Answer
There are lenders that can make an allowance for what is known as a builders gifted deposit. in other words, if you buy a new property and the builder will pay 15% of the price as a deposit and as an incentive, as long as the surveyor is happy that it is still worth it. other than that no lenders currently offer 100% buy-to-let. have you considered a remortgage of your own property to release equity to use as a 10% or 15% deposit?
