How To Build a Property Portfolio in UK?

Owning profitable properties is great, and even a trademark of a successful investor. 

The average UK landlord owns 6-12 properties. This is even higher for London and South West, with 11.6 and 6.4 properties respectively.

However, it’s important to also keep in mind that it’s not just about how many properties you own. More than 50% of UK landlords now treat this task—of managing their property portfolio— as a full-time career.

The main focus of building your portfolio must be to continuously grow your investments. In this guide, let’s learn how you can build your portfolio, from a normal to a high-value collection of asset base.

What is a property portfolio? 

A property portfolio is a collection of real-estate properties managed or owned by an investor. This collection includes properties like houses, commercial buildings, land, apartments, and more. 

The main aim of a property portfolio is to provide a clear view of an investor’s sources of income from various assets. This enables them to track their asset performance to manage and grow wealth. 

Apart from these, property portfolio helps with other functions such as:

• Diversifying risk 
• Identifying tax deduction opportunities 
• Developing investment strategies 
• Utilising loans or property financing 

What does a property portfolio look like?

A property portfolio is a careful selection of real estate investments with important information about them. These are typically stored in property management software, digital tools, or firms that handle end-to-end portfolio management.

For example, you may own or invest in HMOs, buy-to-lets, or residential properties in various locations across the UK. The portfolio will have detailed financial records of each property, such as:

• Income 
• Expenses 
• Mortgage payments 
• Property value 
• Taxes 

It will also include some important legal documentation, tenancy agreements, insurance, and contracts. 

This information shows a clear view of cash flows from each property and how your portfolio is performing overall. It also includes net profits, costs, rental yields, ROI, capital growth, and so on. 

Consider a landlord called Eric who owns two residential flats in London, a student housing property in Manchester, a commercial space in Birmingham, and a holiday rental cottage in Cornwall. 

For Eric, managing his portfolio means to balance different tenant needs, keeping up with new UK regulations, and handling property expenses and income. Now, Eric can opt for simple tools, like Excel, to manage his portfolio himself, but as the number of properties under him increase, he’ll have to look for a more efficient system.

An example of how a property portfolio will look like on a software and Excel:

How long does it take to build a property portfolio? 

It takes 12 months to 7 years to build a property portfolio. The process of buying a property itself takes time, from 3 to 12 months. 

When you’re starting small, it may take around 2-3 years to build your property portfolio. However, when you scale to a mid-sized or a large portfolio, it can take 4-7 years or even more. 

This timeline changes depending on key factors like:

• Available capital 
• Financing options and mortgage terms 
• Market conditions 
• Investment strategy (short-term gains or long-term appreciation)
• Risk

One way to speed up this process is to reduce the time taken to buy property. You can either find off-market properties or reach out to Pluxa Properties to find properties that currently have the potential to give you high yields.

How to Build a Property portfolio with £20k?

With £20k, you may find difficulty in purchasing properties in high-demand areas like London or the South East, where prices can exceed £300,000 easily. Fortunately, you can still build a good property portfolio by following these steps:

1. Research high-yield postcodes and affordable locations

Focus on areas outside the most expensive regions. Aim for locations with higher rental yields but lower property prices. One way to look for these is to use yield maps, Zoopla, or Rightmove. 

For example, you can filter out properties with your budget on Zoopla:

Or you can look for properties that are up for auction:

You can then reach out to local property experts to understand how the area is performing to assess chances of high yields.

2. Make use of buy-to-let mortgages

To increase your funding, you can secure a buy-to-let mortgage. Applying for this mortgage may require a deposit of 25% of the property price. Hence, look for properties that are priced around £80,000-£100,000 using the same method above. 

Consider saving a part of your deposit for costs like stamp duty or legal fees. While you can check out buy-to-let mortgage deposit rates manually, you can also make use of MoneySupermarket. It asks you a few questions before showing a comparison list of buy-to-let mortgages. An example:

3. Look for properties needing light refurbishment (The BRRRR strategy)

While you’re looking for properties, keep it in your checklist to find properties that are underpriced due to cosmetic or light repairs. Property auctions or direct sales are an excellent way to search for such properties. 

Once you purchase, carry out low-cost refurbishments to increase its rentability. Then, either rent out the property or refinance to pull out equity. 

All of the above is the essence of the BRRRR method (Buy, Refurbish, Rent, Refinance, and Repeat). It quickly adds value to your property and recovers your initial investment. 

4. Consider joint ventures for larger investments

You can partner with other investors to pool money and access more profitable properties. For example, if you form a joint venture with one or more investors, you could contribute the £20,000 as your portion of the deposit while your partners provide the rest of the capital.

This way, you won’t have to bear the full cost alone and can even diversify your property portfolio more quickly.

5. Opt for high-cash flow strategies 

Consider HMOs or serviced accommodation which generate higher cash flow than typical single-let properties. 

