I’m Charles Calvert, a mortgage broker at Easy Mortgages. This is general information, not personal advice. Always check the figures against your own situation before you decide anything.
Buy to let in Portsmouth? Investors usually ask about deposits, rental cover rules and whether a personal name or limited-company application fits better. Portsmouth’s mix of professionals, students and naval-linked demand creates opportunities — and criteria traps if you pick the wrong product type.
As of late August 2024, landlord lending still hinges on deposit size, rental stress tests and your wider credit picture. Product pricing moves with the wider mortgage market; criteria detail matters as much as the headline rate.
Deposits and LTV
Many buy-to-let lenders still look for deposits around 25% for standard cases, with sharper rates often available for larger deposits. First-time landlords sometimes face tougher maximum LTVs than experienced landlords. Your own residential mortgage and credit profile still matter.
If you are raising a deposit from remortgaging your own home, that is a separate residential application with its own affordability test — we need to sequence both cleanly.
Rental stress tests
Lenders check that expected rent covers a stressed interest rate by a set percentage (interest coverage ratio). The exact test depends on the lender and your tax position. Optimistic Rightmove screenshots are not enough — underwriters use their own valuation of rent.
Higher stressed rates in recent years have reduced maximum loans for some landlords compared with the ultra-low-rate period. Running the numbers before you bid on a Portsmouth terrace saves aborted legal fees.
Standard AST vs HMO
A straightforward single-family AST is the path most Portsmouth first-time landlords start on. Houses in multiple occupation (HMOs) and larger student lets often need specialist lenders, licences and different stress tests. Treat forum tips about “easy HMO yields” cautiously until criteria and licensing are checked.
Limited company mention
Some landlords prefer a limited company for tax or portfolio reasons. Company applications use different affordability tests and usually need accountant-prepared figures. Whether that suits you is a tax and lending conversation — I cover the mortgage side; your accountant covers the tax side.
Next step
Share the property link, expected rent, deposit source and whether you already own a home. I will outline realistic lender routes before you commit to costs. Fees depend on the case type; I will confirm them up front before any application. Specialist cases are £895 on full offer where that route applies; standard purchase fees are £495 on offer.
Personal name vs company — practical mortgage notes
Personal applications can be quicker when your tax position is simple and the lender’s ICR works on your higher-rate tax assumption. Company applications can suit landlords building a portfolio, but accounts, accountants’ letters and personal guarantees often appear. Neither route is automatically cheaper on rate.
If you already hold several mortgages, portfolio landlord underwriting can apply even on a Portsmouth purchase that looks like a one-off. Declare the full picture early.
Tenant and void assumptions
Stress tests use stressed interest cover, not your optimistic net yield spreadsheet. Void periods, agency fees and maintenance still sit in your real-world cash flow even when the lender’s ICR passes. Borrow for the stressed test; budget for the real year.
