And from what you have written here, you most certainly do have some doubts about the decision you would like to make.

I didn't say I don't have doubts, I said I am not scared. Massive difference. Doubts drive for due diligence to be done, like an investor knowing what they are investing themselves into and what the conditions and risks are .

This will be the 4th property I will be buying, the first when I was 18 and a student. I am not scared from experience as I lost my first house due to costs associated with my mother's death from cancer just after I moved to the other side of the world. The financial recovery took a few years time before I could buy again and renovate, then I sold that for a profit so to buy again and renovate and we will sell this for a profit too.

Doubts are good. Doesn't mean they should freeze you in fear.
