Housing tax and legal structures for a family replacement home

Independent background research on a retired father contributing about £270,000 of compulsory-purchase proceeds into a roughly £500,000 England home where his daughter takes the mortgage and all three family members live together.

Purchase price model: £500,000 Daughter: first-time buyer, no other property Parents: selling only or main home, no other property Not regulated legal, tax, mortgage, or care-fees advice

Scope and disclaimer

This page is background research for discussion with a conveyancing solicitor, tax adviser, and whole-of-market mortgage broker. It is not legal advice, tax advice, mortgage advice, financial advice, or care-fees planning advice. The family facts and lender criteria matter enough that documents should not be signed from this analysis alone.

The analysis assumes England, UK-resident individual buyers, a freehold or ordinary leasehold residential purchase at exactly £500,000, no other properties owned after the parents sell their current main residence, and no unusual trust, company, overseas, non-resident, divorce, benefits, bankruptcy, or mental-capacity issues.

Bottom Line

Best legal-protection structure

The cleanest way to protect the parents' capital and occupation is usually co-ownership as tenants in common, backed by a declaration of trust, Form A restriction, wills, and a carefully drafted occupation/life-interest arrangement. It costs about £5,000 more SDLT than sole first-time-buyer ownership at £500,000, but it is much more honest about who is economically buying the home.

The practical problem is the mortgage: many lenders expect all legal owners to be borrowers, and retired co-owners may not fit affordability or age criteria. A broker must test this before solicitors draft around it.

Best tax/lender fallback to explore

If the daughter must be sole owner and sole borrower, the strongest alternative is normally a documented no-interest family loan, not an outright gift. HMRC says an interest-free loan repayable on demand is not itself a gift with reservation, and the POAT land contribution rule does not apply where the occupier lent the money because the debt remains in the lender's estate.

That route keeps first-time-buyer SDLT relief, but the lender may treat the loan as a liability or reject it. It also protects money less well than ownership, because any right to occupy or be repaid will usually be postponed to the mortgage lender.

Concrete Numbers at £500,000

£10,000 SDLT if the daughter alone buys and qualifies for first-time-buyer relief: 0% on £300,000 and 5% on £200,000.
£15,000 Normal residential SDLT if parents are purchasers or beneficial co-owners: £2,500 on £125k-£250k, plus £12,500 on £250k-£500k.
£40,000 Illustrative SDLT if the additional-property 5% surcharge applied and was not refunded. It should not apply if the parents replace their only main residence on time.
At exactly £500,000, first-time-buyer relief saves £5,000. At £500,001, the relief is unavailable and the SDLT is effectively normal residential SDLT.
Scenario Who is treated as buyer? Likely SDLT at £500k Comment
Daughter sole legal and beneficial owner; father gives cash Daughter only £10,000 FTB relief can work, but father has no protected capital/right unless separate documents exist, and lender gifted-deposit rules are difficult if he will live there.
Daughter sole owner; father lends cash Daughter only £10,000 Best SDLT result, but the loan may reduce affordability or be unacceptable. It needs a real loan agreement and lender disclosure.
Parents and daughter on title as tenants in common All co-owners £15,000 No FTB relief because all purchasers must be first-time buyers. Usually better for capital protection.
Daughter sole title but declaration of trust gives parents beneficial shares Beneficial owners are looked through for SDLT Probably £15,000 A bare trust is generally transparent for SDLT, so this should not be assumed to preserve FTB relief.
Discretionary or life-interest trust buys Trustees or life tenant depending on trust Specialist calculation Likely over-complicated for this family purchase. Can trigger trust SDLT/IHT/POAT issues and major lender friction.

