Important information

Important information about your shared ownership estimate

Please review the assumptions and limitations below before relying on the results from this shared ownership calculator.

Confirm all costs with the housing provider

Rent, service charges, management fees and other property costs vary between homes and providers and may change over time. Check the provider’s key information document, lease and current charges before making a financial commitment.

The calculator assumes that:

  • The full market value and percentage share entered are accurate.
  • The mortgage is a capital-and-interest repayment mortgage.
  • The illustrative mortgage rate and term remain unchanged.
  • The rent percentage is applied to the value of the unsold share.
  • Service charges and other housing costs remain at the amounts entered.
  • Any mortgage product fee added to the loan is included in the illustrative mortgage balance and payment.

What the estimate does not include

Results do not include every possible cost, such as reservation fees, legal fees, valuation fees, moving costs, insurance, repairs or future increases in rent and service charges.

The calculator does not confirm that you meet a shared ownership scheme’s eligibility rules or that a housing provider or mortgage lender will approve your application.

Restrictions may apply when selling, subletting or purchasing further shares through staircasing. These will depend on the scheme and lease.

This calculator provides an illustrative estimate only and does not constitute mortgage, legal or financial advice or confirm scheme eligibility.
