Yes, you can have as many mortgages as you like on as many properties. The issue is that the terms and conditions of residential mortgages expect you to live in the properties as your own home, even if it’s only for a short time, as with a holiday home, for example. In short, it does not matter how many residential properties you buy as long as they are leased and have authentic documentation. If the properties are verified or have missing documentation, you can only buy that residential property.
