Can you get a buy-to-let mortgage with bad credit?
Yes — though your options will be narrower than for a borrower with a clean credit history. High-street lenders and building societies typically decline buy-to-let mortgage applications from people with CCJs, defaults, IVAs or other adverse credit markers. However, a growing number of specialist and challenger lenders take a fundamentally different approach.
Instead of relying on automated credit scoring, specialist BTL lenders manually underwrite each case. They look at the rental income, the property quality, the LTV, and the overall picture — not just the credit score number.
What types of adverse credit can be considered for BTL?
The following types of adverse credit are regularly considered by specialist BTL lenders, depending on the specifics:
CCJs (County Court Judgements)
Satisfied CCJs are viewed more favourably than unsatisfied ones. Lenders consider the age, value and number of CCJs. A single small CCJ registered three years ago will not prevent most specialist lenders from considering an application.
Defaults
Defaults on utility bills, telecoms and minor credit accounts are generally treated less severely than mortgage or secured loan defaults. Multiple recent financial defaults are more challenging.
IVAs (Individual Voluntary Arrangements)
Some specialist lenders will consider BTL applications from borrowers who are one to two years post-discharge of an IVA. Active IVAs are more difficult, but not impossible for larger loans with strong security.
Bankruptcy
Discharged bankruptcy is considered by select lenders — typically requiring at least 12 to 24 months to have passed since discharge, with a strong application otherwise.
Missed mortgage or secured loan payments
These are treated more seriously than unsecured credit defaults. However, lenders will consider the context — particularly if the missed payments are explained (e.g. a period of illness or job loss) and the situation has since been resolved.
How is affordability assessed on a BTL mortgage?
Unlike a residential mortgage, buy-to-let affordability is primarily assessed on rental income — not your personal income. The standard requirement is that the monthly rent covers 125%–145% of the monthly mortgage payment at a stressed interest rate (often 5%–6%).
This means that a property with strong rental demand in a good yield area may satisfy affordability criteria even where personal income is modest. Some specialist lenders also offer "top slicing" — supplementing rental income with personal income for affordability purposes — which can help with lower-yield properties.
What LTV is available for adverse credit BTL?
Most specialist BTL lenders for adverse credit borrowers work up to 75% LTV. In some cases, 80% LTV may be available for borrowers with minor adverse credit and a very strong application, but this is less common.
If you can offer a lower LTV — for example by using equity from an existing property, or by providing a larger cash deposit — your options will expand considerably. At 65% LTV or below, many lenders become significantly more flexible on adverse credit.
Do portfolio landlords with adverse credit have options?
Yes. If you own four or more mortgaged buy-to-let properties, you are classified as a portfolio landlord. Under PRA regulations, lenders must assess the entire portfolio when you apply for additional BTL finance — not just the individual property.
Specialist BTL lenders experienced in portfolio cases understand this regulatory framework. They assess the overall portfolio coverage ratio and balance sheet, rather than applying rigid per-property rules. A strong portfolio with good overall coverage can outweigh adverse credit history in many cases.
How to improve your chances of approval
There are several practical steps that can improve your BTL mortgage application despite adverse credit: pay off any unsatisfied CCJs before applying; ensure you are on the electoral roll; correct any errors on your credit file; provide a larger deposit to reduce LTV; and choose a property with strong rental demand rather than a niche property type.
Working with a specialist credit introducer who has access to lenders not available on the high street is also critical — which is where we come in.
