How Are Self-Build Mortgages Calculated

Self-build mortgages can be ideal for borrowers with the means and expertise to build their own homes or oversee their development, but how are they calculated?

Because everyone is different, it’s difficult for a mortgage calculator to take into account all the factors these products involve. The good news is that the self-build mortgage advisors we work with are experts and can provide a clearer picture of how much you can borrow and what your repayments are likely to be.

Calculators can provide a rough guide, so we’ve put together this article on how self build mortgage calculators can be used by both prospective customers and UK lenders, which covers:

How are self-build mortgages calculated?

For anyone considering self-build mortgages for a property in the UK, the key piece of information needed from any type of calculator tool indicates how much you may be able to borrow and an approximate monthly repayment.

Most traditional calculators simply require a purchase price, deposit size, mortgage term, and interest rate to offer an indication of how much you can borrow and what it could cost.

Will a self-build mortgage calculator tell me how much I can borrow?

Not definitively. Mortgage borrowing for self-build projects involves a great deal more thought and planning before you can confidently type into a calculator how much lending you feel you will need.

Things to consider would be:

• The size of the building plot required and an estimate of the cost
• Size of property you want to build
• Type of building materials you want to use (bricks and mortar, timber frame, etc)
• Cost of internal decoration and design
• Cost of external landscaping
• Is it a self-managed project or a contractor?

The planning stage can feel daunting (particularly if it’s your first time). This is where we can help. The advisors we work with have years of experience with self-build mortgages and will have a deep understanding of what information you will need to plan your project.

If you make an enquiry, we can arrange for an expert to contact you directly and discuss this further.

Where can I find a reliable self-build mortgage calculator?

Self-build mortgage calculators are tools used by lenders and advisors to give an initial indication of what borrowers may be able to borrow for this type of lending.

Such tools can also be found on mortgage lenders’ websites and other financial hubs – but keep in mind that online calculators will only give you a rough idea of the amount you’d be able to borrow and how much your repayments will be.

If you’d like to discuss which self-build finance options best suit your circumstances, make an enquiry, and we can arrange for an advisor we work with to contact you.

Do all UK lenders use their own self-build mortgage calculators?

Yes, it’s quite typical for most UK lenders to have online calculator tools for their suite of mortgage products and for these to be available for you to use.

Bear in mind a self-build mortgage calculator on a lender’s website will usually be programmed in line with that provider’s in-house affordability criteria. Each lender’s criteria will vary, which may produce different results based on the information you provide.

How reliable are self-build mortgage calculators?

Online calculator tools are used for indication purposes only. Each lender follows their own internal eligibility criteria before reaching a final decision on what they would be prepared to lend a customer. All of these factors may affect how much you can borrow.

These criteria include:

• Affordability assessment (review of income and outgoings)
• Age of applicant(s)
• Applicant’s existing lending commitments
• Applicant’s credit history
• The size of the mortgage required
• Size of deposit
• Mortgage term required
• Type of property (in this case, what type you are looking to build)
• Experience in property

This is where we can help. The advisors we work with adopt a ‘whole of market’ approach and, therefore, can identify which lenders offer the most favourable terms for self-build mortgages. If you make an enquiry, we can arrange for an expert to contact you.
