How much of a deposit to put down on first house.

[AdviceHunter]

In parallel to another recent post, I just want to run my logic by the PH Finance crowd to see if my reasoning makes sense, or if I’m missing something fundamental.

I am around 30 years old and have always rented due to being mobile with work, in UK and overseas. In a few months’ time, I will have accrued approximately £100,000 which I intend to put towards my first house, ideally a ‘keeper’. I anticipate the value of the house will be around £250,000 (four bed, nice area, up north). I earn a relatively steady wage and don’t see this changing, at least £40,000 in the North of England. I also have the option to earn more overseas if required.

I always wanted to have a small a mortgage as possible if circumstance allowed and have always been risk averse in terms of credit, loans and the like.

So, the question is, does my life long belief of putting down as much as possible make sense (ie. the full £100,000, with a bit aside for a rainy day) or do I just go for the ‘enough to get a good rate’ (ie. £62,500, or 25%) and invest the remainder elsewhere?

I have researched online, and often see 'above 25% for the best mortgage deals' mentioned, but very little information regarding higher deposits.

Just looking for advice on how others would handle similar circumstances.

Cheers.
