A buy to let mortgage differs from its residential counterpart in that it is largely assessed on the property’s profitability, i.e. how much rent it can generate vs. the cost of the mortgage – rather than on your own personal financial circumstances. Some buy to let lenders will require you to have a minimum salary, typically £20,000 or £25,000.
Once agreed, your buy to let mortgage enables you to rent out the property to tenants, whereas you cannot do this with a residential mortgage.
Our buy to let mortgage advice is always fee-free. In some circumstances — such as adverse credit cases or mortgages under £100,000 — a small arrangement fee may apply. Get in touch to discuss your specific situation.
There is no official limit on the number of buy to let mortgages you can hold. However, once you have four or more mortgaged buy to let properties, you are classified as a portfolio landlord. This means lenders must assess your entire portfolio, not just the new application, at each stage. Individual lenders may also set their own exposure limits, typically capping their own lending at three properties or limiting total background properties to between four and ten.
From fixed rate products to portfolio landlord rules, explore each topic in detail so you can invest with confidence.
Fixed rate BTL mortgages lock in your interest rate for a set period, keeping monthly costs predictable. Tracker mortgages follow the Bank of England base rate and often carry lower early repayment charges — ideal if you want more flexibility.
Own four or more mortgaged buy to let properties? You are a portfolio landlord. Lenders must assess your entire portfolio — total borrowing, rental income and void periods — at each new application. We help you navigate the criteria.
Want to keep your current home and move on? A let to buy mortgage converts your existing property into a buy to let, releasing equity to fund your new purchase. We arrange both mortgages together as part of the same process.
It is possible to purchase a buy to let property as your first ever property. Lender criteria differs from a standard residential application. We explain what is involved and which lenders will consider first-time landlords.
Standard home insurance does not cover missed rental payments, tenant damage or landlord liability. Specialist buy to let insurance — or portfolio cover for multiple properties — protects your investment properly.
Under the Rent Act 1977, some tenants have the right to remain in a property even if it is sold. Sitting-tenant properties are often priced lower, but many mainstream lenders will not finance them. We know which specialist lenders will.

A buy to let mortgage is secured against a property you intend to rent out rather than live in. Lenders primarily assess affordability based on the rental income the property can generate — typically requiring rent to cover 125–145% of the monthly mortgage payment. Deposits are higher than for residential mortgages, generally starting at 25%, and interest rates are usually a little higher too.
Most buy to let lenders require a minimum deposit of 25% of the property's purchase price. Some specialist products accept 20% or even 15% in certain circumstances. The larger the deposit, the better the rates available and the less rental income coverage the lender will demand. Your adviser will show you exactly which lenders and products are available at your deposit level.
Yes. There is no official limit on the number of buy to let mortgages you can hold. However, once you have four or more mortgaged buy to let properties, you are classified as a portfolio landlord and lenders must assess your entire portfolio at each application. Individual lenders may also cap how many they will provide to a single borrower or limit the number of buy to let mortgages you can hold with other lenders simultaneously.
A residential mortgage is for a property you live in; a buy to let mortgage is for a property you rent to tenants. The key difference is in how affordability is assessed — BTL lenders focus on rental income rather than personal salary. Deposits are typically higher (25%+), interest rates are slightly higher, and you cannot live in a BTL-mortgaged property without the lender’s permission.
