Double burden

Double Burden - In the context of real estate, a double burden arises when a buyer has to pay both rent for their current home and mortgage payments for the new property at the same time for a period of time. This transition period between the purchase agreement (transfer of ownership) and the actual move-in can last several months and represents a significant financial burden that must be taken into account when planning financing.

Causes of the double burden

The double burden arises from the time gap between various milestones in the real estate purchase:

• Payment of the purchase price before moving in: After the purchase agreement is signed and the notary issues the notice of due date, the purchase price is paid-mortgage payments begin upon disbursement, but moving in often does not occur until weeks or months later
• Renovation/remodeling: The new property must be renovated or remodeled before moving in-rent continues to accrue during this time
• Notice periods for the rental apartment: The statutory notice period is 3 months to the end of the month-if the timing is unfavorable, there can be up to 4 months of overlap
• Mortgage financing for new construction: In developer purchase agreements, installment payments are made according to construction progress (MaBV) - Commitment interest and partial installments accrue, while moving in is only possible upon completion

Typical Duration and Costs

The double burden typically lasts 2-6 months for a standard real estate purchase. For new construction or extensive renovations, it can last 6-12 months. Sample calculation:

• Previous base rent: €900/month
• New mortgage payment: €1,400/month
• Duration of the double burden: 4 months
• Additional cost: €3,600 (4 × €900) or total cost €9,200 (4 × €2,300)

Strategies for Minimizing the Double Burden

The double burden can be reduced through careful planning, but rarely completely avoided:

• Terminate the lease only after notarization: Do not terminate the rental lease until the purchase contract has been notarized-not before, to avoid the risk of the purchase falling through
• Coordinate the handover date: In the purchase agreement, agree on the date of transfer of ownership so that it coincides with the end of the rental apartment’s notice period, if possible
• Interest-free grace period: For new construction and renovation financing, negotiate the longest possible interest-free grace period in the loan agreement (12-18 months instead of the usual 3-6 months) to reduce the financial burden during the construction phase
• Concurrent renovation: Plan and largely complete renovation work on the new property within the notice period for the old apartment

Double Expense After Financing Phase - Typical Scenarios

Scenario	Duration of Double Expense	Monthly Additional Costs	Total Expense
Standard purchase of existing apartment, immediate move-in	1-2 months	€900 (previous rent)	€900-1,800
Standard purchase of an existing apartment requiring renovation	3-5 months	€900	€2,700-4,500
Purchase from a developer, no delay	6-12 months	€900 + commitment interest	€5,400-10,800
Purchase from a developer with construction delay	12-18 months	€900 + commitment interest	€10,800-16,200
Attic conversion during lease term	4-8 months	€900	€3,600-7,200

Based on: Sample household, previous rent €900/month. Pre-financing interest approx. 0.25%/month on undrawn loan amount (€300,000 = €750/month).

Practical Tip for Homeowners in Nuremberg and Franconia

In Nuremberg, the average processing time from the purchase contract to the transfer of ownership is approximately 6-10 weeks-plus any renovation work and the notice period for the rental apartment. We recommend that our clients include this double expense as a fixed item in their financial planning: Plan for a buffer of at least 3 months’ rent and keep this amount available as a liquid reserve. When purchasing from developers in Nuremberg’s new development areas-Lichtenreuth, Tiefes Feld, Brunecker Straße-you should plan particularly conservatively due to frequent construction delays and, if in doubt, negotiate the interest-free period to 18 months. In the current market situation, well-informed buyers can occasionally agree on a rent-free transition period with the previous tenant if the latter needs more time to move out.

Frequently Asked Questions

How can I minimize the double burden?

The most important steps: Terminate the lease for the rental apartment only after the notarization (not before-if the purchase falls through, you would be without a home), set the handover date in the purchase contract as late as possible (gives you time to give notice and move), agree to a long interest-free grace period for new construction, and plan renovation work on the new property to coincide with the notice period for the old apartment. Ideally, the overlap is only 4-6 weeks. If you need a particularly high degree of planning certainty, you can also terminate the lease with the landlord individually via a termination agreement instead of waiting for the statutory notice period to expire.

Does the bank take the double burden into account when granting a loan?

Yes - reputable banks factor the double-burden phase into their capital requirements planning and assess whether the borrower can financially bridge the transition period. This means: The liquidity reserve for the double-burden phase should be discussed during the initial consultation. Some banks offer payment-free introductory years (so-called deferred principal payments for the initial period) or a lower initial principal repayment rate to reduce the burden during the transition phase. Be sure to ask your financial advisor specifically about these options and have them calculate various scenarios for you.

Can I claim the double burden for tax purposes?

The rent for your previous apartment is generally not tax-deductible (personal expense). However, for a rented property, you can deduct the loan payments (interest portion) and commitment fees as income-related expenses-even if the rental does not begin until later, provided that the intention to rent is verifiable and you are actively seeking a tenant. In such cases, the tax office will examine whether there was a serious intention to rent out the property-evidence such as classified ads, real estate agent contracts, or condominium association minutes is helpful. If you are using the property yourself, the double burden is not taken into account for tax purposes.
