Buying a home together can be incredibly exciting, especially when one partner is stepping onto the property ladder for the first time and the other has previous homeownership experience. 

Each partner brings unique circumstances, advantages, and potential hurdles to the mortgage process. With thoughtful preparation and the right advice, buying together can be smooth and successful.

Understanding your joint mortgage options

When one partner is already a homeowner and the other is a first-time buyer, lenders may apply different rules and affordability criteria. Whilst getting a mortgage broker’s advice isn’t strictly essential, they can provide clarity, carefully explaining the impact of your mixed status on your mortgage options.

They can match you with lenders whose criteria align best with your specific circumstances, potentially securing more favourable terms or better interest rates than you might find by yourself.

Navigating stamp duty complexity

Stamp duty becomes trickier when buying jointly, especially if one partner already owns a property. Typically, first-time buyer stamp duty relief doesn't apply if one applicant already owns or has owned property previously.

This means you will unfortunately have to pay stamp duty even when just one of you is an existing homeowner.  

Using existing equity wisely

Leveraging equity from one partner's existing property can significantly boost your deposit, reduce mortgage costs, and open up more favourable mortgage deals. You can access this equity efficiently through options like remortgaging or property sales, ensuring optimal timing and maximizing the benefits based on your individual financial goals.

Managing unequal deposits

Often, one partner can contribute more substantially to the deposit of your new home, particularly if they already own property. To protect each partner’s financial interests, legal agreements like a deed or declaration of trust are recommended. 

Such arrangements provide transparency, clearly outlining each person's investment and rights, and greatly reducing potential future disputes.

The panel solicitors recommend by Avant will be able to help you with this. 

Choosing the right ownership structure

Choosing between owning property as joint tenants or tenants in common can significantly impact your future financial planning. Joint tenants own equal shares, automatically inheriting the property upon the other's death. 

Tenants in common allows unequal ownership percentages and the flexibility to leave your share to chosen beneficiaries.

Again, your solicitor will be happy to advise you on this!

Strengthening your mortgage application

Mortgage affordability assessments are particularly detailed when one applicant already has mortgage commitments. 

A broker can give guidance to help improve your chances of approval by optimising your combined financial profiles, advising you on how to present your finances clearly, and choosing lenders more likely to approve your specific situation.

Early repayment charges and porting your mortgage

If the homeowner still has a mortgage with early repayment charges (ERCs) due to being within the initial deal period, there could be an option to port (transfer) that existing mortgage to the new property while adding the first-time buyer onto the mortgage. This approach can avoid costly penalties and retain potentially advantageous mortgage terms.

Communication and financial transparency

Transparency about financial matters is key when taking out a joint mortgage. Both partners should openly discuss debts, income disparities, financial expectations, and future financial plans. Creating a shared financial vision and being upfront from the outset can strengthen your relationship and ensure smoother homeownership.
