Finance
Funding self build projects has become much easier over the last decade or so. Financial institutions have tailored their products to help with self build especially around making stage payments as the building progresses. This includes buying the land in the first place.
This now means that once your mortgage is approved you can draw down finance, usually in four stages. It is normal for the lender to insist that each stage is checked by a registered surveyor before the money is released and it is your responsibility to pay the surveyor.
Most lenders will want to see drawings of your proposed house and evidence that you have obtained planning permission.
Although it depends on the exact mortgage package you get, you will normally need to find the finance to carry you through until the first stage payment is received.
