International healthcare insurance policyholders planning to invest in properties may wish to consider the German cities of Bremerhaven, Leipzig and Chemnitz.
These will "get the best return in investment", according to James Kirkman, property consultant at ProVenture Property.
He explained yields of between nine and 13 per cent can be realised in these locations, whereas Berlin's average yield is around six per cent.
When returns are high, finance can be attained with reasonable conditions and investors are confident, it generally indicates "future potential and future capital appreciation" in a location, the expert explained.
In Germany "nobody really knows" what will happen to the property market in two decades, but Mr Kirkman, who is also involved with German-property-for-sale.com, stated that his firm aims to "guarantee a return for our investors".
This generally refers to locations with high yields, which points towards these three cities as providing the best opportunities to make money, the expert asserted.
He had previously described how a large proportion of Germans rent their dwellings, which keeps real estate values low and insulated the property market from the global financial crisis.
