Mortgage Picks for Self-Employed Buyers and Landlords
From 3.54% buy-to-let pricing to £500,000 second-charge borrowing, these mortgage picks fit irregular income and property plans.
Self-employed borrowers, landlords and property renovators rarely fit the neat profile used by generic mortgage lists. Your income may arrive in uneven chunks, your deposit may be tied up in another property, or the loan may need to fund work before a standard mortgage makes sense.
This shortlist separates mainstream residential mortgages from specialist property finance. Santander and Nationwide are the conventional starting points; Molo and Landbay focus on buy-to-let; Roma Finance and Together Money cover bridging and refurbishment; Selina and Central Trust use existing home equity. That distinction matters more than a simple rate ranking.
Rates and terms shown are representative. Your actual rate depends on your credit profile and circumstances. This is not financial advice — always read the lender's terms before applying.
Quick picks by borrowing situation
Best for a standard home purchase: Santander UK Mortgage.
Best for a lower-rate mainstream alternative: Nationwide Building Society Mortgage.
Best for buy-to-let pricing: Molo Finance BTL Mortgage.
Best for substantial home-backed borrowing: Selina Homeowner Loan Second Charge Mortgage.
Standard mortgages when the paperwork is clean
The quoted rates in this group are close: Santander at 4.19% and Nationwide at 4.24%. That 0.05 percentage-point gap is unlikely to decide the application by itself. Affordability rules, loan-to-value, product fees and the size of the mortgage will matter more.
For a self-employed applicant, the practical question is not simply which lender advertises the lower number. It is which lender's evidence requirements match the way income is recorded across tax years. Confirm current criteria with a broker or the lender before submitting a full application.
Santander UK Mortgage
Santander's listed rate is 4.19%, the lowest quoted mainstream rate in this comparison. The official mortgage page covers buying a home and finding a new deal, so it belongs on the shortlist for a standard residential application. The limitation is obvious: the supplied information does not show self-employed income rules, fees or fixed-rate periods, so treat the rate as a starting point rather than a promise.
Santander UK Mortgage
Nationwide Building Society Mortgage
Nationwide quotes 4.24% and explicitly mentions first-time buyers and borrowers switching to a better deal. That makes it a useful comparison against Santander for a conventional purchase or remortgage. The 0.05-point premium is small; the bigger question is whether its affordability assessment accepts your income pattern and property type. Check the current criteria on the official Nationwide mortgage page before applying.
Nationwide Building Society Mortgage
According to the Santander mortgage page, the lender covers both new purchases and switching deals. Nationwide's mortgage page also targets first-time buyers and existing borrowers. Those descriptions are useful, but neither quoted page excerpt gives enough detail to calculate a true total cost, so fees and early-repayment charges still need checking.
That small rate difference should not push you into a lender whose evidence process does not fit your accounts. Specialist property finance becomes more relevant once the property itself, rather than a simple home purchase, drives the application.
For landlords buying or refinancing property
Buy-to-let pricing is led here by Molo at 3.54%, while Landbay provides an intermediary-focused route without a quoted rate in the supplied material. The cheaper headline number is useful, but landlords need to test rental affordability, interest coverage, property type and portfolio rules before comparing rates.
A detail many borrowers miss: both Molo and Landbay's supplied pages are aimed at intermediaries. That means a landlord may need a broker rather than a direct online application. It also means the advertised product range can be more specific than a standard residential mortgage.
Molo Finance BTL Mortgage
Molo's quoted rate of 3.54% is the lowest figure in the full list, but this is not a normal homeowner mortgage. The page states that the website is for intermediary use, so landlords should expect broker-led placement and specialist criteria. It is the first place I would investigate for a buy-to-let borrower focused on pricing, provided the rental calculation and property profile pass.
Molo Finance BTL Mortgage
Landbay BTL Mortgage
Landbay does not provide a rate in the supplied page content, so it cannot be ranked on price here. Its site is built around intermediaries, buy-to-let products, affordability tools and product transfers, which is more useful than a vague promise of flexibility. Landlords with several properties or a refinancing decision may value that broker infrastructure more than a headline rate they cannot yet access.
Landbay BTL Mortgage
Compared with Santander and Nationwide, these two lenders speak the language of rental income and intermediary placement rather than owner-occupier affordability. That makes them more relevant for landlords, but less appropriate for a home you plan to live in. Review the current product details through the Molo Finance site and Landbay's intermediary site before relying on the quoted positioning.
Bridging and refurbishment finance
Bridging loans solve a timing problem, not a long-term mortgage problem. They can help secure a property quickly, fund refurbishment or cover the gap between buying and selling, but the exit plan has to be credible. The quoted rates show why this category needs careful cost modelling: Together Money is listed at 9.96%, far above the mainstream mortgage figures.
Roma Finance does not show a rate in the supplied material, but its RomaFLOW page specifically describes rapid bridging finance. A lower visible rate is not the only measure here; the term, arrangement fee, valuation costs and exit route can change the total substantially.
