100% and No-Deposit Mortgages can solve the hardest part of buying a first home: raising a deposit while rent and everyday costs continue. The buyer still needs a credible budget, acceptable credit and cash for moving costs.
For first-time buyers with reliable income and a strong rental record, a no-deposit route can bring ownership forward. It should still be compared with a 95% mortgage and family support.
Yes — what are 100% and No-Deposit Mortgages?
Yes, 100% and No-Deposit Mortgages allow an eligible buyer to borrow the full accepted value of a property without contributing a conventional cash deposit. The loan-to-value ratio, usually shortened to LTV, is therefore 100% at completion.
In professional terms, “no deposit” describes the purchase contribution rather than the entire buying budget. MoneyHelper’s guide to 100% mortgages confirms that buyers can still face solicitor, search, survey, moving and mortgage-related costs.
No — does no deposit mean no savings are needed?
No, a buyer should not approach a no-deposit purchase with no savings at all. Legal work, searches, a survey, removals, insurance and repairs can all require cash.
Three reserves matter: money for the transaction, unexpected property costs and an interruption to income. A mortgage that consumes the monthly surplus can be fragile.
For a first-time buyer in England or Northern Ireland, Stamp Duty Land Tax may also apply. Current First-Time Buyers’ Relief provides 0% on the first £300,000 and 5% on the portion from £300,001 to £500,000, provided the conditions are met.
Rental history can help — who might qualify?
Rental history can support an application where a lender offers a product for proven renters. It does not replace affordability assessment, credit checks, property criteria or income verification.
A current example is Skipton Building Society’s Track Record mortgage. Its published criteria include being aged 21 or over, having no missed debt or credit payments in the previous six months, borrowing no more than £600,000 and showing 12 consecutive months of rent paid within the previous 18 months.
Could a buyer qualify without a guarantor? Yes, some renter-based 100% and No-Deposit Mortgages do not require family security, while other structures rely on a guarantor, a relative’s savings or equity in another property. Meeting headline criteria never guarantees an offer.
Affordability still decides the loan — how much can be borrowed?
Affordability still decides the maximum loan because rent history is only one part of the evidence. Income, regular spending, credit commitments, childcare, student loan deductions, maintenance and the proposed term can all affect the result.
The FCA’s responsible-lending rules require a regulated lender to assess whether the borrower, and any guarantor where relevant, can pay the sums due. The property value alone cannot justify approval.
FCA data for the first quarter of 2026 show that only 0.5% of gross mortgage advances had an LTV above 95%. This shows that such lending remains a small part of the market.
For a buyer already paying high rent, the mortgage payment may look manageable. The comparison should also include service charges, buildings insurance, maintenance and any increase after the initial deal ends.
Negative equity is the central risk — what does it mean?
Negative equity is the central risk because the mortgage starts at or near the property’s full value. If the home falls in value faster than capital is repaid, the outstanding loan can become larger than the amount the property could sell for.
A £250,000 purchase followed by a fall in value to £240,000 creates an immediate gap before selling costs are even factored in. This is negative equity — owing more on the mortgage than the property is currently worth. It doesn’t affect monthly repayments if the borrower stays put and keeps paying as normal, but it becomes a real problem the moment they need to sell, remortgage, or move: the mortgage balance can exceed what the sale would raise, leaving a shortfall to cover from savings or, in some cases, preventing the move altogether until values recover or the balance is paid down.
Uncomfortable as it sounds, the problem becomes most serious when the owner needs to sell or remortgage early. Time can help reduce the balance, but no future value is guaranteed.
Valuation risk also matters before completion. If the lender values the property below the agreed price, the buyer may need cash to cover the difference, renegotiate the price or leave the transaction.
A small deposit can improve the options — is waiting worthwhile?
A small deposit can improve the options because reducing the LTV normally widens the product range. It can also reduce borrowing and monthly payments.
For some renters, waiting remains the weaker decision if rent and personal circumstances make saving painfully slow. For others, another six or twelve months could create a 5% deposit, stronger reserves and a more competitive choice.
