Doncaster First-Time Buyers: Guarantor Mortgages Weigh Family Risk

First-time buyers in Doncaster can now access guarantor loans that cut the required deposit to as little as 5 percent when a parent or relative pledges their own property as security.

House prices in the DN1 and DN2 postcodes have climbed 4.8 percent since January 2026, pushing the average home to £192,000 and leaving many young workers short of the £15,000 deposit once seen as standard. Local lenders have reported a 22 percent rise in guarantor applications in the past six months, driven by stagnant wages and the end of the government’s Help to Buy equity loan scheme last December.

Doncaster Council’s First Steps register, run from the Civic Office on Waterdale, lists 340 active applicants this quarter, many of them targeting terraced stock on Silver Street and new-build flats at the Lakeside development. The South Yorkshire Property Fund, administered from the same office, offers an additional £3,000 grant for buyers who complete before March 2027, but only if they use an approved guarantor product from one of the five lenders currently operating in the borough.

Pros and cons for local buyers

A guarantor loan lets a buyer borrow up to 95 percent of the purchase price, which in practice means a £192,000 house on Silver Street requires only £9,600 from the purchaser instead of £38,400. Interest rates on these products currently sit at 4.89 percent fixed for two years, 0.35 percentage points above standard 75 percent loans. The main drawback remains the guarantor’s exposure: if payments are missed, the lender can pursue the guarantor’s home, a risk that has already led two Doncaster families this year to remortgage their own properties after their children fell behind.

Eligibility rules are strict. Applicants must be first-time buyers with a household income below £60,000, hold a permanent contract of at least 16 hours a week, and pass an affordability test that assumes the Bank of England base rate rises to 6 percent. The guarantor must own a property with at least 25 percent equity and be under 70 years old at the end of the loan term. Credit scores for both parties are checked, and any outstanding council tax arrears in Doncaster automatically disqualify the application.

Next steps for those who qualify

Prospective buyers should book a free appointment with the council’s housing team before 31 July to confirm they appear on the First Steps register and to receive a list of solicitors who specialise in guarantor deeds. Lenders require a valuation within 90 days of the offer, so anyone targeting a property on Hexthorpe Road or at the ongoing Lakeside phase should instruct a surveyor now. Early contact with the lender also reveals whether the chosen guarantor’s equity meets the 25 percent threshold before any paperwork is submitted.
