Landlords can choose from 41 buy-to-let deals at a record low of 1.5% or below, according to analysis by Property Master.

The Mortgage Works is offering the lowest rate at just 1% for a one-year fixed rate up to 65% LTV, however the deal is only available to existing customers as a product transfer.

For those looking to purchase a property, TMW is offering a two-year fixed rate of 1.19% up to 65% LTV with a 2% fee.

Other lenders offering deals for less than 1.5% include Santander, BM Solutions and HSBC.

Property Master chief executive Angus Stewart says: “With the housing market racing to the finishing line of the stamp duty holiday and with rents on the rise in most regions many landlords are looking to increase their property portfolio.  

“Unsurprisingly lenders in the buy-to-let mortgage market are keen for a slice of this business and competition is hotting up in terms of pricing and the variety of products on offer.

“Our advice to landlords though is to always look beyond the headline grabbing price.  

“Lenders are still keen to manage their risks and some of the better deals come with lower LTVs of 60 or 65%.  

“Other lenders are limiting their offers to remortgages or product transfers.  But this is not always the case and there are definitely some bargains to be had. 

“Some lenders are not willing to lend to first-time landlords or those that are not a homeowner.  

“If you are looking for a buy-to-let mortgage for an HMO or for a holiday let, then you may find yourself looking for a more specialist lender but here too there are some competitive deals.  

“Our technology which is based on the extensive use of algorithms brings together in one search pricing as well as product, lending and affordability criteria in this increasingly complex marketplace.”
