Frequently Asked Questions
What deposit do I need for a BTL mortgage?
Most lenders require 25-30% deposit for BTL. Some specialist lenders accept 15-20% for experienced landlords, but rates will be higher.
Interest only vs repayment - which is better for BTL?
Interest only gives higher cashflow but no equity building. Repayment builds equity but has lower cashflow. Many BTL investors use interest only and invest the difference.
How do lenders stress test BTL mortgages?
Lenders typically stress test at 5-6% or 2% above the product rate (whichever is higher), and require rental income to cover 125-145% of mortgage payments.
What is ICR on BTL mortgages?
Interest Coverage Ratio (ICR) is the rental income divided by mortgage interest. Lenders typically require 125-145% ICR meaning rent must be 1.25-1.45x the interest-only payment.
Can I get a BTL mortgage with no experience?
Yes, but it's harder. Most lenders require at least 1 years BTL experience or being a first-time landlord with significant deposit (30%+). Some newer lenders offer first-time landlord products.
