Maximum Mortgage
How to Get the Highest Possible Mortgage

One of the key questions in real estate financing is what the maximum Mortgage amount can be. In practice, there are clear rules—but at the same time, there is also some flexibility that is often underestimated.

What is the maximum Mortgage amount?

Banks typically finance owner-occupied properties up to 80% of the property’s value—a minimum of 20% down payment is required. Those who can’t come up with that much will have a hard time: Higher Loan-to-value ratios are possible only in exceptional cases, such as when there are additional assets, an excellent credit rating, or other collateral.

However, such so-called options are rare and must be carefully considered. One thing that always applies, though, is that mortgage lenders calculate differently, which is why the maximum Mortgage amount varies from mortgage lender to mortgage lender. This flexibility can be used to your advantage.

Mortgage Structure
First and Second Mortgages

To understand how mortgage lenders calculate the maximum mortgage amount, you need to understand the “system of so-called first and second mortgages.” This is because a mortgage is usually divided into two parts:

First Mortgage
up to approx. 65% of the property value 

Second Mortgage
from 65% to 80% 

Since a second Mortgage carries a higher risk for the bank, it must be repaid within 15 years or by the time the borrower retires.

A higher Mortgage means a higher risk for the bank and, as a result, usually higher interest rates for you as the Borrower. There are many ways to improve your credit score and thus secure better Mortgage rates.

Liquid Assets
Minimum Down Payment

To purchase a home to live in, you need at least 20% —of which at least 10% must come from , i.e., excluding pension fund assets.

Equity includes:

  • Savings 
  • Securities 
  • Gifts
  • Lot already purchased with own funds
  • (withdrawal or Pledge) 
  • (with restrictions) 

So-called “owner contributions” (e.g., Renovations that a property owner performs on their own property) can also be partially taken into account. Banks are generally more likely to accept owner contributions (Pension funds and insurance companies rarely do), but even banks have become very restrictive in this regard in recent years.

Affordability
How much income do I need?

In addition to equity, affordability is crucial.

Rule of thumb: Calculated housing costs should not exceed one-third of gross income.

In this context, banks do not base their calculations on current interest rates, but rather on:

  • estimated interest rates (4.5% to 5.5%) 
  • Maintenance costs (0.7% to 1% of the property value)
  • Ancillary costs
  • Amortization

More and more mortgage lenders are offering a flat interest rate for both the first and second mortgages. In many cases, this rate is 4.5% or a maximum of 5%. In terms of Affordability, this “flat interest rate” is advantageous for homebuyers. Nevertheless, the requirements are strict, and it takes a significant amount of capital and income to buy a home today.

Example
Financing a property

For a purchase price of CHF 1,000,000, the typical breakdown is as follows:

  • Equity: CHF 200,000 
  • Mortgage: CHF 800,000 

Estimated housing costs can quickly exceed CHF 55,000 per year.

Income must be three times higher than the imputed costs. This results in a required income of more than 160,000 Swiss francs.

Guide
Maximum Mortgage

Anyone looking to secure a large Mortgage should take targeted steps to optimize their financial situation. Key factors include income, equity, Affordability, and choosing the right Mortgage lender. Banks, in particular, tend to have a Loan-to-value ratio that extends right up to the limit. Pension funds and insurance companies are generally much stricter and tend to take a more conservative approach to property valuation. So if you want to maximize your Mortgage amount, a bank is the right place to go.

Top Tips for Getting the Best Possible Mortgage

  • Various Options

    Banks use different calculation methods (Maintenance costs, imputed interest rate, etc.). What one mortgage lender deems “unfeasible financing” may still be possible with another, depending on the situation. Tip: Contact multiple banks.

  • Income

    List all sources of income. If you’re working reduced hours, some mortgage lenders will assume you’ll be working more hours if that’s part of your plan. Depending on your situation, there may be other ways to optimize your application.

  • Structuring Equity Wisely

    Determine which assets can be used and how they can be utilized or used as collateral. Mortgage lenders apply different methods for including assets in the calculation of equity.

  • Reduce obligations

    People who have less debt, no Loans or leases, and who also reduce their other ongoing expenses generally have a better credit rating and thus qualify for better interest rates. Not all mortgage lenders factor ongoing obligations into their Affordability calculations in the same way.

  • By far the most important tip

    Compare multiple providers—each calculates differently. Enter your details at . In just a few minutes, the system will automatically check with more than 30 Mortgage lenders to see if financing is available. 

Conclusion

With good preparation and the right comparison, you can often significantly increase the amount of your Mortgage.

FAQ

Frequently Asked Questions
Answers regarding the maximum Loan-to-value ratio

A mortgage with 100% financing is generally possible, but limited to exceptional cases—such as when there is significant assets, or an excellent credit rating. For most buyers, the maximum Mortgage is 80% of the property’s value; in some cases, it may be as high as 90%.

Not all mortgage lenders accept all types of assets as equity. It is therefore important to clarify this when financing is tight.

  • Savings
  • Securities
  • Life insurance
  • Gifts
  • Pillar 3a
  • Lot already purchased
  • Loans (depending on terms and conditions)
  • Pension fund (in part) 
  • Personal contributions (depending on the bank) 

The loan-to-value ratio is the ratio of the mortgage amount to the property value.

Example
CHF 800,000 Mortgage
CHF 1 million property value
results in: 80% Loan-to-value ratio

It’s important to know that the loan-to-value ratio isn’t the same for all mortgage lenders. This is because they may apply different standards when appraising the property or use different appraisal tools. Differences of 10 percent can easily arise during the appraisal process. It’s therefore important to get quotes from as many mortgage lenders as possible.

Mortgage platforms such as HYPOTHEKE.ch can help with this:  

The Mortgage must be repaid to a loan-to-value ratio of 65 percent within 15 years or by the time of retirement.

Depending on the individual circumstances, mortgage lenders may also require faster Amortization or higher monthly payments. Those nearing retirement are generally well advised to set their Mortgage at a maximum of 65 percent of the property’s value. Read more here: Mortgage Amortization and Retirement

Rule of thumb
max. 33% of gross income

Every mortgage lender calculates differently. It can therefore be worthwhile to get as many offers as possible. If a mortgage lender’s calculations are favorable for your personal situation, you may qualify for a higher Mortgage and/or your credit rating may improve. This results in better interest rates.

Whether this is possible depends on the individual case—the key factors are income, age, and the value of the property.

Not all mortgage lenders go all the way when increasing an existing Mortgage.

Don't forget

As you get older, it becomes significantly more difficult to increase your Mortgage amount. For many people, it is therefore a good idea not to pay down the Mortgage too quickly or to draw up a clear long-term financial plan in advance. Read more here: Mortgages and Retirement

It’s rarely possible to secure a large Mortgage later in life. As people age, their income decreases due to retirement—while mortgage lenders’ requirements become more stringent.

If the property value drops, the Loan-to-value ratio automatically increases—with unpleasant consequences: Additional financing may become necessary, and the deteriorates noticeably.

In practice, real estate prices must decline noticeably over an extended period before mortgage lenders take action. In many cases, a good solution can be found with mortgage lenders. Particularly during the term of the mortgage, the risk that refinancing will be necessary due to falling real estate prices is low. This is also because real estate prices have been rising for a long time and a “safety margin” exists. 

The best way to determine the maximum Mortgage amount for your situation is through personalized calculations, comparing multiple lenders, and developing a clear financial strategy—supplemented by skillful negotiation and the use of mortgage platforms.
