Liquidity reserve

The liquidity reserve is a purposefully set aside buffer of freely available funds that protects property owners and investors when unexpected expenses arise or income fails to materialize-such as during periods of vacancy, major repairs, interest rate adjustments, or economic crises. It serves as a financial safety net that prevents unplanned expenses from escalating into a liquidity crisis that could threaten the owner’s livelihood. When granting real estate loans, banks are increasingly verifying whether the borrower can demonstrate that they maintain such a reserve.

Recommended Amount and Composition

As a rule of thumb for private individuals with one or a few rental units: at least three to six months’ net base rent per unit as a free reserve, in addition to the ongoing maintenance reserve. For owners of condominiums in a homeowners’ association (WEG), the community’s maintenance reserve is no substitute for their own reserve-because extraordinary resolutions regarding special assessments can generate significant one-time costs on short notice.

Investors with larger portfolios work with a liquidity plan that forecasts income and expenses on a monthly basis and ensures a defined minimum buffer. A clear separation is recommended: an operational buffer for ongoing irregularities (loss of rent, minor repairs) and a strategic buffer for larger investments or follow-on financing. Both components should be held in secure investment forms that are readily available.

Liquidity Reserve and Real Estate Financing

When purchasing real estate, many banks not only require equity to cover the purchase price and ancillary costs but also verify whether any free liquidity remains after the transaction is completed. A borrower who contributes all of their equity to the financing and holds no reserve is viewed more critically by credit-conscious banks. Some financial institutions stipulate in their internal guidelines a minimum liquidity reserve of one to three months’ gross income. The reserve must not be tied up in the property itself or other illiquid assets.

During the low-interest-rate period up to 2022, many buyers neglected the liquidity reserve because refinancing was affordable and loans were readily available. With the rise in interest rates since 2022, this has fundamentally changed: refinancing is more expensive, banks are stricter-and those without a reserve quickly find themselves in trouble. The interest rate adjustment phase has shown how important this buffer is for the financial stability of property owners.

Vacancy Risk and Seasonal Fluctuations

The liquidity reserve becomes particularly relevant during periods of vacancy between two tenancies. In the Nuremberg metropolitan area, vacancies lasting between six weeks and three months are quite realistic with active marketing-longer if renovations are required. During this time, mortgage payments, maintenance fees, and insurance premiums continue to accrue. Those without a reserve must take out expensive bridge loans or-in the worst case-sell the property below market value.

The same applies to periods when tenants fail to pay their rent or pay late. Rent losses due to insolvency or unwillingness to pay can occur despite tenant credit checks. The liquidity reserve bridges the gap until legal resolution (reminder, termination, eviction lawsuit), which, based on experience in Germany, can take six to twelve months.

Practical Tip for Property Owners in Nuremberg and Franconia

In Nuremberg and the metropolitan region, many buyers purchase properties at their financial limit due to high purchase prices. We recommend: Never commit 100% of your available equity to financing. Keep at least €10,000-20,000 (depending on the property size) as an untouched buffer in a money market account. This amount will save you from the predicament of having to take out an expensive installment loan at short notice in the event of a broken heating system or a month of vacancy.

If you own multiple units, we also recommend calculating the reserve separately for each unit rather than trying to use a single reserve for the entire portfolio. Portfolio effects can be deceptive: if several tenants move out at the same time or a major renovation is required, the buffer can be quickly depleted. A simple spreadsheet that tracks income, operating costs, and reserves for each unit provides transparency and helps you make timely adjustments.

Frequently Asked Questions

How does the liquidity reserve differ from the maintenance reserve?

The maintenance reserve is earmarked for future repairs and renovations. The liquidity reserve is a general buffer for all unforeseen expenses and loss of income-it can be used flexibly and should be available at short notice at any time. Both funds should be maintained in parallel; one does not replace the other.

Do I have to disclose the liquidity reserve to the bank?

When granting loans, banks typically require bank statements and proof of assets. Having a liquidity reserve has a positive effect on your credit rating. There is no legal obligation to explicitly prove it, but it significantly improves your negotiating position-especially if you are aiming for better terms or a higher loan amount.

Can I hold the liquidity reserve in securities?

Only to a limited extent. Call money or money market funds are ideal because they are available at any time. Stocks or funds with price fluctuations are less suitable because the value may be low at the worst possible moment (when the reserve is needed). Recommendation: Hold at least half of the reserve in instruments with guaranteed availability.

How does the need for a liquidity reserve change with the age of the property?

The older a property is, the higher the reserve should be. For buildings over 30 years old, the likelihood of major repairs (heating, roof, windows, plumbing) increases disproportionately. As a guideline: For new buildings, three months’ net rent is sufficient; for older buildings over 30 years old, it should be at least six months’ rent-in addition to a well-funded maintenance reserve.

Liquidity Reserve for Condominium Ownership

Anyone who owns a condominium as an investment must, in addition to their own liquidity reserve, take into account that the condominium association may decide on special assessments at short notice-for example, for urgent repairs to common property (roof, elevator, heating)-if the association’s maintenance reserve is insufficient. Depending on the unit’s share and the condition of the property, such special assessments can amount to several thousand euros and must generally be paid within a few weeks.

In Nuremberg, there are many older apartment buildings whose homeowners’ association maintenance reserves have been underfunded for years. A building in need of renovation with an insufficient reserve is a clear red flag for buyers. We recommend reviewing the HOA financial statements for the past three years and the minutes of the owners’ meetings before purchasing a condominium-both provide insight into upcoming major projects and the financial stability of the association. A well-funded HOA reserve significantly reduces the risk of unexpected special assessments.

How should the liquidity reserve be invested?

The liquidity reserve must be available at short notice at all times. Suitable investment forms include overnight deposit accounts at reputable banks, money market funds, or short-term fixed-income deposits with daily access. Stocks, real estate funds, or long-term fixed-income bonds are unsuitable, as their value may fall at the wrong time or they cannot be liquidated immediately. With interest rates having risen since 2022, overnight deposit accounts are once again yielding acceptable returns of 2-4%-meaning the opportunity costs of holding liquidity are lower than during the low-interest-rate phase. Nevertheless, the reserve is not an investment intended to generate returns, but rather a safety buffer.
