  • Loan term 12 months

The Castle Trust Refurb to Let product is perfect for landlords who want to maximise rental value and increase capital growth by upgrading their property. This can include a new kitchen, bathroom, redecoration, re-wiring, or any other light refurbishment that doesn’t require building regulations or planning permission.

The loan term on Castle Trust’s Refurb to Let product is 12 months and interest is rolled up over the term for payment on redemption of the loan.

What Do Castle Trust Offer For Development Finance?


Castle Trust specialises in heavy refurbishments and ground up developments. The heavy refurbs refer to things like turning a house into flats, developing a block of houses or flats, renovating a commercial property such as an office or store. With their loans starting at £2 million and lasting for around 24 months, it needs to be a substantial refurbishment. The ground developments can be a basic plot of land which is completely empty and building this up into a house, flats or commercial building.

The firm offers a Gross Development Value of up to 70% which is higher than some of its competitors. This is the potential value of the development once it has been fully completed and will be sold on the open market. It incorporates things like land and construction costs and the eventual value of the estate.

Their website explains that all loans are taken out by way of first charge. This is the first priority when it comes to making any mortgage repayments and since there are no other priorities in its way, it usually maximises the amount you can borrow and the minimises the deposit you need to put down. Customers are expected to put their equity down from day one – so you are required to deposit at least 30% of the value of the development when your loan is funded.

The interest rate charges is fixed, so it will not change during the loan term. The interest is calculated daily and compounded monthly. It can be rolled up into the redemption of the loan, so you can repay when you intend to exit the development property such as a sale of the project.

What Do Castle Trust Offer For Mezzanine Finance?


Castle Trust refer to this as ‘Mezz Finance’ and the idea is that for riskier projects, customers are able to borrow more but will need to give away some more equity. For the lender, like Castle Trust, they are able to lend more and by taking on more risk, able to maximise their return on investment.

Their website explains:

Mezz is subordinated debt, typically second charge, ranking behind the senior debt. Mezz is normally deployed ahead of senior and gets repaid after the senior is redeemed.

Due to the complex nature of mezzanine finance, the company review each one on a case-by-case basis, typically offering finance on the following:

  • New builds
  • Land with planning permission
  • Heavy refurbishment / extensions
  • Commercial to residential conversions
  • Purpose built student accommodation
