Mortgages and Finance for Property Investors

Property investment covers many different routes — from a single buy-to-let flat to a commercial unit, a renovation project or a development site. This page helps you work out which type of finance usually fits your plan, and where to read more.

Written by Matt Stevens, Mortgage & Protection Adviser, The Mortgage Genie

The short answer

There isn't a single "investor mortgage" — the right route depends on what you're buying, how you'll hold it, and what you plan to do with it. A standard residential buy-to-let mortgage suits a single let property with a tenant on an assured shorthold tenancy. A commercial mortgage suits a business premises or mixed-use building. Bridging finance suits a fast purchase, an auction deadline, or a property that needs work before it can be mortgaged in the usual way.

Below is a short guide to help you work out the likely route, followed by more detail on each one. We can talk through your plan and explain the options in more detail.

Our service: We handle residential and buy-to-let mortgages, including Ltd Co buy-to-let, directly within our permitted service. For commercial and other specialist finance, our team will discuss your requirements and, where appropriate, identify a suitable partner adviser. We will explain who they are and obtain your permission before sharing your details.

Which finance fits your plan?

This table is a starting point, not a recommendation. Many purchases could use more than one route, and the right answer depends on your circumstances, the property, and what lenders are willing to consider at the time.

Some scenarios — HMOs, holiday lets and larger portfolios, for example — fall outside a standard buy-to-let mortgage and need lenders who specialise in that type of letting. We cover the general position for these below; speak to us about your specific plan.

Letting residential property

Residential buy-to-let

A standard buy-to-let mortgage is for a single self-contained property let to tenants on an assured shorthold tenancy. Lenders usually assess the rental income the property can achieve against the mortgage payment, using an interest cover ratio, alongside your deposit and overall circumstances. See our

Our buy-to-let mortgages page covers the basics, and our rental yield guide and buy-to-let calculator can help with early numbers.

Limited company

Many investors now buy through a limited company (often a special purpose vehicle). This changes how tax and lending criteria apply, and lenders assess the company and its directors differently to an individual. See our

guide for limited company directors. Different tax treatment may apply to company ownership versus personal ownership — take independent tax advice before deciding.

Portfolio landlords

If you already hold, or plan to build, four or more mortgaged buy-to-let properties, you're usually treated as a 'portfolio landlord'. Lenders then look at your whole portfolio — overall borrowing, experience and cash flow — not just the property being financed, which can affect which lenders will consider your application.

If you're refinancing existing lets, see our guide to buy-to-let remortgages and an anonymised portfolio refinancing case study.

HMOs and multi-unit

Houses in multiple occupation (HMOs) and multi-unit freehold blocks are let room-by-room or as several self-contained units. They usually need a specialist mortgage rather than a standard buy-to-let product, and local licensing rules may apply. We can talk through what's involved and the lenders who may consider this type of letting.

Holiday lets

Short-term and holiday letting is assessed differently from standard tenancies, usually against seasonal income projections rather than a single AST rent. This needs a specialist holiday-let mortgage; we can explain how lenders approach it.

Commercial and mixed-use investment

If you're buying a business premises, an investment unit let to a commercial tenant, or a mixed residential-and-commercial building, this usually falls under commercial or semi-commercial lending rather than a residential buy-to-let mortgage. Commercial lenders look at lease terms, tenant covenant strength, and debt service cover rather than a standard rental stress test. Visit our commercial mortgages hub for the full picture, including business premises, commercial buy-to-let, farms and agricultural land.

Buying at auction

Auction purchases come with a contractual deadline that is usually much shorter than a standard mortgage can complete within, which is why many auction buyers use bridging finance to complete, then refinance afterwards onto a standard mortgage. The deadline is set by the contract and auction house, not by any finance provider.

Read our auction finance guide for how the process works, or go straight to auction bridging finance if you already have a property in mind.

Refurbishing or developing

Refurbishment

Light to moderate refurbishment — redecoration, a new kitchen or bathroom, cosmetic repairs — can often be funded through a refurbishment bridging loan, with the property refinanced onto a standard mortgage once the work is complete and the property is let or lived in.

Development finance

Ground-up building, major structural work, or large-scale conversions usually need a development finance facility rather than an ordinary bridging loan — typically drawn down in stages against the cost of works, with a monitoring surveyor overseeing progress. There is no dedicated development finance page on this site, but we can discuss development finance as a separate facility if this applies to your project.

Land

Buying land — with or without planning permission — carries its own risks around planning and valuation, and is usually financed separately from the building works that follow. See land bridging for more detail, and our wider bridging finance hub for how bridging works more generally, including bridging for refurbishment and development.

Remortgaging and raising capital

Many investors fund their next purchase, or a refurbishment, by remortgaging an existing property or taking a further advance to release some of the equity in it. See remortgaging and releasing equity for how this works, and second-charge mortgages if you want to keep your existing mortgage in place and add a second loan behind it.

Interest-only lending

Interest-only lending is common for investment property, since it keeps monthly payments lower and the capital is repaid later — usually from sale, refinancing or other funds. Lenders will want a credible repayment strategy for the capital. See interest-only buy-to-let mortgages and, for commercial lending, interest-only commercial finance.

Property types and lender criteria

Some property types attract extra scrutiny from lenders — non-standard construction, flats above commercial units, properties needing significant work, or purchases below market value. These don't rule out finance, but they narrow which lenders will consider the case. See our property types hub, including flats above shops, fixer-uppers and below market value purchases. If you're planning to build your own home, see our self-build mortgage guide.

Frequently asked questions

Not necessarily the same product, but the right type of finance depends on the property and how you plan to use it. A single let flat, a limited company portfolio, a commercial unit and an auction purchase can all need different routes, which is why we assess each case individually.

Some buy-to-let lending is regulated and some is not. It depends on the borrower, the security, its use and any applicable exclusions. The adviser handling your case will explain the position for your proposed borrowing.

Bridging finance is short-term and usually more expensive than a standard mortgage, so it tends to suit situations with a deadline or a property that isn't mortgageable yet — such as an auction purchase or a refurbishment project — rather than long-term holding. Most borrowers plan to repay it through a sale or a remortgage.

If you hold, or plan to hold, four or more mortgaged buy-to-let properties, lenders usually assess you as a portfolio landlord and look at your whole portfolio's finances rather than just the property you're financing.

This depends on your tax position, how you plan to grow your portfolio, and your personal circumstances. Different tax treatment may apply to each structure — take independent tax advice before deciding, and we can explain the lending implications of each route.

Tell us what you're trying to buy and how you plan to use it, and we'll explain which type of finance is usually used for that scenario, what lenders are likely to want to see, and the risks involved.
