## Mortgage Overview
A *BTL mortgage adverse credit London* is a specialist buy-to-let mortgage designed for property investors who have a less-than-perfect credit history. These products allow landlords to purchase or remortgage investment properties, even with past financial difficulties such as County Court Judgements (CCJs), defaults, or missed payments.
There are several types of BTL mortgage products available:
– **Fixed-rate mortgages** (typically 2–5 years): Offer payment stability
– **Variable-rate mortgages:** Linked to lender’s standard variable rate
– **Tracker mortgages:** Track the Bank of England base rate plus a margin
These mortgages are suitable for:
– First-time landlords with historic credit issues
– Portfolio landlords managing multiple properties
– Investors using a **limited company** structure
– Those looking to **remortgage** to release equity or secure better rates
Unlike residential mortgages, BTL mortgages are assessed primarily on **rental income**, not personal income. However, affordability is still stress-tested, and lenders will consider your overall financial profile. (Learn about limited company buy-to-let)
