A calibrated model of debt recycling with interest costs and tax shields: viability under different fiscal regimes and jurisdictions
A new study models debt recycling, where homeowners use home equity to invest and pay off mortgages faster, across Australia, Germany, and Switzerland. The research finds that local interest rates and tax rules are crucial. Rental properties outperform owner-occupied homes because mortgage interest is often tax-deductible for rentals. Surprisingly, Switzerland can see equity erode faster than higher-rate countries in some scenarios. The model uses advanced simulations but does not factor in capital gains taxes or rental vacancies.
What it examines
This paper develops a model for debt recycling, where homeowners use home equity to invest and repay mortgages faster. It includes interest costs and tax benefits, and compares outcomes in Australia, Germany, and Switzerland to show how local financial and tax rules affect the strategy’s success.
What it concludes
Results show debt recycling works best in countries with low interest rates and generous tax benefits, especially for rental properties. The findings help households, lenders, and policymakers understand risks and design better financial products. Future research could refine models for more countries and changing market conditions.

Raw abstract and provenance
Abstract: Debt recycling is a leveraged equity management strategy in which homeowners use accumulated home equity to finance investments, applying the resulting returns to accelerate mortgage repayment. We propose a novel framework to model equity and mortgage dynamics in presence of mortgage interest rates, borrowing costs on equity-backed credit lines, and tax shields arising from interest deductibility.… ▽ More Debt recycling is a leveraged equity management strategy in which homeowners use accumulated home equity to finance investments, applying the resulting returns to accelerate mortgage repayment. We propose a novel framework to model equity and mortgage dynamics in presence of mortgage interest rates, borrowing costs on equity-backed credit lines, and tax shields arising from interest deductibility. The model is calibrated on three jurisdictions -- Australia, Germany, and Switzerland -- representing diverse interest rate environments and fiscal regimes. Results demonstrate that introducing positive interest rates without tax shields contracts success regions and lengthens repayment times, while tax shields partially reverse these effects by reducing effective borrowing costs and adding equity boosts from mortgage interest deductibility. Country-specific outcomes vary systematically, and rental properties consistently outperform owner-occupied housing due to mortgage interest deductibility provisions. △ Less
