What this models

  • Buy net position: property equity minus all cash outlays (deposit + stamp duty + legal fees + all mortgage payments + annual maintenance).
  • Rent net position:what the buyer’s upfront costs would grow to if invested at the stated return rate, minus total rent paid.
  • Stamp duty uses Irish residential rates: 1% on the first €1m, 2% above.
  • Central Bank LTV rules: 10% minimum deposit for first-time buyers, 20% for subsequent buyers. LTI limit of 4× gross income is not modelled here.
  • Does not model: mortgage interest relief, Help to Buy, rent tax credit, property taxes (LPT), agent fees on sale, or rental income.
