Buy-to-let market sentiment in May 2026: Why landlords are restructuring portfolios and locking in fixed rates

Buy-to-let landlords are not necessarily leaving the market in May 2026, but many are becoming far more selective. Higher borrowing costs, new rental rules, tighter tax pressure and slower rent growth mean you now need to review every property on its own numbers, not just assume the whole portfolio still works.

For many landlords, the main question is no longer “should I buy another property?” It is “which properties deserve more capital, which should be refinanced, and which may need to be sold before they drain cash flow?”

That is why portfolio restructuring and fixed-rate mortgage decisions have moved to the top of the landlord agenda. If you own one rental property or a larger portfolio, this is a sensible time to look at debt, tax, repairs, yield, compliance costs and future reporting obligations together.

FHP Accounting works with landlords, property investors and property managers who need practical, clear support from accountancy firms in Nottingham with property sector experience. The right advice can help you move from reactive decisions to a proper financial plan.

What buy-to-let sentiment looks like in May 2026

The mood in the buy-to-let market is cautious, but not completely negative.

There is still demand for rental homes, and rental income remains strong in many areas. Official figures show average UK private rents increased by 3.5% in the 12 months to April 2026, reaching £1,381 per month. However, rent growth has cooled compared with the sharp increases seen in recent years, and tenants are under pressure from wider living costs.

At the same time, landlords are facing a more expensive and more regulated market. Mortgage rates have been volatile, and the Bank of England base rate sits at 3.75%. Buy-to-let fixed rates moved upwards during March and April 2026, which has made refinancing decisions harder for landlords who were hoping for cheaper borrowing this year.

You may still have a profitable property on paper, but the gap between rent received and costs paid can be much narrower than it was a few years ago.

That is why many landlords are reviewing:

1. Mortgage terms and expiry dates
2. Interest cover ratios
3. Rental yield by property
4. Repair and compliance costs
5. Tax position after mortgage interest restrictions
6. Whether personal or limited company ownership still fits
7. Whether weaker properties should be sold
8. Whether stronger properties should be refinanced or improved

If you want a deeper look at the tax side, FHP’s guide to Renters’ Rights Act 2026 financial planning is a useful related read.

Why landlords are locking in fixed rates

Many landlords are locking in fixed rates because they want certainty.

That does not always mean a fixed rate is the cheapest option. It means the landlord can plan. When your rental income, mortgage payments, insurance, maintenance, tax and service charges are all moving, a fixed mortgage payment can make cash flow easier to manage.

For example, if you have a £250,000 buy-to-let mortgage and your monthly interest cost jumps by several hundred pounds, the impact is immediate. You may still be receiving the same rent, but your monthly surplus could shrink or disappear.

A fixed rate helps you answer simple but important questions:

1. Can the property still cover its mortgage and running costs?
2. How much should you keep aside for repairs?
3. Can you afford void periods?
4. Would a rent increase be realistic and lawful?
5. Would selling the property release capital for a better opportunity?

You should also look at your lender reporting. If you use cloud accounting, Xero reporting packs for lenders and investors can help you present income, costs and cash flow more clearly when refinancing.

Why restructuring is becoming more common

Restructuring does not always mean selling everything or moving every property into a limited company. It usually means taking a more disciplined look at what each property is doing.

A simple portfolio review might show that one property produces a strong yield, low repairs and steady tenants, while another has high debt, high maintenance costs and weak cash flow. In that case, holding both properties without review may not make sense.

Some landlords are restructuring by selling weaker assets. Others are refinancing, reducing debt, investing in energy efficiency, changing ownership structures, or focusing on areas with stronger rental demand.

If your portfolio is becoming more complicated, support from an accountant for landlords can help you understand what is happening underneath the headline rent figure.

The tax pressure behind landlord decisions

Tax is one of the biggest reasons landlords are reviewing their portfolios.

If you own residential property personally, mortgage interest relief is restricted. Instead of deducting all finance costs from rental income before calculating tax, you usually receive basic-rate tax relief on qualifying finance costs. This can be painful if you are a higher-rate or additional-rate taxpayer.

That means a property can look profitable in your bank account but still create an awkward tax position.

You also need to think about:

1. Income Tax on rental profits
2. Capital Gains Tax if you sell
3. Stamp Duty Land Tax on future purchases
4. Repairs versus improvements
5. Record keeping for Making Tax Digital
6. Whether company ownership is worth exploring
7. How property income interacts with your other income

FHP’s article on Section 24 and mortgage interest is useful if finance costs are affecting your tax position. Their guide to deductible expenses for landlords also helps explain which costs may be allowable and which may be capital in nature.

If you are considering selling, remember that Capital Gains Tax on UK residential property generally needs to be reported and paid within 60 days of completion where tax is due. That is not something to leave until your next Self Assessment deadline.

How to decide which properties to keep, refinance or sell

A sensible review should look at more than gross rent.

Here is a practical way to compare properties in your portfolio.

This sort of review is especially useful if you work with tax accountant property support, because tax can completely change the answer.

A property that looks weak before tax might still be worth keeping if it has strong capital growth potential. A property that looks profitable before tax might be less attractive once finance cost restrictions, repairs and compliance costs are included.

Limited company ownership and SPV questions

Some landlords are looking again at limited company ownership or special purpose vehicles.

Company ownership can sometimes make sense because mortgage interest is usually treated differently for companies than for individuals. However, that does not mean transferring personally owned property into a company is automatically tax efficient.

You may need to consider:

1. Stamp Duty Land Tax on transfer
2. Capital Gains Tax
3. Mortgage availability and rates
4. Legal costs
5. Corporation Tax
6. Dividend Tax when extracting profits
7. Lender requirements
8. Long-term succession planning

FHP’s article on incorporation or transfer to an SPV is a useful starting point if you are weighing up this route.

