Lender's fees & legal costs (arrangement fee + lender's solicitor)

Don't forget: on development finance you almost always pay the lender's legal costs and arrangement fees as well as your own conveyancing. It is one of the most commonly forgotten costs in an appraisal, so make sure it is captured in the field above.

Important. This model is provided by Hussnan Strategic Advisory for illustration and general information only. It is not financial, investment, tax, valuation, or development advice, and figures are estimates based on the assumptions you enter. Finance is modelled from the facilities you enter: the land loan is drawn at the start and financed for the term, and the construction facility is drawn down in equal monthly amounts, with interest charged monthly on the outstanding balance and rolled up (compounded), so the debt grows as a curve. Only the borrowed amounts accrue interest; any equity you contribute does not. Drawdown is assumed straight-line rather than an S-curve, over a single blended period rather than separate build and sales phases, so this remains an approximation and does not replace a lender's detailed cashflow. SDLT on land is calculated on the basis you select — non-residential / mixed-use, or residential at additional-property / company rates — for England & Northern Ireland; Welsh (LTT), Scottish (LBTT), first-time-buyer relief, VAT, CIL/S106, and company/SPV specifics are not modelled. All figures are pre-tax. Always commission a full appraisal and take regulated professional advice before acquiring a site.
