You say that, but a starter home in Brighton is no less than £270k, which is already a 27k deposit to get any form of decent interest rate on a mortgage. When you then add a further 3k on the stamp duty, it starts getting a little ridiculous about what is to be expected. Unfortunately due to family caring issues, we need to be within Brighton. Personally, I'd rather they just switched Stamp Duty to the seller, then it's only really affecting people at the end of life compared to what there is now.
It's all well and good them increasing the supply, but that will take years, when there is a need for something to happen much sooner than that.