Invest in HMOs, where you rent out rooms individually to multiple tenants. Serviced accommodations like Airbnb also generate higher rents, especially in popular areas. You can then reinvest these funds in other properties to scale your portfolio.

How to Build a Property portfolio with £100k?

You can build a profitable property portfolio with £100k via these steps:

1. Buy two properties 

Use your £100k to buy two properties in metro areas or regions with strong growth potential. This can offer you neutral or positive cash flow. 

• Use £50,000 for each property purchase 
• Get 75% mortgages for each property (leaves you with 25% of the purchase price as your deposit, £41,250 for each property)
• Target properties priced at £165,000 for good rental yield 

After the first purchase, you’ll own two properties worth £330,000 (or £300,000 to £350,000) with £82,500 of your own capital (£41,250 each), leaving room for other costs.

2. Refinance to extract equity and scale

After 6-12 months, refinance your properties to pull out equity and use the funds to buy additional properties. 

Now, let the properties appreciate with an aim for a 5-10% increase in value. If the market moves favourably, wait until the property grows to £350,000. Refinance both properties at 90% loan-to-value, giving you new loans of £315,000 each. 

The new loans give you an extra £50,000 in cash per property. Utilise the £100,000 to buy two more properties. 

3. Expand portfolio by purchasing more options

You can now use the extracted equity fund from the above. Again, make sure these new properties are under market value with good rental yields. Similarly, target them around £165,000 to £350,000. Make sure the cash flows cover mortgage and other costs.

Finally, move to larger assets to further scale your property portfolio. You can target duplexes or multi-unit properties, providing you with multiple rental incomes. Once you purchase larger assets, continue to use refinancing.

How to Build a Property portfolio with £50k?

Here’s how you can build a property portfolio with £50k:

1. Invest in a multi-unit property

 You can start by purchasing multi-unit property, such as a fourplex. Use a low down payment loan (5% conventional loan), if you’re eligible. With £50,000, this enables you to buy a property up to £1,000,000 in value. 

This strategy maximises rental income as multiple units bring in more rent, covering mortgage costs. Research neighbourhoods to find a ‘B’ or C-related area, where properties are more affordable but still offer a decent rental demand.

2. Use rental income for cash flow and mortgage payment

Rent out all the units, or live in one and rent the others to reduce living costs. In a high-cost area, look for properties that at least break even or provide a small profit – allowing tenants to pay down your mortgage. 

This approach also provides you with tax write-offs and appreciation over time. This grows your investment without extra out-of-pocket expenses.

3. Refinance and scale up

As you build equity, use a cash-out refinance to access capital from the property’s appreciation. Reinvest this capital as a down payment for an additional property, expanding your portfolio. 

As rental income continues to accumulate, consider upgrading to properties in slightly better areas. This enables you to scale your portfolio even further.

How to diversify property portfolio in the UK?

Diversifying your portfolio is one of the most effective strategies of building a property portfolio. It’s a practice where you spread your investments around so that you’re not focusing on just one type of asset. This helps reduce risk and irregularity over time.

1. Diversify by geographic area

First, research UK property markets and focus on cities with economic growth, steady demand, and future capital appreciation. Try to avoid areas that rely on a single industry.

Then, combine high-growth markets like Manchester or Birmingham with stable rental areas. You can also combine metropolitan and suburban properties in your property portfolio. Investing in both city and suburban areas protects you against market downturns if property values drop in one region.

2. Diversify by property type

While you’re at it, include different property types, such as flats, houses, and holiday lets. For instance, suburban houses attract families looking for stability while urban flats offer higher rental yields.

A few other things to keep in mind:

• Balance new and old properties 
• Look for properties which have lower maintenance costs 

Make sure to also diversify your tenants. Invest in properties that attract students, professionals, families, and so on. 

3. Diversify by investment strategy

You can mix long-term rentals with short-term/holidays lets, especially in tourist locations. Purchase undervalued properties, renovate them, and sell at a profit to again reinvest in buy-to-let properties. This is a strategy where you can increase your capital and diversify property income sources.

Lastly, balance income and growth-oriented goals. You can adopt a dual strategy where you:

• Acquire high-yield properties in modest growth areas (consistent cash flow)
• Investing in high-growth locations offering lower yields (capital appreciation)

You can reach out to investment property companies, like Pluxa Properties, which will provide you with insights into high yield locations and property types that align with your investment strategy.

Is it worth building a property portfolio in 2025?

It’s highly worthwhile to build a property portfolio in 2025. Currently, mortgage costs are falling, and will continue so for 15 months. Housing prices are also expected to increase by 4% in 2025 before slightly falling by 0.4%. Non-city areas have a high rise in annual yields as well.

So, if you start researching properties now, you can build a profitable property portfolio in 2025.
