Leasehold vs Freehold: Financial Implications Deep Dive

Two properties, same area, but one comes with a lease clock and a service charge ticking against you. Give both prices, the lease years remaining, the service charge and your ownership horizon, and you get a deep cost comparison over time: mortgage, charges, lease-extension risk and total ownership cost. For buyers choosing between tenures with their eyes open.

I'm comparing two properties: a leasehold flat at {LEASEHOLD_PRICE} with {LEASE_YEARS_REMAINING} years remaining and a service charge of {ANNUAL_SERVICE_CHARGE}, and a freehold house at {FREEHOLD_PRICE}. Both are in the same area.

Provide an advanced financial comparison of the two tenure types. Model the true total cost of ownership over {OWNERSHIP_HORIZON_YEARS} years including: mortgage payments, service charges and ground rent (leasehold), maintenance reserves (freehold), and the cost and process of lease extension if the leasehold drops below 80 years during ownership. Quantify the leasehold discount I should demand to be financially indifferent between the two, and flag any post-Leasehold Reform Act 2024 provisions that affect my decision.
