acquisitions the parties regularly find rent arrears for some tenants. How those arrears are handled economically and legally is one of the key negotiation points between seller and buyer. Without a clean arrangement, disputes arise later at several levels: allocation of the arrears, responsibility for collection and the effect of payments received after the effective date.

This article sets out the review axes. It covers landlord succession for valid principal leases under section 2 MRG, assignment of open claims under section 1392 ABGB and the notice effect under section 1395 ABGB, the statutory allocation of partial payments under section 1416 ABGB, purchase-price retention, bank guarantee and seller liability and the tenancy background under section 33 MRG.

Why rent arrears are their own review layer

Rent arrears operate on several layers. Economically they reduce the yield of the apartment building and influence the price. Legally they are claims of the landlord against the tenant that arose before the effective date. From a tenancy law perspective they can affect the survival of the lease itself, because qualified arrears combined with section 33 MRG can carry a termination. That combination calls for a structured review, not a boilerplate clause.

The time cut between seller and buyer phase matters. For valid principal leases within the MRG, section 2(1) MRG binds the landlord's successor from handover of the leased premises. Rent claims that arose before the effective date remain with the seller unless they are contractually assigned. The topic page Rent roll and lease agreements orders the underlying tenancy logic.

From the contract negotiation this yields a clear task: time cut, allocation, security and collection have to be aligned. Only then do retention, guarantee or seller liability work economically and legally.

Section 2 MRG: landlord succession and time allocation

Section 2(1) MRG binds the landlord's successor to a valid principal lease from handover of the leased premises, even if the lease is not registered in the land register. Other leases require a separate succession analysis. Section 1120 ABGB does not support a universal statement that every sale leaves every lease unchanged.

The allocation works in practice as follows. Payments received against arrears from the seller period flow to the seller unless the parties agree otherwise. Payments on current rent after the effective date belong to the buyer. This apparently simple line becomes tricky where tenants make partial payments without designation or where seller and buyer share a bank account.

The contract should therefore expressly regulate how payments after the effective date are allocated, who informs tenants about the new bank details and how jointly received payments are treated.

Assignment of open claims: sections 1392 and 1395 ABGB

Where the buyer is to take over the seller's open claims, this is done through assignment under section 1392 ABGB. The assignment is a contract between the previous creditor and the new creditor. For apartment buildings a precise schedule of assigned claims by debtor, legal basis, period and amount is helpful.

Section 1395 ABGB governs the effect against the debtor. Until notification the tenant may still discharge the debt by paying the previous creditor. For the take-over by the buyer this means a clear sequence: first the assignment contract, then a coordinated notice to tenants, then the switch of the bank details. Without the notice, payments to the seller remain discharge-effective.

Economically the assignment only makes sense to the buyer where the collectability of the claims is realistically valued. Booking claims at face value can disappoint on unrecoverable positions; a valued approach with a reassignment clause on non-recovery gives both sides more security.

Allocation of partial payments: section 1416 ABGB

Where a tenant is in arrears across several periods and makes partial payments, allocation is often contested. A clear designation by the payer comes first. If that intention is doubtful or disputed, section 1416 ABGB allocates first to interest and then to principal; among several principal claims the further statutory order applies. That allocation can decide which party receives a payment economically.

In practice clear communication is essential. Tenants receive a payment instruction with a designation upon the switch; the seller stays the point of contact for old arrears; the buyer runs the current rent from the effective date. Without this split, section 1416 ABGB can direct old arrears against new payments and disappoint both parties' expectations.

For the contract this leads to a specific clause. It describes how post-effective-date payments are allocated, which designations are permitted and how disputes over allocation are resolved. That clause is useful in addition to retention or guarantee.

Purchase-price retention, bank guarantee and seller liability

For economic security three instruments are available. A purchase-price retention ties a part of the price with the contract drafter or the escrow agent for a defined period. The buyer receives security against known risks; the seller knows the payout hangs on clear conditions. The retention should be defined in amount, time and mechanic.

A bank guarantee is an alternative. It can be issued for specifically identified risks and gives the buyer independent payment security. For apartment building arrears it is usually appropriate where a larger position must be secured and the bank fees are economically justifiable.

Seller liability is the third category. It works without asset binding because the seller is liable from its remaining assets. It only makes economic sense with a reliable seller or as a supplement to retention or guarantee. The topic page Apartment building sale orders the contract points on the seller side.

Deposit and set-off as a fallback layer

The deposit under section 16b MRG secures legitimate claims arising from the lease. After the lease ends it must be returned with interest to the extent it is not used for those claims. The acquisition review should therefore disclose the balance, investment form and every documented use of the deposit for each lease.

Set-off under section 1438 ABGB requires mutual, similar and enforceable claims. Applying a deposit is not automatically the same as set-off. In addition, the buyer can enforce an old rent claim only if it was validly assigned. Contract clauses should therefore treat deposit use, assignment and any set-off separately.

The contract should record the deposit balance per lease, any prior use and the allocation of the secured claims. This makes it clear who must later return which part of the deposit with interest after the lease ends.

Practical flow and next steps

A structured treatment of rent arrears starts before the contract negotiation with an analysis of the rent roll and the payment history. Then comes the choice of model: continued collection by the seller, assignment to the buyer with valuation or price reduction. Then the securities, notices and tenant communication are aligned.
