A prominent UK estate agency has laid bare the true cost of no-deposit mortgages, warning that borrowers who skip saving altogether could end up paying tens of thousands of pounds more over the lifetime of their loan than those who put down even a modest sum. The analysis lands at a pivotal moment: 100% loan-to-value products, largely absent from the market since the 2008 financial crisis, have quietly returned via lenders including Skipton Building Society, April Mortgages and Gable, marketed explicitly at renters locked out by deposit requirements. The appeal is obvious, but the arithmetic behind these products deserves far more scrutiny than it has received.
