The changes apply to all fixed and tracker deals at all loan to value levels.
The cut follows reductions of up to 0.30% on selected products on 8 February.
BM Solutions will also launch new fixed rate products at 75% LTV with two product fee options at £995 and 0.50%.
Following the changes BM Solutions will offer options at four different fee points in the 2-year fixed market at 75%.
Phil Rickards, head of sales BM Solutions, said: “This is our second round of price reductions in as many weeks. By launching some new deals and reducing all rates in the current range, we're really shaking up competition in the buy-to-let market.”
BM Solutions has emailed brokers this afternoon to inform them that any applications on the current rates need to be submitted by 8pm this evening.
