NatWest has lowered selected rates, effective from 24 September.

The bank is cutting rates by as much as 22 basis points (bps) across mortgages for new business. 

This includes the fee-free two-year fixed residential purchase mortgage at 60% loan to value (LTV), which has been cut from 5.36% to 5.28%. The corresponding product with a £995 fee has seen a smaller reduction of 2bps to 5.13%, while the option with a £1,495 fee has been cut from 5.1% to 5.08%. 

At 75% LTV, the two-year fixes with a £995 and £1,495 fee have been lowered by 1bps each, bringing them to 5.24% and 5.19% respectively. 

At the upper end, NatWest has cut the rate of the two-year fixed purchase product at 90% LTV with no fee, from 5.56% to 5.53%, and the deal with a £995 fee will be cut from 5.56% to 5.53%. Further, the fee-free deal at 95% LTV has been reduced by 17bps to 5.73%. 

Cuts have also been made to five-year fixed residential purchase deals, remortgages, shared equity, green and buy-to-let (BTL) products.

Keystone Property Finance cuts rates by up to 15bps 

Keystone Property Finance has reduced its BTL product rates by as much as 15bps. 

Now, its standard product rate at 70% LTV is priced at 3.74%, the expat mortgage at 65% LTV begins at 5.34%, and the holiday let mortgage rate at 65% LTV starts at 6.04%. 

Keystone Property Finance’s product transfer and PT Plus rates start from 5.54% at 65% LTV, the refurb to let exit product rate begins from 5.54% at 65% LTV and the semi-commercial rate starts from 7.34% at the same tier. 

Elise Coole, managing director of Keystone Property Finance, said: “Landlords’ circumstances and borrowing needs can vary considerably. That’s why it’s important that brokers have a broad range of options available when looking for the right solution for their clients. 

“These latest reductions give brokers more competitively priced options across both two- and five-year fixed rates, while also maintaining a choice of different fee structures to suit different cases. 

“We always review our range closely and make changes where we can. That ensures brokers have both the choice and the flexibility they need when supporting their clients – something we know they expect and value from Keystone.” 

 

TSB ups rates 

TSB has increased residential fixed product transfer rates by up to 0.25% and BTL rates by up to 0.2%. 

On the additional borrowing side, similar increases have been made. 

 

Principality BS increases pricing 

Principality Building Society will withdraw its existing range by 5pm on 23 September to introduce higher-priced options the following day. 

All of its deals at 65%, 75%, 80%, 85% and 90% LTV will rise by 0.1%, except the two-year trackers at 65% LTV, which will go up by 0.15%.
