Property Funding Gaps: Causes and Solutions

The financing gap is the distance between what a project costs and what Bank and equity cover – and it is structurable.

Last updated: 18 July 2026 · Reviewed by Jürgen Kronawitter

In brief: A Funding gap arises if the available funds – equity plus first-ranking bank financing – are not sufficient to cover the total cost of a real estate project. Typical causes are conservative mortgage lending values, increased construction costs or bound equity. It is structured: via mezzanine capital, subordinated loan, Whole Loans or capital release from the portfolio.

How do funding gaps arise?

  • Rating delta: The bank finances on the basis of the conservative mortgage lending value The purchase price is above that.
  • lending limit: the first tier is the end of 60–80 %;Lending limitThe rest needs other capital.
  • Cost increases: Construction and interest costs grow during the project – the original structure is no longer sufficient.
  • Bound equity: the funds are invested in ongoing projects or in existing projects instead of being available.
  • Time gaps: Revenues flow later than costs are incurred – the liquidity gap as a special case.

Solutions: Closing the gap in a structured manner

For permanent gaps between the bank and equity Mezzanine capital and Subordinated loans the standard solution; alternatively, Whole loans the total leverage from one hand. Closing time gaps Bridge finance. Anyone who holds the balance can close the gap on their own: per Additional borrowing Hidden reserves become liquid – often the cheapest “mezzanine” at all.

Gap identified – how to proceed?

The decisive factor is honest analysis: how large is the gap really, is it permanent or temporary, and does the project bear the costs of the additional capital? A gap that can only be closed with overpriced capital is a warning signal for project calculation. We calculate both answers transparently – within the framework of the Free initial estimate with a concrete structural proposal.

Frequently asked questions

Financing gap – briefly answered

How big can a funding gap be?

There is no fixed limit – the decisive factor is whether the project bears the costs of the gap-closing capital. As an orientation: mezzanine tranches usually cover 10 up to 25 % of the total costs; a real own contribution is always necessary.

What is the Difference Between Financing Gap and Liquidity Gap?

The financing gap is a structural shortage of capital over the duration of the project; the liquidity gap is a temporal disintegration of deposits and disbursements. The former is closed with subordinated capital, the latter with bridge or interim finance.

Can I close a gap without a new debt capital?

Yes: additional borrowing of existing properties, contribution of valuable land, partnerships with co-investors or adjustment of the project design. Often, the combination of several building blocks is the most economical solution.
