Start with the legal name on the offer
A mortgage rate is only one part of a deal, and the other part is the firm sitting on the other side of it. The name printed on an advert and the name that appears on an offer document are not always the same, and the difference matters the moment you query a fee or make a complaint.
1822direkt trades under a short, memorable name, but the binding company is 1822direkt Gesellschaft der Frankfurter Sparkasse mbH, which sits in the DE market and has been trading since 1996. ActivoBank is registered as Banco ActivoBank, S.A. and dates back to 1994. Alinma is Alinma Bank (a Saudi Joint Stock Company), a Saudi joint stock company founded in 2006.
You can check that legal line in the 1822direkt review and the ActivoBank review, then look for the same detail on any quote or agreement you are sent. If the name on the document does not match the name you were marketing, ask who is the lender before you sign anything.
Where the lender is based, and for how long
The home market of a lender shapes the product you are offered: the currency you borrow in, the property types that get accepted, the valuation and legal conventions, and the complaint route if something goes wrong. A lender working in its own market usually knows its rules well, while a cross-border lender may be working from a playbook.
Alinma is headquartered in SA and offers support by email and phone. ARUHI is SBI ARUHI Corporation, based in JP and founded in 2000. Axos Bank was founded in 2000 and is headquartered in US.
Elsewhere the picture varies. Aldermore is Aldermore Bank PLC in GB. Alterna Bank is Alterna Bank, based in CA. Arion Bank is Arion banki hf. in IS, and atHome Finance is atHome Finance S.a r.l. in LU. Compare that spread in the Alinma review, the Arion Bank review and the atHome Finance review.
The licences worth checking
A licence is the quickest way to confirm that a firm is allowed to lend, and that a named regulator stands behind it. What the registration means differs by market, so read the entry rather than assuming it matches another country's scheme.
ActivoBank lists its Banco de Portugal licence as 23, and it also holds a separate registration with the Autoridade de Supervisao de Seguros e Fundos de Pensoes, given as 419501226. In the UK, Aldermore is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the PRA, under 204503.
ARUHI carries a Kanto Local Finance Bureau registration, 貸金業者登録番号 関東財務局長(4)第01512号. A credit intermediary registration in Japan, a bank licence in Portugal and an authorisation in the UK are different things, so a lender working across markets may show more than one. Put the reference numbers you find on each entry next to the licence numbers in the lender's own paperwork.
Fees: where the real cost hides
Headline rates look remarkably similar across lenders, which is why the fee line often decides which mortgage is actually cheaper. The costs worth listing are the arrangement or product fee charged to set the loan up, the valuation and legal costs, the cost of any add-on cover, the charge for repaying early, and the fee for overpaying if you are allowed to overpay at all.
Two lenders quoting the same rate can end up very differently over the life of a loan, so compare the interest rate and the fee side by side rather than ranking on rate alone. A useful shortcut is to spread the upfront fee across the amount borrowed and the number of years you expect to hold the loan, then add it to the interest you expect to pay.
The mortgages ranking is a sensible place to start narrowing the field, and the same total-cost thinking applies if your borrowing is secured against the home instead, as in home equity loans and HELOCs or Equity release. Before you apply, ask each lender for the full fee list in writing, including early repayment terms, so the numbers sit next to each other.
How the account is run day to day
A mortgage is a long relationship, so the support on offer is part of the product rather than a detail. A lender that answers by phone, email, chat and a self-serve help centre gives you both a person to call and a written record of what was agreed, which is useful if a payment date or an arrangement is disputed later.
The ranges are wide. Aldermore offers phone and help centre, and ActivoBank offers phone and help centre. Alterna Bank offers email, chat and phone, while Arion Bank offers email, chat and phone and atHome Finance offers email, chat and phone, which also adds a community channel. Aven offers help centre and phone.
ARUHI is narrower by design, listing chat, and 1822direkt offers email, phone and help centre. For a loan that will run for years, weigh the channel list against how much of the relationship you expect to manage yourself.
A short check before you apply
Work through the same order every time. First, confirm the legal entity on the offer matches the brand you researched. Second, find the licence or registration and note the regulator. Third, note the home market and whether the property type and currency suit you. Fourth, get the full fee list, including early repayment and overpayment terms, in writing. Fifth, check the support channels and think about who you will deal with during an interest rate change.
None of this takes long, and it is far cheaper than discovering a mismatch after a valuation has been paid for. Run the same list across every quote on your shortlist, then read the reviews of the lenders that survive it, where the account details behind the advert are set out in more depth.
