Two schemes on the table — how the choice plays out.
Picture a single buyer on a steady income with a small deposit saved, who's heard about Help to Buy and assumes it's the obvious choice — but isn't sure whether to use it or the 5% Deposit Scheme, and doesn't realise you generally can't use both.
This is where a broker earns their keep: laying the two paths side by side. With Help to Buy they'd borrow far less and have smaller repayments, but give up a slice of future growth; with the 5% scheme they'd keep 100% of the upside but carry a larger loan. The income limits and the price cap for the area both get checked before anything else.
If smaller repayments matter more to this buyer than maximising future growth, Help to Buy may win out — and the next step is a lender that accepts the scheme through brokers. The point isn't which scheme is "best" in the abstract; it's matching the mechanics to the buyer in front of you.
