Understand the commitment before helping someone buy
Thinking of asking someone to support your mortgage, or becoming a guarantor yourself? Count Ready can help you understand the options, the checks involved and what each person could be responsible for.

Your home may be repossessed if you do not keep up repayments on your mortgage. A guarantor may have to repay debt; property or savings provided as security may also be at risk.
In a traditional guarantor arrangement, another person gives the lender a legal promise to meet specified mortgage obligations if the borrower does not. The agreement determines when that promise can be enforced and how much is covered. It is a financial commitment, not a character reference.
Online guides sometimes use “guarantor mortgage” for several kinds of family support. Before comparing offers, establish whether the helper would sign a guarantee, join the mortgage as a borrower, or provide savings or property as additional security.
Giving a guarantee does not itself give someone ownership of the home. Mortgage liability and ownership must be checked separately in the documents.
Check the actual arrangement rather than relying on an old list of lenders. Availability changes, and a lender offering family support may not accept a traditional guarantee.
Its intermediary criteria, checked on 7 September 2026, say guarantor applications have been replaced by joint borrower sole proprietor mortgages. A supporting borrower has different obligations from someone who only signs a guarantee.
Its residential criteria, checked on the same date, list guarantor mortgages as an unacceptable application type while describing Family Assist arrangements separately. The terms are not interchangeable.
These examples explain why terminology matters; they are not recommendations or confirmation that Count Ready can arrange a particular product. Ask us about current routes within our advice scope. We cannot promise that a traditional guarantor mortgage will be available for your circumstances.
Buying together and sharing ownership is another decision. Explain any intended ownership share, repayment or benefit to the adviser and solicitor rather than describing every contribution as a gift.
Expect questions about income, employment, household spending, debts, credit history, deposit and the property. A helper does not remove the buyer’s assessment. There is no universal income multiple or minimum deposit for everything called a guarantor mortgage.
A single applicant or joint applicants should start with a realistic monthly budget. The repayment calculator illustrates payments, not lender approval.
Checks depend on their role. A lender may assess income, credit, existing mortgage commitments, age, residency and any security offered. A retired helper needs to consider pension income and future spending; owning a home alone does not demonstrate affordability.
Check acceptable relationships and UK residence requirements before assuming a parent, sibling, friend or overseas relative can participate.
For self-employed income, discuss the evidence available. If credit is the concern, use our first-time buyer bad-credit guide. Another person’s good credit does not cancel missed payments or defaults on your own record.
Tell us whether the purchase is in England, Scotland, Wales or Northern Ireland. Lender coverage, legal processes and property taxes differ. New builds, shared ownership and other schemes require specific checks; family support does not automatically make them eligible.
Allow for conveyancing, surveys, lender charges, independent legal advice and any broker fees as well as a deposit. Use the existing UK first-time buyer property-tax guide and have your solicitor confirm the transaction.
Ask for the proposed documents and independent legal advice before accepting a commitment. Mortgage advice can explain the available finance; it does not replace a solicitor’s advice on the guarantee or security.
Is responsibility limited to a stated amount, or could it cover the whole debt? Ask whether interest, charges and enforcement costs are included and whether the limit can change.
Ask what triggers a demand, how missed payments will be communicated and how much time you would have to respond. Do not rely on an informal promise that you will never need to pay.
Identify any charge over your property or restrictions on your savings. Ask the solicitor what enforcement could mean for your own home and finances under these particular documents.
Consider your own remortgage, retirement, emergency reserve and other dependants. Disclose the commitment when applying for credit; it may affect what another lender will offer.
The Financial Ombudsman Service’s guidance on being a guarantor highlights financial responsibility and the strain an arrangement can place on relationships. Its general loan guidance is not a substitute for checking the mortgage contract.
You should be free to decline. If you feel under pressure, arrange a private conversation with your legal adviser before proceeding.
Do not assume the commitment ends when the initial mortgage deal ends. The lender may need to reassess the borrower and agree a formal release. Moving home, a higher salary or an improved property value does not automatically remove a guarantee.
Before signing, ask for the release conditions in writing. A later application without support, repayment of the debt or another agreed route may be relevant, but the documents and lender decision control the outcome. Obtain written confirmation that any guarantee and related security have actually been discharged.
If payments become difficult, contact the lender promptly and ask what support is available. A sale may leave a shortfall, so it should not be treated as a guaranteed way to end every liability.
Bring a short outline of the purchase price, location, buyer income, deposit and reason help is needed. The helper should outline their existing commitments and whether they are considering income support, savings or property security.
Our mortgage document checklist covers the buyer’s starting evidence. We can explain what additional information the chosen route needs. Do not send bank statements or identity documents through a general enquiry message; agree a secure route first.
We can discuss the issue you are trying to solve, explain the forms of support and consider suitable mortgage options within the scope of our advice. Ask which lenders or products we can arrange and whether any route requires a direct application. The buyer and helper should each understand their role before moving forward.
The initial consultation is free. Further fees vary by case and are agreed before chargeable work starts. A processing fee may apply separately from an offer fee and is not charged in every case. We may also receive lender commission. Ask for the amount, payment stages and refund terms in writing; read our Terms of Business.
There is no single rule covering every form of family support. Property-backed arrangements require suitable property security, while other routes assess different resources and commitments. Check the actual product and the helper’s role rather than assuming homeownership is always required.
Possibly, but support does not guarantee a larger loan. The lender must accept the arrangement and assess affordability. If another person’s income is needed, a joint borrower sole proprietor mortgage may be the relevant route; it makes that person a borrower, not merely a guarantor.
Ask how the lender checks and reports the specific arrangement, including whether the search is hard or soft. Payment problems can have consequences for your credit. Even if you make no payments, the commitment may affect a future lender’s affordability assessment.
A willing guarantor alone does not establish eligibility for full-price borrowing. Some family-supported products use separate savings or property security, with their own criteria. Buying costs still need funding, and high borrowing leaves less protection if the property value falls.
Notify the lender and ask the solicitor or estate representative to review the agreement. Death does not necessarily cancel the commitment or release security. Do not assume a replacement helper or an insurance payout will be available.
The lender must consider the existing commitments and the proposed support. There is no universal allowance for multiple guarantees. Explain all obligations and consider the impact if more than one borrower needs help at the same time.
Only use the application route the lender specifies for the proposed support. A standard online agreement in principle may not assess it correctly. An AIP remains provisional and does not replace a full mortgage offer or the helper’s legal documents.
You can speak to us while researching, before making an offer or agreeing to support someone. Tell us whether you are the buyer or the potential helper and what you want to understand.
