Buying Property with Equity: How Much Is Needed?

Article L-0085 · 01.10.2026 · 7 min. read · Joé Christian Ewrard

What Do You Need Equity for When Buying a Property?

Equity is the part of the financing that you cover using your own funds. This may include balances in bank accounts, investments available at short notice and property assets you already own. Certain savings plans or documented gifts may also be taken into account. Whether and to what extent a bank recognises these assets depends on their availability and its individual assessment.

Equity serves two purposes. It covers costs that are not directly reflected in the property's value. At the same time, it reduces the amount you need to borrow. This lowers the risk for the bank and, in many cases, the monthly financial burden for you.

The key question is therefore not only how much money is available. It is equally important to consider what it will be used for. Anyone who puts all their funds into the purchase and has no reserves left afterwards may start out under financial pressure despite contributing a substantial amount of equity.

A sound plan therefore considers three areas separately: the purchase price, the incidental purchase costs and the financial buffer remaining after handover. Only this overall assessment shows whether the available capital is genuinely sufficient.

Why the Incidental Purchase Costs Are So Important

There are additional expenses on top of the purchase price. These usually include property transfer tax, notary and land registry fees and, where applicable, the estate agent's commission. The actual cost depends, among other things, on the federal state, the purchase agreement and the agreed allocation of the estate agent's fees.

From the bank's perspective, these expenses generally do not increase the property's value by a corresponding amount. After all, notarisation, a land registry entry or a tax payment does not make the house larger or easier to sell. Many banks therefore expect buyers to be able to cover at least the incidental costs using their own funds.

There are also expenses that are easily overlooked. These may include a necessary move, minor work before moving in, new insurance policies or initial furnishings. With an older house, repairs may also be required immediately after handover even though they did not appear urgent during the viewing.

You should therefore have a complete cost breakdown prepared before applying for financing. It should be tailored to the specific property. A rough rule of thumb is no substitute for this assessment, as the plot, the condition of the building, the structure of the contract and the estate agent's fee affect every purchase differently.

How Banks Assess Equity and Loan-to-Value Ratios

The bank does not look at the purchase price alone. It determines its own value for the property and considers the amount for which the property can serve as long-term security. This value may differ from the agreed purchase price.

The loan-to-value ratio is determined by the relationship between the loan and the property value assessed by the bank. The more financing is required in relation to the security, the higher the bank's risk. This may affect the terms, the required repayment rate and whether financing is feasible in principle.

A high purchase price therefore does not automatically mean that the bank will accept the same amount as the property’s value. This is particularly important when several prospective buyers drive up the price or a property has unusual features. Extensive renovation requirements can also affect the valuation.

Equity can improve the loan-to-value ratio. However, it is not only the amount that matters. Banks also check where the money comes from and whether it will be available in time. Bank statements, contractual documents or proof of a gift should therefore be provided in full at an early stage.

What Banks Expect from Buyers Today

Banks generally assess three things together: the buyer’s financial situation, the quality of the property as security and the plausibility of the overall project. A good financing arrangement must be convincing in all three areas.

For the buyer, the focus is on regular income, ongoing commitments, household expenses and possible future changes. Fixed-term employment, self-employment or income from abroad do not automatically rule out financing. However, they often result in a more detailed assessment and a greater need for documentation.

For the property, location, condition, usability and resale potential all play a role. A well-maintained house with clear, verifiable plans is easier for a bank to assess than a building with unclarified alterations, substantial renovation requirements or a use that is difficult to compare.

A realistic household budget is equally important. The monthly loan repayment must not only be affordable under current conditions. There should also be room for maintenance, rising running costs and personal changes. Banks use their own calculation models for this. Nevertheless, your personal planning should be more precise, because you know your daily life and your goals better.

Is It Possible to Buy with Little or No Equity?

Financing with little equity may be possible in principle. However, it depends more heavily on a stable income, a strong credit profile and a property that can be reliably valued. Not every bank offers this type of financing, and not every house is suitable for it.

The fewer personal funds are used, the smaller the safety margin. If a sale becomes necessary sooner than planned at a later date, the outstanding debt, sale value and additional costs may come together unfavourably. This risk should be discussed openly, even if the purchase appears easily affordable today.

There is a second risk for buyers: all available funds are used for the ancillary purchase costs, while the house incurs unexpected expenses shortly after move-in. A faulty heating system, damp or necessary roof work do not follow the financing plan.

Financing without a large equity contribution should therefore not begin with the question of whether a bank will approve it. What matters more is whether it suits your household, your life plans and the specific property in the long term. Approval alone does not make a financing arrangement sensible.

