Is Buy-to-Let Investment still the right route to Residential Property Investment, or is an HMO a better option? With changing rental yields and regulations, many UK investors are asking this question. Each option comes with different income potential, risks, and workload, depending on your goals, budget, and available time. TRM Property Solutions is a London-based consultancy that identifies residential and commercial investment properties, including multi-let properties. Our team has over 30 years of combined experience in property, development, and refurbishment. This guide compares buy-to-let, HMO, and multi-let options to help you understand the numbers, regulations, and trade-offs involved. Ready to start? Talk to our experts and share your objectives.
What Do Buy-to-Let, HMO, and Multi-Let Mean?
The terms are used loosely, so let’s define them. One for each of them; each explains how you let a property. Income, costs, and rules are dependent on that decision.
- Buy-to-let: one house rented to one family or other household unit
- HMO: a house which is rented to three or more families, each occupying a separate household.
- Multi-let: one building comprising multiple separate lets, for example flats in a block of flats.
Some multi-lets are HMOs. Others are blocks of self-contained flats. The difference is significant in the field of finance and licensing.
How Do Yields Compare?
The very first aspect a good investor will be checking is the yield. The gross yields for the typical buy-to-let property in the UK tend to be in the region of 5% to 6%. Other northern towns go higher. The gross yield of HMO’s is typically 8% to 12%. In the case of multi-unit blocks, this figure is roughly 7% to 10%. Use these as suggestions, NOT guarantees. The higher the costs of HMO, the lower the net yield is, typically two to four points lower than gross. Published figures vary from source to source and are subject to rapid change. Always apply the numbers to actual rents.
| Factor | Buy-to-let | HMO | Multi-let (self-contained units) |
| Typical gross yield | About 5–6% | About 8–12% | About 7–10% |
| Income streams | One rent | One rent per room | One rent per unit |
| Finance | Widest lender choice | Smaller, specialist pool | Often specialist lenders |
| Rules | Lightest | Licensing and planning | Building-wide safety and lease checks |
| Management | Lowest | Highest | Medium |
| Void risk | All or nothing | Spread across rooms | Spread across units |
| Often suits | First-time investors | Hands-on or experienced investors | Investors building scale |
You can choose which rooms to void in or out and which units to spread across, or spread throughout the unit and across rooms, or choose all or nothing.
Buy-to-Let: Simple and Predictable
Buy-to-Let Investment is ideal for investors seeking a low-maintenance, consistent return. Lenders are familiar with the product, so there’s a wide choice and competitive rates. It is easier to manage and has longer tenant retention. The risk weakness is concentration risk. No rent for one month equals no rent at all! It’s not just about the high headline yield; there’s the strong tenant demand, too. Locate homes close to transportation and employment. This will also provide you with a level foundation on which to build before adding layers of complexity.
HMO: Higher Income, Higher Workload
The rules are the starting point for good HMO Property Sourcing; the yield is the outcome. An HMO can generate rent from each room, and the rent that is generated is significantly higher per property. It also distributes the void risk among multiple tenants. You get more rules, more costs, and more management in return. The licensing requirements for HMO’s of two or more households, with 5 or more people, will apply. For HMO’s of 2 or more households, with 5 or more people, licensing will be mandatory.
- Only a smaller number of lenders and higher rates are available for finance.
- Safety and maintenance: fire safety and room requirements; frequent wear
- The cost of licences is often several hundred pounds or more than approx.£1,000. Please check with your local council before making an offer. Regulations vary from place to place. Buying this one hastily can be very expensive.
Multi-Let: Scale Under One Roof
A multi-let building means you have multiple rents on one property. Self-contained flats within one block might be easier to operate than communal rooms. One of the benefits is also that you save time with repairs, because one roof will serve many units. These deals are usually regarded as niche products by the bank. Read the legal title, terms of the lease, and any obligations for the safety of the building.
Which Route Fits Your Goals?
Often, Strong Residential Property Investment involves multiple paths. Beginning players tend to begin on a single let. A Multi-let may be added for experienced investors to add scale. HMO may be a better option for hands-on investors willing to put in a bit more effort. This should be based on your budget, time, and risk tolerance. Our Portfolio Building service is designed to assist you in planning that mixture. We consider your cash flow, your time frame, and your ability to handle the management. Then, it’s a match to your plan, not the other way around. That ensures that all purchases are moving towards the same thing.
Rules That Affect All Three Routes
Review the guidelines before bidding. 10 May 2026 was the end of Section 21, which now becomes periodic tenancies. To regain possession, landlords must have valid Section 8 grounds. There is a 5% stamp duty surcharge for extra houses. Speak to a tax adviser about these rules.
How to Compare an Opportunity Step by Step
Calculate Gross Yield (annual rent/purchase price)
- Calculate net yield: Remove costs, void periods, finance.
- Stress the deal: test the deal with a higher interest rate.
- Review the rules: license, planning, and lease.
- Plan management – management of the property and the exit.
Perform these actions on each deal. A deal that passes all five should be considered. If a deal does not work out, there needs to be a real resolution.
Common Mistakes to Avoid
Many investors ignore the rules and just go for the big yield. Some people don’t remember licensing fees, void periods, and the wear and tear associated with communal properties. Some people take too tight a loan, and if they see a rise in rates, it hurts them. Some purchase beyond their level of competence and have difficulty managing. Most of the errors can be avoided with a clear plan and honest numbers.
Where to Look: London and the North East
Many investors turn elsewhere to London prices for yields, which often are quite tight. Based in London, TRM Property Solutions has recently sold properties in County Durham and Stockton-on-Tees. Those sold at prices from about approx.£50,000 to approx.£115,000. Lows will bring higher yields only where rental demand is there. Please check local council regulations before committing.

Frequently Asked Questions
Does owning an HMO make sense vs. a buy-to-let?
Not always. The advantages of HMOs are that they are likely to pay more, have more rules, and are more managed. Buy-to-let is easier and ideal for investors who are new to the market.
What’s the distinction between an HMO and a multi-let?
An HMO will have common kitchen facilities or shared bathroom facilities between different households. A multi-let may also be separate self-contained flats in a building.
Do I need a licence for an HMO?
The minimum unit size for HMOs for which licensing is mandatory is 5 persons, from two or more houses. There are additional schemes in a few Councils; please check locally.
Are HMO mortgages more expensive than Buy to Let?
They often do. The lender pool is lower, and rates are typically higher. Lenders also have more stringent requirements for rent, and this is where a specialist broker can assist.
Should buy-to-let continue in the UK in 2026?
If the numbers work after taxes, finance, and void periods, it can be. Any changes to the rules in 2026, so test all deals carefully!
