Let's talk loan to value ratio, in 20.
If you have a £20,000
deposit on a £200,000 house,
you're paying 10% of the value,
and need to borrow £180,000.
Which means your loan to value ratio
is 90%.
Lenders like a lower
loan to value ratio,
and could give you
a better interest rate.
So the bigger your deposit, the better,
which is something worth bearing in mind.