How Much Should Be Kept in Reserve After the Purchase?

There is no single suitable reserve amount for every household. A new, well-documented building has different requirements from an older detached house. Family size, vehicles, job security and planned modernisation work also affect the amount needed.

The reserve should be available at short notice. Capital that can only be sold at a loss or is firmly earmarked for retirement provision may not fulfil this purpose. The financing consultation should therefore clearly distinguish between usable equity and money that is deliberately left untouched.

In practice, buyers often initially focus only on the monthly repayment. After handover, several smaller expenses then arise at the same time. Each one would be manageable on its own, but together they create financial pressure. Having your own financial buffer protects you from having to finance necessary work through expensive short-term loans.

Anyone considering committing their entire assets out of concern that their application may be rejected should pause. A bank may welcome a larger equity contribution. However, maintaining an adequate liquidity reserve may be more important for your day-to-day life. This trade-off should be considered as part of personalised mortgage advice.

What Requires Particular Attention in the Eifel and Around Trier?

The Eifelkreis Bitburg-Prüm, Trier and Trier-Saarburg, as well as the Vulkaneifel, offer a wide variety of properties. Alongside urban apartments, there are detached houses, former agricultural buildings and properties in smaller towns and villages. Their condition, plots, outbuildings and modernisation requirements can vary considerably.

For older houses, the financing should cover more than just the purchase. Planned work must be professionally assessed and calculated in a transparent manner. Banks often want to understand which measures are necessary, which can be carried out later and how the costs are to be financed. A general contingency allowance with no connection to the property is less convincing than realistic planning.

The proximity to the border with Luxemburg adds another particular consideration. Some buyers earn their income in the neighbouring country but purchase the property in Germany. In such cases, additional documentation regarding employment, income and the tax situation may be required. The documents required vary from bank to bank. Tax and legal matters should be clarified with a tax adviser, lawyer or notary.

A regionally experienced estate agent can identify at an early stage which property documents may still be needed for the financing. These may include verifiable floor-area details, documents relating to alterations or information about the property's energy efficiency. The lending decision remains with the bank. However, thorough preparation can reduce follow-up questions and uncertainty.

How to Prepare Your Financing Properly

Do not start with the maximum purchase price. First determine what monthly financial commitment feels comfortably manageable over the long term. Take into account not only the loan instalment, but also ongoing property costs, maintenance and your other living expenses.

Next, organise your equity. Separate available funds, tied-up investments and the reserve you wish to retain. If money is to come from family, it must be clarified at an early stage whether it is a gift or a loan. The legal and tax arrangements should be handled by qualified professionals.

Only then should a specific property be considered in full. The purchase price, ancillary purchase costs, modernisation and reserve together determine the capital required. For renovation work, reliable assessments from specialist contractors are helpful. Assumptions or estimates that are too tight may later place the entire financing under pressure.

Have the financing formally approved before the purchase agreement is notarised. A general preliminary assessment is helpful, but it does not replace the decision on the specific property. The notary explains the purchase agreement and its legal consequences. An estate agent cannot replace personalised legal or tax advice.

First determine your available equity, the reserve you wish to retain and a monthly financial commitment that is sustainable over the long term. Then have the ancillary purchase costs, modernisation requirements and bank valuation assessed for the specific property. PRIOCASA can assist you in Bitburg, the Eifel, the Trier area and along the border with Luxemburg in compiling the property information and preparing for the financing consultation.

Frequently Asked Questions

Do I always have to pay the ancillary purchase costs from my own equity?

Not necessarily, but many banks expect this. If the ancillary costs are also financed, the amount of credit required and the risk increase. Whether this is possible and advisable depends on your creditworthiness, the property and the bank's requirements.

Does a building society savings agreement count as equity?

Available funds can generally be taken into account. The key factors are the status of the contract, availability and any applicable conditions. The financing bank will assess the amount it can actually recognise as equity.

Should I put all my savings into the purchase?

As a rule, it is advisable to retain an appropriate reserve. The amount will depend on the condition of the property, the household and any planned work. An independent mortgage adviser can compare different options.

Why does the bank value the house lower than the purchase price?

The bank uses its own valuation methods and views the property as security for the loan. An agreed purchase price may be influenced by high demand, special features or the buyer's personal willingness to pay. The difference may create a need for additional equity.

Can income from Luxembourg make financing more difficult?

It may require a more detailed assessment and additional documentation. This does not automatically mean that obtaining financing will be more difficult or impossible. You should discuss any tax and legal considerations with appropriately qualified advisers.
