Phil Coombes, head of intermediary sales at Leeds, said: “Our new 5-year buy-to-let product will attract professional landlords, who may wish to move onto a highly competitive rate and fix their monthly commitments.
“The society is also benefiting first-time landlords who may require help with upfront costs by offering a market leading fees assisted deal for a 5 year period.”
