Mortgage Interest: Pricing Factors Explained

The mortgage interest rate is the price of mortgage-backed real estate loans – it arises from the capital market, property and credit rating.

Last updated: 18 July 2026 · Reviewed by Jürgen Kronawitter

In brief: The Mortgage rate means the borrowing rate for mortgage-backed real estate loans. It consists of the refinancing interest rate of the lenders (oriented on the Pfandbrief or swap curve) and an individual margin that reflects loan-to-value ratio, property quality, creditworthiness and maturity. Fixed sentences without examining the individual case are not serious.

How does the mortgage rate arise?

Lenders refinance real estate loans on the capital market – via Pfandbriefe, deposits or swaps. On this base rate, they add a margin that reflects the individual risk. The main drivers:

  • loan-to-value ratioLTV): The higher the expiry, the higher the margin – often in stages (60 %/80 %).
  • fixed-rate period and Term: Longer tie costs ups or downs depending on the yield curve.
  • Property and location: Asset class, condition, third-party usability, lease status.
  • Credit quality and cash flow: Creditworthiness the borrower; and DSCR of the property.

Why Interest Rate Comparisons Work Differently for Professionals

Unlike in private customer business, there is no price list for commercial real estate finance: each condition is the result of a case-by-case examination and – crucially – of the competition under lenders. The same request can generate noticeably different margins depending on the addressee, because each bank, each debt fund and each insurance company has its own lending criteria. A professionally prepared financing case, placed in parallel at suitable addresses, improves the interest rate measurably more than any negotiation with the existing bank alone.