For larger portfolios, commercial property accounting may also be relevant where your structure includes commercial units, mixed-use sites or more complex management reporting.

Why better bookkeeping matters more in 2026

In a higher-rate environment, poor records become expensive.

If your bookkeeping is months behind, you may not notice that a property has stopped producing real profit. You may also struggle to prepare for refinancing, quarterly reporting or year-end tax planning.

Clean records help you see:

1. Which property generates the strongest net profit
2. Which tenants or units create payment issues
3. Which repairs are recurring
4. Which costs are tax deductible
5. Whether mortgage changes have damaged cash flow
6. How much tax reserve you should hold
7. Whether you can afford future improvements

This is where bookkeepers in Nottingham can help, especially if you want your property records updated regularly rather than reconstructed at the end of the year.

If you are still using spreadsheets, FHP’s guide on From Spreadsheets To Xero is useful. Their bookkeeping health check can also help you spot weak processes before they become bigger problems.

Making Tax Digital is now part of the landlord conversation

Making Tax Digital for Income Tax now matters for many landlords and sole traders.

From 6 April 2026, landlords and sole traders with qualifying income over £50,000 must use MTD for Income Tax. Qualifying income usually means gross income from property and self-employment before expenses.

That means a landlord with £35,000 of rental income and £18,000 of sole trader income may be within scope because the combined qualifying income is £53,000.

This is one reason landlords are moving to cloud accounting and more regular record keeping. Quarterly updates do not mean quarterly Income Tax payments, but they do mean you need cleaner records during the year.

Helpful related guides include:

1. Making Tax Digital for Income Tax
2. MTD quarterly reporting
3. Making Tax Digital for landlords
4. Making Tax Digital quarterly update returns
5. Making Tax Digital jointly owned property

If you want software support, xero accountants Nottingham can help you build a system that works for rental income, expenses, quarterly updates and management reporting.

Renters’ Rights Act changes and cash flow planning

The Renters’ Rights Act has changed the way landlords need to think about risk.

From 1 May 2026, Section 21 no-fault evictions ended for new notices in England. Landlords now need to rely on valid possession grounds. Rent increases are also more controlled, and landlords need to follow the correct process.

For your finances, this means you should allow more room for:

1. Longer dispute periods
2. Possible rent arrears
3. Higher compliance administration
4. More detailed tenant documentation
5. Legal or professional support
6. Voids that take longer to resolve

This does not mean you should panic. It means your cash flow forecast needs to be more realistic.

FHP’s guide to filing returns for landlords can help with the reporting side, while landlord cash flow mastery is useful if you want to strengthen your reserves.

Commercial and residential property management accounts

If you manage property for others, or your portfolio includes service charge responsibilities, your accounting needs can become much more detailed.

You may need to separate:

1. Rent
2. Service charges
3. Tenant deposits
4. Management fees
5. Repairs
6. Reserve funds
7. Client money
8. VAT
9. Supplier payments

This is where accounting for property management becomes important. FHP’s guides on tenant deposit accounting for commercial property, common service charge mistakes and apportionment methods explained are all relevant if your property finances involve shared costs or managed buildings.

For residential blocks, accountants right to manage services can help directors, managing agents and property managers keep accounts clearer and more compliant.

Practical steps landlords should take now

If you have not reviewed your buy-to-let finances recently, May 2026 is a good time to do it.

Start with these steps:

1. List every property, mortgage rate, lender and product expiry date
2. Calculate net monthly cash flow after mortgage, insurance, repairs and management costs
3. Compare gross yield and net yield for each property
4. Review whether rent is still aligned with the local market
5. Check whether any rent increase must follow the correct Renters’ Rights Act process
6. Separate repair costs from improvement costs
7. Review whether any sale could trigger Capital Gains Tax
8. Build a tax reserve based on current profits, not last year’s guess
9. Move records into digital software if MTD applies or may apply soon
10. Speak to a property-focused accountant before restructuring

You may also want to read FHP’s article on capital allowances on property if your portfolio includes commercial property, fixtures or more substantial works.

If your property income sits alongside a business or new venture, an accountant for start up can also help you avoid mixing personal, business and property records.

For larger operations, outsourced finance services may be a better fit than occasional year-end support, especially if you need regular reporting, forecasting and decision-making data.

FAQs

Should landlords fix their buy-to-let mortgage in 2026?

A fixed rate can be useful if you want certainty over monthly payments, especially while interest rates and lender pricing remain volatile. It may not always be the cheapest option, but it can make cash flow planning easier. You should compare the rate, fees, early repayment charges and your expected holding period before deciding.

Is buy-to-let still profitable in 2026?

Buy-to-let can still be profitable, but the margin depends heavily on location, debt level, tax position, repair costs and tenant demand. You should look at net profit after mortgage costs, tax, insurance, maintenance and void periods rather than relying on gross rent alone.

Should I sell a weak buy-to-let property?

You should review the numbers before deciding. A sale may make sense if the property has weak yield, high repairs, poor tenant demand or heavy refinancing pressure. However, you also need to factor in Capital Gains Tax, selling fees, mortgage penalties and whether the released capital could be used more effectively elsewhere.

Does Making Tax Digital affect landlords?

Yes, if you are an individual landlord and your qualifying income from property and self-employment is over the relevant threshold. From 6 April 2026, the threshold is over £50,000. It falls to over £30,000 from April 2027 and over £20,000 from April 2028. Limited company landlords are not brought into MTD for Income Tax in the same way.

Why work with a property specialist accountant?

A property specialist accountant can help you understand rental profits, mortgage interest restrictions, Capital Gains Tax, ownership structures, MTD reporting, service charge accounting and portfolio cash flow. This is especially valuable when you are refinancing, restructuring, selling or expanding.