Numbers, timing and resilience should settle the decision. A comparison should test the no-deposit mortgage against a likely 95% mortgage, including fees, monthly payments, early repayment charges and the cash remaining after completion.
Family support can create alternatives — what structures exist?
Family support can create alternatives without always giving the buyer a permanent cash deposit. Some mortgages allow a relative to place savings into a linked account or provide property as security, while others use a guarantor who becomes responsible if the borrower cannot pay.
A serious legal and financial obligation sits behind these arrangements. A guarantor may face affordability checks, while secured family savings may be inaccessible for an agreed period.
For families able to provide money permanently, a gifted deposit may open a wider selection of lower-LTV mortgages. Oakstead Finance’s gifted deposit guide explains common evidence requirements, while the guarantor mortgage guide covers family-backed responsibilities.
Another route is a joint borrower sole proprietor structure, where a supporting person may join the mortgage without becoming an owner. Oakstead Finance’s JBSP mortgage guide explains the structure, but legal and tax treatment must be checked.
Preparation improves the application — what should be checked first?
Preparation improves the application by exposing problems before a property is chosen. The buyer should establish the likely borrowing range, review credit files, confirm rental evidence and calculate the full cash requirement before making an offer.
Bank statements, payslips or self-employed income evidence, identification, proof of address and rental records may all be needed. The exact list varies by lender.
For a renter-based product, rent paid from an identifiable bank account is easier to evidence than cash or transfers with unclear references. A letting-agent letter may be accepted by some lenders, but the published criteria should be checked.
Finally, a mortgage valuation is not a detailed condition survey for the buyer. A separate survey should be considered, particularly when 100% and No-Deposit Mortgages leave little spare cash for major repairs.
In Summary
100% and No-Deposit Mortgages provide a real route for buyers who can afford ownership but have struggled to build a deposit. They remain subject to affordability, credit and property checks, and the product range is much smaller than the market for mortgages with a deposit.
Risk, cost and flexibility need to be assessed together. Buying sooner may be rational where the budget remains resilient, the property is sensibly priced and the buyer understands negative equity.
Frequently Asked Questions
Can a first-time buyer get a mortgage with no deposit?
Yes, a small number of lenders offer 100% mortgages to eligible first-time buyers. Full affordability, credit and property checks still apply.
Does a 100% mortgage require a guarantor?
No, not every 100% mortgage requires a guarantor. Some use evidence of reliable rent payments, while others require family savings, property or a guarantee.
Is rent payment history enough to get approved?
No, rental history can support the case but does not replace full underwriting. The lender will also assess income, expenditure, credit conduct and the property.
Are 100% mortgages more expensive than 95% mortgages?
They can be more expensive because the lender advances a larger share of the property value. The comparison should include rates, fees, monthly payments and early repayment charges.
Can a buyer use savings with a no-deposit mortgage?
Yes, savings can normally be retained as a reserve or used where the product permits a small deposit. An emergency fund can protect the buyer after completion.
What happens if the property is valued below the agreed price?
The lender may calculate its advance from the lower valuation. The buyer may need to renegotiate, provide cash for the shortfall or withdraw before becoming legally committed.
Can a no-deposit buyer claim First-Time Buyers’ Relief?
Yes, deposit size does not determine eligibility. The buyers, property value, intended occupation and statutory conditions determine whether the relief applies.
Can a Lifetime ISA help instead of a 100% mortgage?
Yes, a Lifetime ISA can help an eligible first-time buyer build a deposit through a government bonus. A qualifying withdrawal generally requires a property costing no more than £450,000 and an account open for at least 12 months.
Should a first-time buyer wait and save a 5% deposit?
Waiting may provide more options, lower borrowing and stronger protection from negative equity. Buying sooner can still be reasonable where the product is affordable and reserves remain available.
100% and No-Deposit Mortgages should be treated as a funding solution, not permission to buy at the edge of affordability. Oakstead Finance can compare the available routes and test the full cost before a first-time buyer commits.