Main Structures Compared

Structure Legal effect Tax treatment Parent protection Main blocker
Outright gift Father gives cash to daughter. Daughter owns the home outright unless a separate beneficial interest is created. Potentially exempt transfer for IHT if no reservation; but occupation creates POAT/GWR analysis. FTB SDLT can be £10k only if daughter is sole beneficial buyer. Weak Father cannot demand repayment and has no automatic right to stay. Gifted-deposit forms usually require no repayment and no property stake; a resident donor can be a lender red flag.
Co-ownership Parents and daughter own as tenants in common in declared shares, for example father around 54% if £270k funds £500k price. Normal SDLT around £15k; no additional-dwelling surcharge if the parents replace their main residence. Shares remain in each estate for IHT and can qualify for PRR while occupied as main home. Strong Capital share, sale controls, occupation rights, and wills can align. Mortgage lender may require all owners to be borrowers; age/retirement and affordability criteria may fail.
Beneficial ownership behind sole title Daughter is registered proprietor but declaration of trust says parents own shares beneficially. Bare trust treatment generally looks through to the beneficiaries for SDLT; likely no FTB relief if parents have beneficial shares. Medium Better than a gift, but only if lender allows restrictions and interests are not postponed too far. Can be unacceptable to the lender because the lender wants priority and clear possession rights on default.
No-interest loan Father lends £270k to daughter, documented as repayable on agreed events or on demand. Daughter owns the home. Loan principal remains father's estate asset. HMRC says a repayable-on-demand interest-free loan is not itself a GWR, and POAT land contribution does not apply to a real loan. Medium Protects a debt claim, not a property share or permanent home. Lender affordability and source-of-deposit criteria. A hidden loan would be mortgage fraud risk.
Trust Trustees hold legal title for parents/daughter or with a life interest. Trust SDLT, relevant-property IHT charges, POAT/GWR, tax returns, and CGT reporting can arise. Potentially strong only with specialist drafting. Over-engineered and often mortgage-hostile for a normal family home purchase.

Gift With Reservation and POAT

Gift with reservation of benefit

GOV.UK's simple warning is that if someone gives something away but still benefits from it, the asset can still count in their estate. The classic example is giving a home to a relative but continuing to live there.

A pure cash gift is not the same as transferring the existing home, but it becomes risky if the father's cash is used to buy a home that he then occupies. The issue is not just seven-year survival; the adviser must test whether the arrangement is a genuine gift, a retained benefit, a shared-occupation case, or a POAT case.

Pre-owned assets tax

POAT is an income-tax charge aimed at people who once owned or funded assets and continue to enjoy them. HMRC's land contribution condition is broad: it can apply where a person directly or indirectly provided consideration for someone else to acquire land that the person later occupies.

There are important exceptions. HMRC says a real loan is not a land contribution because the debt remains repayable and in the lender's estate. HMRC also has exclusions and shared-occupation-style exemptions that can matter where a cash gift is traced into a jointly occupied home. This is a specialist tax-advice point, not a conveyancing afterthought.

Practical implication

An outright gift that is designed to save £5,000 of SDLT can create a much larger uncertainty: the father may lose capital protection, the lender may dislike a resident donor, and the tax adviser may need to analyse POAT/GWR annually or on death. If the father needs the money or needs a home for life, calling the £270k a gift is probably the wrong starting point.

Protecting Capital and Occupation

The documents need to match the economics and the mortgage. The following tools are common, but they are not interchangeable.

Declaration of trust

Sets beneficial shares, who pays mortgage/repairs/insurance, what happens on sale, buyout valuation, death, care move, daughter's relationship breakdown, and default. If father contributes £270k of a £500k price, a starting share is about 54%, but transaction costs and the daughter's cash/mortgage contributions should be allocated expressly.

Tenants in common and restriction

Tenants in common lets each owner leave their share by will. HM Land Registry practice uses a Form A restriction to protect trust interests and prevent a sole surviving proprietor from giving a receipt for capital money without another trustee or court order.

Occupation or life-interest rights

A contractual right to occupy, licence, lease, or life-interest trust can protect parents between family members. A mortgage lender will usually require any adult occupier to sign a consent or postponement deed acknowledging that lender possession rights come first.

Wills and survivorship

Wills must be updated at completion. Joint tenants pass by survivorship and can defeat intended shares. Tenants in common pass under wills or intestacy, so each parent's will should say who inherits the share and whether the survivor or daughter has an occupation right.

Mortgage Constraint

Regulated mortgage lenders must assess affordability before entering into the mortgage. That makes the legal structure inseparable from lender criteria.

