How Do Self Build And Custom Build Mortgages Work ?

  • The main difference between self build mortgages and custom build mortgages over a traditional mortgage is that the money is released in stages as the build moves forward, rather than as a single amount.

  • Typically 20% cash deposit is needed against the cost of the whole project (purchase of land & build costs). However there are lenders that will allow a lower deposit and we can fund projects with a deposit as low as 15% of the overall cost.

  • Funds can be released in advance or in arrears of each build stage. The cash flow of your project will dictate our recommendation to you.

  • Use our on-line calculators to find out how much you could borrow and how much your build would cost.

  • You only pay for funds that are live.

  • Most lenders will allow a product transfer to their standard mortgage range, post build and waive any early redemptions penalties. Some have no ties in at all and some are more restrictive.

  • All construction finance mortgage lenders will want to see a fully itemised and costed build including a contingency. The contingency requirement can vary from 10% to 20%. We’d recommend using the 20% contingency

  • Lenders will release funds for clients to buy land, subject to the plot having a minimum of outline planning or permitted development rights.

  • Those who already own land and have detailed planning agreed could release up to 100% of the build costs.

  • Stages of funds being released can vary slightly from project to project depending on the lender and the construction mechanism you are using.

  • lenders agree the full facility required at the out set and release funds as the build moves forward.

  • Most lender will allow an interest only concession during the build period to help keep cost down

  • Any self build lender will want to see that all the project financials are covered on paper to take the project to practical build completion . This means that the loan and or any savings must cover the purchase price of the plot and build cost including a contingency.

Why Is It More Difficult To Get A Self Or Custom Build Mortgage

  • There are less lenders available for you then if you were buying a completed property. Currently none of the top high street banks fund self or custom build.

  • Of the lenders available each will want a detailed cost report including contingencies. Each lender has a different contingency requirement and may even have a minimum build cost they will lend against.

  • Even though all the self build lenders will agree your full facility at the outset they will release your funds in phases. As part of any application, they will want to see a cashflow forecast to ensure that the way their product releases monies will fit the requirements for your builds cashflow needs. If it doesn’t, they won’t fund.

  • The lender will need to know the details of the proposed development including the super structure, how the outer skin is attached, what it is and what certifications each element has. Every lender has differences in their criteria and nuances as what is and isn’t accepted.

  • Your lender will need to know what level of involvement you intend to take and who will be involved in the build. Some lenders are completely happy for you to lay every brick, others are not and this will depend on the development you have planned and you own circumstances.

  • Self Build lenders will require specific build insurances such a warranty and site insurance. Certain lenders accept some providers and not others and can different levels of requirements needed for the site insurnace.
