A buy-to-let arrears mortgage is a specialist borrowing scenario, not a straightforward tick-box application. Whether you are trying to remortgage a rental property, replace an expiring deal or raise funds to stabilise your position, arrears will need careful explanation and the right lender criteria.
The key question is not simply whether arrears appear on your credit file. Lenders will want to understand what happened, whether the issue is resolved, and whether the property can support the new mortgage going forward. A missed payment during a short-term disruption is viewed very differently from ongoing arrears that are still increasing.
What counts as arrears on a buy-to-let application?
The word arrears can cover several different situations, and they do not all carry the same weight. Mortgage arrears on the buy-to-let property are usually the most significant, particularly if they are recent or remain unpaid. Arrears on a residential mortgage, secured loan, credit card, loan or utility account may also be relevant if they appear on the credit file.
Rental arrears are slightly different. A tenant falling behind with rent does not automatically create a credit-file issue for the landlord, but it can affect the affordability of the mortgage. If the rent has not been received consistently, a lender may question whether the property provides enough income to meet its mortgage payments.
For a limited company buy-to-let, lenders will commonly assess the credit history of the directors and shareholders as well as the company structure. It is therefore rarely enough to say that the property is held in an SPV company if personal credit issues have contributed to the situation.
How lenders assess a buy-to-let arrears mortgage
Specialist lenders generally look beyond the fact that an arrears marker exists. Their underwriting will focus on the details behind it. This is why submitting an application to the wrong lender, or without a clear explanation, can lead to an avoidable decline.
How recent the arrears are
Arrears from several years ago that were settled and have not been repeated are often easier to place than missed payments in the last six or twelve months. Recent arrears do not necessarily make borrowing impossible, but they narrow the available lender options and may require a lower loan-to-value.
Current mortgage arrears are more difficult. A lender will need to see how they are being managed and why a remortgage is a credible solution rather than a way of delaying a problem. If possession action, a suspended possession order or a formal repayment arrangement is involved, the case needs particularly careful handling.
The reason payments were missed
A temporary gap in rental income, illness, a relationship breakdown, delayed insurance proceeds or an unexpected property repair can all affect a landlord’s ability to pay. The explanation should be honest, supported where possible, and matched by the evidence in your bank statements and credit report.
Lenders are less concerned with polished explanations than with a clear picture of what has changed. For example, if the tenant has been replaced, the property has been refurbished and a new tenancy is in place, that may show the income issue has been addressed. If personal borrowing caused the arrears, lenders may consider whether those commitments have now been cleared or reduced.
Whether the arrears have been repaid
Settled arrears are generally easier to work with than outstanding balances. That said, paying off an arrears balance immediately before applying does not remove the payment history. The lender may still ask for statements, evidence of the arrangement and confirmation that the account is now up to date.
Where arrears remain, a remortgage may be possible in limited circumstances, but the figures must work. There must be enough equity to repay the existing mortgage and any fees, while meeting the new lender’s maximum loan-to-value and rental affordability rules.
The property income and loan-to-value
Buy-to-let lending is usually driven by the expected rental income as well as the amount you want to borrow. The lender will calculate whether the rent meets its required interest coverage ratio, often using a stressed interest rate rather than the initial pay rate.
A lower loan-to-value can make a material difference where there has been adverse credit. More equity gives the lender a greater margin of security and can widen the pool of available products. However, it is not a substitute for a viable rental income calculation. A property with weak rent for its value may still be difficult to remortgage, even with a substantial deposit or equity stake.
Your options if you have buy-to-let mortgage arrears
The right route depends on whether the arrears are current, settled or related to a different account. For landlords nearing the end of a fixed rate, a product transfer with the existing lender may be worth considering first. It can sometimes involve fewer underwriting checks than a full remortgage, although this is not guaranteed and the lender may still need the account to be fully up to date.
A full remortgage can offer a way to move to a lender whose criteria better suit your circumstances. This may be relevant if your existing lender will not offer a new product, the current payment is unaffordable, or you need to consolidate secured borrowing as part of the transaction. Consolidating debt into a mortgage can reduce monthly payments but may increase the total amount repaid over time, so it needs to be considered carefully.
For some landlords, the sensible immediate step is not a new mortgage application at all. If arrears are active and the property is under pressure, speaking to the existing lender early may create time to agree a repayment arrangement or discuss a temporary solution. Ignoring letters or missing further payments usually reduces the options available later.
Selling the property can also be the right answer where the rental income no longer supports the borrowing and there is sufficient equity. It is not a failure to conclude that a remortgage would only postpone a longer-term problem. Good mortgage advice should identify when a proposed loan is sustainable, not merely possible.
Preparing the application properly
A well-prepared application gives the lender a clearer reason to consider the case. Before applying, obtain copies of your credit reports and check that account balances, default dates and payment markers are accurate. Raise disputes over genuine errors before an application is submitted, as correcting a report after a lender has declined can be too late for that particular case.
You should also be ready to provide recent mortgage statements, tenancy agreements, evidence of rental payments, bank statements and proof of income where required. If there was a specific event behind the arrears, supporting documents may be useful, but they should be relevant rather than excessive.
For portfolio landlords, lenders may review your wider position rather than assessing the remortgaged property in isolation. They can look at total borrowing, rental income across the portfolio, property values, personal income and any unsecured commitments. A late payment on one property can therefore have a wider effect if it suggests that the overall portfolio is overstretched.
It also helps to be realistic about timing. A specialist buy-to-let remortgage involving recent arrears may take longer than a simple product switch because the lender will need to review explanations, statements and the valuation. Starting the process well before an existing fixed rate ends gives more room to consider the available routes without pressure.
Avoiding common mistakes
The most common mistake is making multiple applications in quick succession after an initial decline. Each lender has its own approach to arrears, loan-to-value, rental calculations and portfolio exposure. A decline from one lender does not establish that every lender will say no, but repeated hard searches can make an already complex case harder to present.
Another issue is underestimating the importance of the valuation. A landlord may believe there is enough equity based on a previous value, only to find that the new valuation is lower or that the achievable rent does not meet the lender’s calculation. It is better to model the case conservatively from the outset.
Selective Mortgages works with landlords whose circumstances need more than an automated decision. The aim is to establish the facts first, identify lenders whose criteria may fit, and present the application with the right supporting information.
Arrears can feel like a barrier to any further borrowing, especially after a difficult period with a tenant or an existing lender. But the most useful next step is a clear assessment of the arrears, the property income, the available equity and what has changed since the problem occurred. That gives you a sounder basis for deciding whether a remortgage is realistic and, just as importantly, whether it is the right move for your property.
