Frequently Asked Questions

Here is an overview of questions related to construction financing, real estate financing, and home buying that occupy a large portion of our customers. The experts from Finanzleuchte are ready to provide you with answers and explanations.

How is real estate financing calculated?

The calculation of real estate financing depends on four main factors:

  • Capital market
  • Buyer's creditworthiness
  • Property information
  • Financing structure


Capital market

The interest rates for real estate financing are based on the yields of long-term bonds and mortgage bonds. The market interest rate for construction financing is typically about 0.5% higher than the yield of ten-year mortgage bonds. When demand for these mortgage bonds is high, yields and interest rates for real estate financing decrease. Conversely, yields and interest rates rise when demand for mortgage bonds decreases. Over several years, these differences can result in variations of several percentage points. The timing of real estate financing is, therefore, crucial in terms of costs.


Buyer's creditworthiness 

  • The buyer's creditworthiness is determined by various factors, including employment status (employed, self-employed, duration of current employment)
  • income
  • monthly expenses
  • Schufa (credit rating agency in Germany)
  • amount of equity capital; The less external capital needed for real estate financing, the lower the interest costs, and the faster the financing is repaid. Additionally, banks reward a high equity capital ratio with lower interest rates
  • the number of people living in the household


Property information

  • Property-related factors include the type of property (apartment, house, old building, new building)
  • location
  • usage (owner-occupied, rental, residential or commercial use)
  • the entry of a mortgage


Financing structure

  • bank's interest rate
  • the disbursed amount
  • the duration of interest-free availability
  • the fixed interest rate period
  • the initial repayment rate (percentage of the loan amount you want to repay in the first year of the term)
  • the amount of special repayment


Each lender weighs these and other factors according to internal guidelines and conditions, making the calculation of costs not always transparent for outsiders. With our real estate financing calculator, you can estimate the costs of real estate financing quite accurately. Give it a try!

How do I get the most affordable real estate loan?

To get the most affordable real estate loan, the following criteria must be met:

  • Sufficient Equity and Good Creditworthiness
  • Comparison of Offers (we'll do that for you) > arrange a consultation
  • Optimization of Financing Structure (We are happy to provide you with advice on this)


Sufficient Equity

The amount of equity, i.e., how much you can directly pay for your property from your own resources, has a direct positive impact on the loan conditions. If you also have a stable income, have consistently met your previous payment obligations, and have no additional financial burdens apart from living expenses, the bank will view you as a reliable borrower and reward you with a lower interest rate for your planned construction financing or desired real estate loan.

While it is possible to finance the entire purchase price through a loan, with 100 percent or more of the purchase price being provided as credit, banks often charge up to one percent more in interest for such financing. Given the long terms of real estate loans, this can have a noticeable impact.


Comparison of Offers

Conditions for financing change regularly, so it's essential to regularly compare different providers. We can handle this for you - schedule a consultation appointment.Interest Calculator.


Optimization of Financing Structure

Apart from comparing various offers, the financing structure can offer the most significant potential for savings in a real estate loan. Let us provide you with advice - schedule a consultation appointment > consultation appointmen

What does the bank need for real estate financing?

To receive approval for real estate financing or construction financing, you need to provide the bank with numerous documents. These include personal documents about you and your financial situation, as well as information about the property itself. As the latter is usually provided by the seller of the house or the appointed real estate agent, you only need to take care of the personal documents. While missing important documents may not lead to a rejection of your application, it can cause delays in the approval process by the bank.

The most crucial document for obtaining the loan is, of course, the loan application, which we will fill out completely for you, and you will only need to sign it. To assess your creditworthiness, the bank also requires proof of income, typically in the form of salary statements, and often income tax assessments as well. In addition to income from your employment, you may also need to provide evidence of other sources of income, such as rental income from properties. When you apply for a loan through Finanzleuchte, you will receive a list of required documents.

For self-employed individuals, proving income for real estate financing can be more complex. Banks often require income tax assessments and declarations from the previous two years, as well as balance sheets, profit and loss statements, or income-surplus calculations. Additionally, self-employed individuals are often required to present a current business evaluation, which is usually prepared by an accountant.

If you plan to contribute equity to the financing of the property, you will need to provide evidence of this capital, such as bank statements, savings account statements, or investment account statements. Any payment obligations, such as existing loan contracts, also need to be disclosed and documented to the bank. Finally, the bank requires an identity proof, such as a personal identification document or passport.

To ensure that you submit all the necessary documents correctly and expedite the processing by the bank, it is best to consult the experienced financial experts at Finanzleuchte. If you have any questions about your loan, feel free to contact us. We will be glad to answer your questions and provide you with helpful advice.

How does a KfW loan work?

If you want to finance your project through a favorable loan from KfW (Kreditanstalt für Wiederaufbau), you can consult our financial experts. Often, the KfW loan only represents part of the total loan amount needed for financing. Your financial expert will forward your KfW application to the bank, and you will receive the approval or rejection for the requested funding from the bank. The further processing of the loan, such as the disbursement of the loan amount and the repayment of the monthly installments, is handled by the selected financial institution – as an end customer, you have no direct interaction with KfW.

KfW funding is used in construction and real estate financing, as well as for energy-efficient renovation measures of a property. Applying for KfW funding is often a straightforward step towards your optimal financing solution.
