Based on the monthly rent, how much will we lend...

Use this calculator for a guide on how much we could lend your client as a Buy To Let mortgage.  Based on the monthly rental achieved for their property we'll give you an indication of how much they could borrow.  The gross monthly rental will be subject to comment from the Valuer.

What is the Monthly Rent?

What is the Interest Rate?

Your client can supplement the monthly rent using our "Top Slice" option

We are able to offer 'top slicing' if the monthly rental income will not cover the loan amount. This means we'll assess the case based on your clients income and commitments as well as the monthly rental income. Where there is a rental shortfall, your client can make up the shortfall using other income subject to the following:

  • Minimum of 85% of the required rental must be serviced by the Buy to Let property in question.
  • Applicant must be a home owner with good conduct on residential mortgage.  If this is mortgage free, please refer.
  • Full Income verification is required.
  • All borrowing (secured & unsecured) must be declared and will be used as part of the Income Multiple / Affordability calculations - based on £20k income after deduction of other regular commitments.
  • The rental shortfall can be made up by an amount equal to (but not greater than) the difference between the applicants’ residential mortgage and the amount calculated as 4+1 or 3.25 x joint income multiple (3.5 x if joint income exceeds £35,000).
  • Maximum LTV ratio is 80%.
