Irish Buying in Scotland for PPR

Hi,
My Brother has reciently moved from London to Edinburgh in Scotland and is looking to buy an apartment to live in with his girlfriend.

They have about £70K for a deposit and are looking at apts for sale at around £200K.

Can anyone direct me/them? They are calling in to brokers etc but are geting conflicting views as they have not secured full time work yet.
Can anyone fill in some basic buyer questions?

• What stamp is to be paid at £200K
• What other transaction costs should they expect to pay
• can they get a mortgage based on the properties rental ability alone? (as you can in England as an investor mortgage)
• any tips/ refferals?

Thanks,
Ixer

There is a website mentioned in this thread (Singingpig) that might be a more appropriate place to ask these questions.
