How to interpret the result
A loan payment, gross yield or purchase budget describes only part of ownership. Read exclusions carefully: affordability, lender approval, vacancy, repairs and transaction eligibility may not be fully modelled.
Compare like-for-like properties or financing scenarios, with the same term and cost basis. Where relevant, test a higher interest rate, a vacancy period or a larger maintenance allowance.
Common mistakes to avoid
- Do not compare gross rental yield with net cash flow as if they were the same measure.
- Do not assume a favourable tax result means the property or letting qualifies for a scheme.
- Keep refundable deposits and recurring costs separate from permanent acquisition costs.
