Most agents use reputable builders who will issue a bank guarantee to protect the payments you make during the build process. All builders will have their own staged payment structure so can differ from builder to builder. Inspect properties that are key ready. A builder’s guarantee is issued and snagging lists are addressed. It is advisable to buy through your agent as they can act on your behalf and normally can get the support of their preferred legal team to assist if required. During the build, your agent can provide photographic evidence of the build project when required, prior to the next stage payments.
