Difference between a mortgage and buy-to-let in UK
In my experience buy-to-let mortgages charge a higher rate of interest than an personal residential mortgage.  They are regarded as a business enterprise and presumably the banks calculate that they carry a higher risk.  A bank would probably take action if the property on an ordinary mortgage was rented out, as you would be breaking their terms.  Policies could be rendered void.  The terms on an ordinary mortgage disallow renting out the property.
