PSIS has raised its two, three and four-year mortgage rates by between 10 and 20 basis points.
The co-operative raised its two-year rate by 10 basis points to 6.45 per cent, its three-year rate by 10 bps to 6.95 per cent, and its four-year rate by 20 bps to 7.30 per cent. The new rates are effective immediately.
