There is no much who offer, but yes there is and it is possible Some Doman Registrar’s offer’s a loan and have your Domain as collateral, But usually, the loan amount will be credited to your account in their platform and must also be spent on the platform fro buying Domain names and other services.
Having a Domain name on a Registrar is a good thing especially if you have a Domain name that you want to register or buy but you run out of budget.
Epik.com is a Registrar famous in giving this kind of service, You can apply for a Domain loan on their platform and choose a payment term, But the loan amount will be decided by them, but that’s not a big deal if you have a Premium Domain and if not you might need to use more than one Domain name as your collateral to get your desired loan.
I haven’t tried but I’m sure there are banks who can approve a personal loan and use a Domain name as a Collateral, but again it should be a Premium Domain name.
A Domain name is an Asset especially if you know what to do with it, Sell it, Flip it, Rent it, or Develop there is always a high chance of making a profit from your Domain names.
