With a buy-to-let you can borrow up to 75% of the property value. The mortgage amount is then dependant generally on two things: Anticipated rental income and your tax band.

Being in a higher tax bracket will mean you can borrow less this only applies for those looking to purchase in their personal name.

Lender will then assess the rental income in connection to the property value to see if it passes their ICR ( Income Cover Ratio ) which is a stress test that they use to see if the rent is high enough.

Interest Only mortgages have for a long time been popular with Buy-to-let Investors. The lower monthly repayment can allow Landlords to generate cash flow each month which can then be used to build a deposit for another property purchase. Inflation will overtime erode the loan amount and Landlords will benefits from the assumed increase in property value.

Repayment Mortgages don't offer as much surplus cash flow each month but are still a fantastic option. Slowly building equity in the property each month is a fantastic way to generate capital. Both options make sense, but are dependant on your personal circumstances.

Compared to a residential mortgage buy-to-let mortgages are generally higher in interest rates and in fees. This is due to the risk associated with the type of borrowing. Buy-to-let Mortgages Inherently have a higher risk for lenders due to the fact that it is not the borrowers main residence, and due to tenants not paying their rent.

Borrowing through a limited company is eve more expensive compared to a buy-to-let in personal name and residential mortgage, for the same reasons above.

This depends entirely on each individuals circumstances and we would always recommend independent tax advice, if I need click here.

Borrowing through a limited company is more expensive than borrowing in ones personal name and will generally have higher product fees. Having a limited company will involve set up costs and on going accountancy fees. The greatest benefit of borrowing in a Limited Company is because you can deduct interest payments as a tax expense, reducing your tax bill.

Borrowing in your personal name, could mean better rates, less fees but could also result in you paying more in tax if it changes your tax rate. For example if someone had an Income of £35,000 from their employment, and then had a rental income of £20,000 their total income would be £55,000 moving them from a basic rate tax payer paying 20% to a higher rate tax payer paying 40%, a huge difference.