  • Sole borrower, sole proprietor: best SDLT if the daughter gets FTB relief, but a resident parent providing £270k as a "gift" may be rejected unless the lender is comfortable with no repayment, no stake, and no right to remain. That may be unacceptable for the parents.
  • Joint owners, joint mortgage: legally clean but may fail if the retired parents' ages, income, term, or retirement status do not fit lender policy.
  • Joint borrower, sole proprietor: useful where a non-owner helps affordability. It is less useful here if the parents have no income to support the loan and need capital/occupation protection. Some products allow non-owner borrowers to live in the property, but criteria vary and independent legal advice is usually required.
  • Sole borrower with parental loan: can work only if the lender knowingly accepts the loan terms. If repayments are required, affordability is hit. If repayment is deferred until sale/death, some lenders still treat it as debt or require postponement.

CGT, IHT, and Care-Funding Issues

Compulsory-purchase sale

If the father's old home has been his only or main residence throughout ownership and the usual PRR conditions are satisfied, the compulsory-purchase sale should normally produce no CGT. PRR is about disposal of a main home; compulsory purchase does not by itself remove the relief.

Future CGT

Owners who occupy the new home as their only or main residence should usually get PRR on their own shares. If the daughter later moves out while retaining ownership, or if any share is held by someone who does not occupy as a main residence, future CGT can arise. The 2026/27 annual exempt amount is £3,000 for individuals and current main CGT rates are 18%/24% depending on income and gains.

Inheritance tax

The nil-rate band is £325,000 and the residence nil-rate band is up to £175,000 where a qualifying home or downsizing value passes to direct descendants. A couple may transfer unused allowances. A retained property share or an outstanding loan remains in the parent's estate; an outright gift may be a potentially exempt transfer unless GWR/POAT issues undermine the plan.

Care fees and deprivation of assets

England's 2026/27 care charging capital limits remain £14,250 and £23,250 in the current GOV.UK circular. The Care Act guidance says deprivation should not be automatically assumed, but councils can treat a person as still owning assets deliberately given away to reduce care charges. A move forced by compulsory purchase and a genuine need for suitable accommodation is a strong non-avoidance fact, but the documents should record that purpose.

No-Interest Loan Alternative

A no-interest loan is attractive because it can preserve the daughter's first-time-buyer SDLT relief while avoiding the worst gift-with-reservation and POAT problems. It must be real.

  • Document lender, borrower, principal, no interest, repayment date/events, default, whether early repayment is allowed, and what happens on sale, remortgage, death, care move, or family dispute.
  • Disclose it to the mortgage lender and conveyancer. Do not sign a gifted-deposit declaration if repayment is expected.
  • Expect affordability questions. Even if no monthly payments are due, the lender may treat the balance as a debt or require it to be postponed behind the mortgage.
  • If the father later forgives the debt, document the release by deed and treat that as a new IHT gift at that later date.
  • A secured second charge gives better protection but normally needs first-lender consent and may be rejected. An unsecured loan is easier for the mortgage but weaker for the father.

Recommendation

Recommended order of attack

  1. Start with the honest preferred structure: parents and daughter as tenants in common, with declared shares and occupation rights. Ask a broker whether any lender will accept the daughter/parents facts, including retired co-owners and a £202k mortgage.
  2. If lender criteria make co-ownership impossible, test a disclosed family-loan structure: daughter sole owner/borrower, father lends the £270k on deferred/no-interest terms, and all adult occupiers sign whatever lender consent/postponement is required. Accept that this protects capital less well than ownership.
  3. Avoid an outright gift unless the father can truly afford to lose the money and any right to stay. The tax/lender complexity is not justified by the £5,000 SDLT saving if the real intention is to preserve his home security.
  4. Avoid a trust unless a specialist private-client solicitor and tax adviser have a specific reason. For a normal family home purchase, it is likely to add cost, lender resistance, and tax administration without solving the mortgage problem.

Advice needed before exchange

Conveyancing solicitor: declaration of trust, title restriction, occupier consent, independent advice, wills interface, and lender reporting. Tax adviser: POAT/GWR, IHT, CGT shares, and care-fees documentation. Mortgage broker: lender acceptance for resident donors, family loans, JBSP, retired co-owners, term/age limits, and whether the daughter can borrow £202k on her own affordability.
