FAQ: New Build Developments Under £300,000 in London

With a 95% mortgage, a 5% deposit requires £15,000, while a 10% deposit requires £30,000. Several developers active in this price band offer deposit contribution packages (such as 5% developer-paid deposits) or participate in the Own New Rate Reducer scheme to lower initial payments.
Yes. Shared Ownership developments enable buyers to purchase an initial equity share (typically between 25% and 50%) of a newly built property, significantly reducing the initial deposit barrier while allowing future staircasing up to 100% ownership.