Roma Finance Renovation Mortgage
Roma Finance's RomaFLOW page describes rapid bridging finance powered by partnerships, but the supplied content does not include an APR, term or fee schedule. That makes it impossible to compare total cost against Together Money from the available data. It belongs on a broker's shortlist for a refurbishment or time-sensitive purchase, provided the refinance, sale or other exit is mapped before borrowing.
Roma Finance Renovation Mortgage
Together Money Bridging Loan
Together Money lists a 9.96% rate and positions its bridging loans for buying before selling, refurbishments and quick purchases. The use cases are clear, but the rate is materially higher than the 4.19% to 4.24% mainstream figures above. I would reserve this for a short, well-defined bridge where speed or timing prevents a standard mortgage, not for a project with an uncertain completion date.
Together Money Bridging Loan
The official Roma Finance RomaFLOW page and Together Money bridging page both describe property timing and refurbishment uses. Ask for the full redemption figure, not just the monthly interest, and confirm whether the lender charges an arrangement fee, exit fee, valuation fee or legal costs. A bridge that lasts longer than planned can become expensive very quickly.
Specialist lending can also help when a standard application is rejected, but “specialist” does not mean cheap. The next group uses existing property equity instead of a short-term bridge.
Using existing home equity
Second-charge and secured loans can release funds without replacing a first mortgage. That can be useful for debt consolidation, a major renovation or a large planned expense, but the security is your property. The monthly payment may look manageable over a long term while the total interest becomes much larger.
Selina lists borrowing from £5,000 to £500,000 at a quoted 5.89%. Central Trust lists £10,000 to £250,000, terms from three to 30 years and funding in as little as three days, with a quoted rate of 9.69%. The gap is large enough to make a full cost comparison essential.
Selina Homeowner Loan Second Charge Mortgage
Selina lists borrowing from £5,000 to £500,000 against a property and shows a quoted rate of 5.89%. That range makes it the stronger starting point for a homeowner needing a substantial second-charge loan, especially for debt consolidation or a large renovation. The rate is still not comparable with a first-charge mortgage until fees, term and total repayment are confirmed, and the property remains at risk if payments fail.
Selina Homeowner Loan Second Charge Mortgage
Central Trust Second Charge Mortgage
Central Trust quotes 9.69%, offers £10,000 to £250,000 and advertises terms from three to 30 years, with possible funding in as little as three days. It also states that it considers all credit histories and accepts employed, self-employed, pension and benefit income, which may matter more than the rate for a borrower outside standard criteria. The long-term option can reduce monthly payments, but it may increase the total cost sharply.

Quick comparison
| Provider | Type | Quoted rate | Borrowing or timing | Best match |
|---|---|---|---|---|
| Santander | Residential mortgage | 4.19% | Purchase or new deal | Standard homebuyer or remortgager |
| Nationwide | Residential mortgage | 4.24% | First-time buyer or switcher | Conventional residential application |
| Molo Finance | Buy-to-let | 3.54% | Intermediary route | Landlord focused on quoted pricing |
| Landbay | Buy-to-let | Not supplied | Intermediary tools and products | Portfolio landlord using a broker |
| Roma Finance | Bridging and refurbishment | Not supplied | Rapid bridging | Time-sensitive renovation or purchase |
| Together Money | Bridging loan | 9.96% | Purchase, sale gap or refurbishment | Short-term funding with a defined exit |
| Selina | Second-charge homeowner loan | 5.89% | £5,000–£500,000 | Large home-backed borrowing |
| Central Trust | Secured homeowner loan | 9.69% | £10,000–£250,000; 3–30 years | Non-standard income or credit history |
Do not compare every number in one column as though these were identical products. A 3.54% buy-to-let rate, a 9.96% bridge and a 5.89% second charge solve different problems and carry different risks.
What to avoid before applying
- Do not chase the lowest headline rate blindly. The cheapest figure may belong to a buy-to-let or intermediary-only product that does not fit your property.
- Do not use bridging finance without an exit plan. A sale, refinance or other repayment route should be realistic before completion.
- Do not ignore fees. Ask about arrangement, valuation, legal, exit and early-repayment charges.
- Do not stretch a secured loan over 30 years just to lower the monthly payment. Calculate the total repayment as well.
- Do not assume self-employed status automatically means specialist finance. Santander or Nationwide may still work if your accounts and affordability evidence meet their criteria.
Final recommendation
For a self-employed buyer purchasing a home to live in, start with Santander and Nationwide, then compare the full offer rather than the 0.05-point rate gap. For landlords, Molo is the rate-led starting point at 3.54%, while Landbay makes more sense when intermediary support and portfolio tools matter. Roma Finance and Together Money belong to short-term property projects with a documented exit, not ordinary home purchases. For homeowners releasing equity, Selina's £5,000–£500,000 range and 5.89% quote deserve attention, while Central Trust is more relevant to borrowers with unusual income or credit histories despite its higher 9.69% rate.
Property finance gets easier to compare once you separate home purchases, buy-to-let, bridging and second-charge borrowing. For a broader guide across those borrower types, read Mortgage Picks for Buyers, Landlords and Homeowners.
