Remortgaging or Buying a Buy‑to‑Let: When to Instruct a Solicitor, Typical Timelines and Documents You’ll Need

If you are planning to remortgage your home or buy a buy‑to‑let property, you will quickly come across questions about when to instruct a solicitor, how long the process takes and what paperwork you need to have ready.

This guide gives an overview of the remortgage conveyancing process and buy‑to‑let purchases, so you can plan ahead and understand what to expect. It is general information only and not legal advice; you should obtain advice tailored to your own situation before making decisions.

Do You Need a Conveyancing Solicitor to Remortgage?

When you switch to a new lender, you will usually need a conveyancing solicitor or licensed conveyancer to handle the legal work, including checking the title, dealing with your existing mortgage and registering the new charge at HM Land Registry.

If you stay with your current lender and simply move onto a new product (often called a “product transfer”), there is usually less legal work and a solicitor may not be required in the same way, although requirements vary between lenders.

For buy‑to‑let mortgages, particularly where a company is involved, there are often additional checks and lender conditions, so independent legal advice and a conveyancing solicitor are usually needed.

When Should You Instruct a Solicitor for a Remortgage?

Many homeowners start thinking about remortgaging around three to six months before their current fixed‑rate deal ends, so there is time to explore options and complete the process.

If you are changing lender, it can be helpful to choose your conveyancing solicitor once you have a mortgage offer in progress or shortly beforehand, so they are ready to begin the legal work as soon as your lender issues the offer.

Buy‑to‑let remortgages or purchases can involve extra steps, such as reviewing tenancy arrangements or company documents, so landlords may prefer to involve a solicitor earlier to check what the lender will require.

How Long Does a Remortgage Take? Typical Timelines

The exact remortgage timeline depends on your lender, your circumstances and how quickly documents are provided, but many guides suggest that a straightforward remortgage can take around four to eight weeks from application to completion.

A simplified timeline might look like this:

Stage 1 – Application and agreement in principle (around 1–2 weeks):

You or your broker choose a deal and submit an application, providing details about your income, outgoings and the property.

Stage 2 – Valuation and lender checks (around 2–4 weeks):

The lender carries out a valuation and affordability assessment and, if they are satisfied, issues a formal mortgage offer.

Stage 3 – Legal work and completion (around 4–8 weeks):

Your conveyancer checks the title, deals with any lender conditions, obtains a redemption statement from your existing lender and arranges completion and registration of the new mortgage.

Timeframes can be shorter or longer depending on factors such as leasehold properties, complex ownership structures or delays in obtaining information, so it is sensible to allow some flexibility.

What Is Different About Buy‑to‑Let Conveyancing?

Buy‑to‑let conveyancing involves many of the same steps as residential conveyancing, but there are additional considerations for landlords and lenders.

Your solicitor will usually check that the property can lawfully be rented out, review any existing tenancy agreement and confirm matters such as remaining lease length and any restrictions in the title that might affect letting.

Lenders often have specific criteria for buy‑to‑let mortgages, including minimum rental coverage and requirements relating to company structures if the property is owned through a limited company, which your solicitor will need to take into account when dealing with mortgage instructions.

What Documents Do You Need for a Remortgage?

Requirements differ between lenders, but remortgage guides often highlight the following examples of documents that are commonly requested.

Personal and Financial Documents

You will usually be asked for items such as:

Proof of identity, for example a valid passport or driving licence.

Proof of address, such as recent utility bills or bank statements.

Proof of income, for example recent payslips and a P60 if you are employed, or tax calculations and accounts if you are self‑employed or a company director.

Recent bank statements showing income, regular payments and financial commitments.

Property and Mortgage Information

Your conveyancing solicitor will typically need:

Details of your current mortgage and lender, so they can obtain a redemption statement showing how much is owed and any early repayment charges.

Title information from HM Land Registry to confirm ownership and any existing charges or restrictions on the property.

For leasehold properties, information about the lease, ground rent and service charges, and any notices that must be given to the landlord or managing agent.

For buy‑to‑let properties, you may also be asked for:

A copy of any current tenancy agreement and details of the rent.

Company documents, if the property is owned by a company, such as incorporation details and information about directors and shareholders, depending on the lender’s requirements.

Having these documents ready early can help the remortgage conveyancing process run more smoothly.

Practical Tips for Planning a Remortgage or Buy‑to‑Let Purchase

Make a note of when your current mortgage deal ends and start looking at your options well in advance.

Gather key documents such as ID, income evidence and recent bank statements before you start, so you can provide them promptly when asked.

Consider speaking to both a mortgage adviser and a conveyancing solicitor so you understand the financial and legal aspects of your plans.
