What happens to the Help to Buy arrangement if the property market moves significantly after purchase and does an increase or decrease in property value change the government's equity share in a way that affects future decisions about the property?
The government's equity stake in a Help to Buy property is expressed as a percentage rather than a fixed dollar amount which means the value of what's owed back on sale or buyout moves with the property's value. Whether that creates a situation where strong capital growth produces a significantly larger obligation to the government than the original contribution represented, how a market downturn affects the arrangement and whether there are scenarios where the equity share creates a practical constraint on decisions about the property are all questions that seem worth understanding clearly before committing to the scheme. Would love to know how people here who've thought about the long term mechanics have processed that uncertainty.
