Hard Cash - Fiddlers On The Roof (Monday, 7.30 p.m., BBC1) has a timely tale for those planning to take advantage of the rent-a-room tax-break scheme. It tells of the Kensington tenant from hell - a well-spoken woman from London who used every trick in the book to stay as long as possible rent-free.
It also reveals rogue workmen's schemes to rip-off clients. A pensioner was charged £5,000 for an alarm he didn't need; a householder was swindled via her central heating system; and plumbers pretended to fit new parts to washing machines.
Once a tiny rural village, Tallaght, Co Dublin, now has the population of a small city. Leargas - 30 Years A Growing: The Story of Tallaght (Tuesday, 7 p.m., RTE1) reports on its population of 85,000 and its expanding industrial hinterland.
Karen and Ivan are relocating from Britain and had originally hoped to buy a house in Sandymount or Ballsbridge, but they are now looking at a house in Greystones, as House Hunters (Thursday, 8.30 p.m., RTE1) reports. Mark and Judith hoped to buy a house in Blanchardstown but they were priced out of the market and are now looking in Sligo.
The programme also looks at how the costs of buying and selling a home can vary widely, depending on the solicitor or estate agent used.
There are more slaves in the world today than at any other time in history. Charlie Bird and Caroline Bleahen travelled to India and Brazil for Slaves Without Chains (Thursday, 9.35 p.m., RTE1). There are 26 million slaves in the world and they are cheaper now than they were over 100 years ago.
