Common questions from landlords and property investors about buy-to-let mortgages, our sourcing tool and BTL calculator.
A buy-to-let (BTL) mortgage is a loan specifically designed for landlords purchasing property to rent out rather than live in. Unlike a residential mortgage, eligibility is assessed primarily on projected rental income — lenders typically require rental income to cover 125%–145% of the monthly interest at a stressed rate. Most BTL mortgages are interest-only, meaning you pay only the interest each month and repay the full capital at the end of the term.
Most buy-to-let mortgage lenders require a minimum deposit of 25% (75% LTV), though some specialist products are available at higher LTVs. If you're a portfolio landlord or using a limited company (SPV), some lenders may require 30–40% deposit. Larger deposits generally unlock lower buy-to-let mortgage rates.
Yes. Limited company (SPV) buy-to-let mortgages have grown significantly as landlords seek tax efficiencies. Dynesourcer includes criteria filtering for limited company BTL applications, including SPV structure, director guarantees and Companies House status. Our broker team can guide you through the application process.
Our free BTL mortgage calculator lets you input the property value, loan amount, expected rental income and mortgage term to instantly see monthly repayments, interest cover ratio (ICR), arrangement fee impact, and true cost over the initial product period. This helps you compare deals by actual cost rather than just headline rate.
Yes. Dynesourcer is built for specialist BTL scenarios including HMOs (Houses in Multiple Occupation), multi-unit freehold blocks (MUFBs), and portfolio landlords with four or more mortgaged properties. Our sourcing criteria filter matches you only to lenders whose criteria your case fits.
Sourcing and submitting an online enquiry through Dynesourcer is completely free — there's no cost to compare buy-to-let mortgage products, use the BTL calculator, or shortlist deals. A broker fee applies when you proceed to a full mortgage application, which covers expert case preparation, lender submission and end-to-end support through to offer. You'll be made aware of any fee before you commit.
