Self Build Mortgages - The basics explained

In a self build mortgage the lender advances funds in stages as works are completed allowing you to move onto the next stage of the build process up to completion of the build.

Some lenders may be able to advance money to assist in land purchase and others may only advance any funds once a certain stage of work has been completed.

Funding will likely be based on your income and affordability like a normal mortgage.

The lender will usually assess the work at each stage of the build including checking relevant approvals and sign off including planning approval, structural engineer's certification & building regulations compliance.

Once work is completed you can usually stay on the mortgage long term like any normal mortgage deal or remortgage to a new deal from the normal high street although early repayment penalties might apply to some products for a few years.

You will normally need slightly larger deposits for self build loans, lending against income is likely to be lower than a normal mortgage (although the likely cost of the property should also be quite low).

Some features may be available which would be unusual on a normal residential loan such as having interest only payments until the final completion of works.

Self Build Mortgages - The detail

Some self build mortgages are only for the purpose of building an entirely new property however many of the products available now are suitable for property renovation and work in much the same way.

It’s also typical for many lenders offering self build loans to require that you begin the application process prior to completing any work.

So it’s not preferable to only begin researching a mortgage once a project has started although if you have found yourself in this position we may still be able to help you but it’s likely less options are available.

Most lenders can advance funds in various stages, at each point checking the completed works and advancing more money to complete the next stage.

This will usually involve a surveyor coming out to inspect the site and seeing sign off from architects, engineers or building control officers as applicable.

It’s therefore vital not only that the work meets applicable standards and appropriate approvals are provided and that you do not overspend and find yourself in a position where you cannot complete a stage of works.

Many advance funds at the end of each stage of the works, however some can advance funds prior to each stage.

This will be crucial for some, for example if you only have funds to buy the land, you will need funding in advance to complete the foundations.

The stages at which a lender can advance funds are also important.

Some lenders can advance funds through each stage of the build from as early on as buying the plot of land (or even being gifted/inheriting it), and will continue to advance funds through the various stages.

These include stages such as the foundations being laid, walls erected up to second storey level, wind & watertight, first fix and final completion (but various lenders will differ on exact points).

Other lenders particularly some of the more national high street lenders may only advance funds much further into the completion of the project and hence you will need considerably more cash aside at the outset to use these lenders.

Most of the lenders offering these products will also be small building societies and hence the lending rules will generally be more restrictive than a normal mortgage and hence advice will make finding a suitable deal considerably easier.

You will probably find a considerable number of the products offered are also discount or variable rates particularly for those with more flexible or generous options around stage and advancing funds upfront.
