The new additions, available immediately, include four fixed-rates and three trackers.
Rates start at 5.29 per cent and maximum LTVs across the range are between 70 and 85 per cent.
There are no overhangs on any of the products and each comes with an early repayment charge (ERC) of 6 per cent of the redeeming balance until the product matures on 31 December 2010.
CHL will lend a total aggregate maximum of £1.5 million to individual buy-to-let borrowers, with all bar one of the products requiring 115 per cent rental cover.
Brokers will receive a standard proc fee of 0.5 per cent with no cap and can make full use of CHL's online application system.
Trevor Child, head of sales and marketing at CHL Mortgages, said: “These new fixed and tracker rate buy-to-let products provide a wide range of options for both intermediaries and their clients.
"Coupled with the variety of criteria that CHL offers, the buy-to-let range now delivers real value for landlord and professional investor clients.
"These new products show CHL’s focus on the intermediary market and the buy-to-let sector in particular; they also show our commitment to growing our market share in 2008."
