Buy To Let vs Index Funds — Which Made More Money Over 25 Years? (Real UK Data)

In this 25‑minute YouTube monologue Dr. Ndubuisi “Andy” Egwim (MoneywiseDoctor.com) compares two investment pathways for a UK doctor who has £10,000 to invest in January 2001. He builds a side‑by‑side model using real UK data – house‑price trends from HM Land Registry, historic mortgage rates, rental‑income bands, letting‑agent fees, maintenance costs, and the tax regime (pre‑ and post‑Section 24, income‑tax rates, and capital‑gains‑tax (CGT) rules). The two fictional investors are Dr. Bayo (a surgeon) who buys a £100k buy‑to‑let (BTL) with a 10% deposit and a 5.8% 25‑year repayment mortgage, and Dr. Gloria (a GP) who puts the same £10k into a globally diversified MSCI World index fund inside a Stocks & Shares ISA, contributing the same £569.25 each month. The analysis details Bayo’s gross rental income (£235,200), costs (letting‑agent 10%, maintenance 1%/yr, mortgage interest £85,705), and tax (Section 24 limiting mortgage‑interest relief, resulting in £34,690 income‑tax). Net rental profit after 25 years is £132,140, and after selling the property he faces a £56,145 CGT bill, leaving a net wealth of roughly £315k. Gloria’s ISA, after a blended TER of 0.22% and an 8.28% net annual return, grows to about £640k tax‑free, with zero exit tax. The net wealth gap is £325k. Egwim then introduces the REST decision framework (Real return vs risk, Effort, Stress, Time) to evaluate any investment, and recommends doctors first secure a primary residence, maximise pension and ISA contributions, and only consider BTL after passing the REST filter. The video ends with calls to action for a free MedScan health‑score, a free investing masterclass, and subscription prompts.
