After being improved the properties were let to those on intermittent and low incomes. A return of five per cent on capital was obtained as promised to Ruskin; any excess over the five per cent was reinvested within the properties for the benefit of the tenants. Rent arrears were not tolerated, and bad debts were minimal. As Hill said, "Extreme punctuality, and diligence in collecting rents, and a strict determination that they shall be paid regularly, have accomplished this." In consequence of her prudent management, Hill was able to attract new backers, and by 1874 she had 15 housing schemes with around 3,000 tenants.
