As a new 440-unit Build-to-Rent (BTR) development is announced, a separate study has found that amid claims by some that the sector is expensive for renters, it is actually more affordable than the Private Rental Sector (PRS). While the BTR segment remains relatively niche with the majority of the developments available in just 20 English cities, on a rent-to-income basis, it is considered affordable by certain standards set by the Office for National Statistics.
