How Adverse Credit Affects Your Buy to Let Options: Clear Guidance & Real Solutions
Many landlords assume adverse credit automatically prevents them securing a buy-to-let mortgage. In reality, the buy-to-let market is often more flexible than residential lending, with several lenders specialising in applications from borrowers with imperfect credit histories. Your options depend on the type of adverse credit, how recent it is, and how strong the rental coverage looks.
This guide explains how adverse credit affects your buy to let options, which lenders may still consider your application, and what steps can help strengthen your profile. This article provides general information only and does not offer regulated mortgage advice.
What Counts as Adverse Credit?
Lenders typically class the following as adverse credit:
- Missed or late payments
- High credit utilisation
- Defaults
- CCJs
- IVA or bankruptcy (historic or settled)
- Debt management plans
- Payday loans
- Repossessions
- Returned direct debits
- Credit file disputes
Not all adverse issues carry the same weight, and buy-to-let lenders assess them differently depending on risk level and timing.
Why Buy to Let Lenders Assess Adverse Credit Differently
Buy-to-let mortgages are viewed primarily as investment borrowing. Because repayments are usually supported by rental income, some lenders:
- Place more weight on rental yield than personal income
- Accept applicants with past adverse credit if the property is financially strong
- Use more flexible underwriting approaches
However, others mirror residential criteria closely and may decline for recent or significant adverse credit. Lender choice varies widely, which is why understanding your profile is essential.
How Different Types of Adverse Credit Affect Your Buy to Let Options
1. Missed or Late Payments
Impact depends on:
- How recent they are
- Whether multiple accounts were affected
- Whether payments are now stable
Older or isolated late payments may have minimal effect.
2. High Credit Utilisation
Lenders view this as a sign of financial pressure.
Buy-to-let lenders may still consider your case if:
- Utilisation is decreasing
- Bank statements are stable
- Rental coverage is strong
3. Defaults
Defaults affect lender choice, particularly if:
- They occurred within the last 2–3 years
- Multiple defaults were recorded
- They remain unsettled
Specialist lenders often accept older or settled defaults, especially if deposit size is strong.
4. CCJs (County Court Judgments)
Key factors include:
- Value of the CCJ
- Age
- Whether it is settled
- Whether multiple CCJs exist
Many buy-to-let lenders accept settled CCJs older than two years, while some specialist lenders accept more recent cases.
5. Debt Management Plans (DMPs)
Some lenders may accept applicants:
- Who are actively repaying a DMP
- Who completed a DMP more than 12–24 months ago
Affordability must clearly support both personal and investment borrowing.

6. Payday Loans
Recent payday loans are viewed as high-risk.
Older, isolated payday loans may be ignored if the rental income is strong and overall conduct has improved.
7. IVA or Bankruptcy
Specialist buy-to-let lenders may consider applicants:
- Three or more years post-discharge for bankruptcy
- Once an IVA is completed and sufficiently aged
Deposit requirements may increase significantly (30–40%).
8. Repossessions
Lender choice becomes highly specialised.
Strong rental performance and a substantial deposit are usually required.
How Recency of Adverse Credit Influences Outcomes
Within the last 6–12 months
Most restrictive.
Lenders may require:
- Higher deposits
- Manual underwriting
- Strong rental coverage
1–3 years old
More specialist lenders open up, particularly if the issue was isolated.
3–6 years old
Many lenders can consider, depending on deposit size and rental strength.
6+ years old
Adverse items typically drop off your credit file and have little or no impact.
How Deposit Size Changes Your Buy to Let Options
Deposit size is one of the strongest tools available when applying with adverse credit.
| Deposit Size | Lender Flexibility |
|---|---|
| 20% | Limited, especially with recent adverse issues |
| 25% | Standard BTL level; some adverse still accepted |
| 30–35% | Many specialist lenders open up |
| 40%+ | Strongest position for applicants with severe or recent adverse credit |
Larger deposits reduce lender risk and help applications pass rental stress tests.
Rental Income and Stress Testing
Even with adverse credit, lenders focus heavily on rental income.
Typical ICR (Interest Coverage Ratio) requirements:
- 125%–145% for limited companies
- 140%–170% for individuals
- Higher rates for higher-rate taxpayers
If rental income comfortably meets or exceeds the stress requirement, lenders may be more flexible about credit issues.
Buy to Let Affordability for Applicants With Adverse Credit
Unlike residential mortgages, BTL affordability is mainly based on rental income rather than salary. However, lenders still check:
- Your personal outgoings
- Existing residential mortgage conduct
- Your ability to cover payments during void periods
- Overall financial stability
Clean bank conduct (no unarranged overdrafts, no returned payments) is particularly important.
Property Type and Impact on Adverse Credit Applications
Some property types are considered higher risk and may require stronger credit profiles or higher deposits, including:
- HMOs (Houses in Multiple Occupation)
- Multi-unit freehold blocks
- Flats above commercial premises
- New-build flats
- Holiday lets
Applicants with adverse credit often have more success when choosing standard single-unit BTL properties.
Common Scenarios and Likely Outcomes
Scenario 1: One default from four years ago, now settled
Many BTL lenders still consider this acceptable at 25% deposit.
Scenario 2: Multiple late payments last year
Specialist lenders may accept if rental income is strong and bank conduct has improved.
Scenario 3: A CCJ from 18 months ago, recently settled
Possible with a larger deposit (30–35%).
Scenario 4: Bankruptcy discharged three years ago
Specialist lenders with higher deposit requirements may consider.
Scenario 5: High credit utilisation but no missed payments
Improved recent conduct and stable statements can support approval.
How to Improve Your Buy to Let Chances With Adverse Credit
(General Information Only)
1. Maintain clean payment behaviour for 6–12 months
Lenders strongly prioritise recent conduct.
2. Reduce credit utilisation
Lower utilisation signals improved financial stability.
3. Avoid new credit applications
Multiple searches may affect lender appetite.
4. Strengthen your deposit
A higher deposit significantly expands your lender options.
5. Gather supporting documents
These may include:
- Explanations for adverse credit
- Updated bank statements
- Proof of rental estimates or letting agent letters
6. Consider buying through a limited company
Some lenders apply more favourable stress calculations for SPVs (seek independent tax advice).
Summary
Understanding how adverse credit affects your buy to let options helps investors make informed decisions. The key points are:
- Many BTL lenders accept a range of historic adverse credit
- Recency and severity determine lender choice
- Deposit size strongly influences the outcome
- Rental income and stress tests play a key role
- Specialist lenders provide real solutions when mainstream lenders cannot
With the right preparation and clear expectations, applicants with adverse credit can still secure buy-to-let mortgages and grow property investment portfolios.
