Some people are looking for a buy to let remortgage.  The requirements of the mortagage lender will be very similar whether you are applying for a buy to let mortgage or remortgage.  Things like credit scoring (if the particular lender uses this type of system in their business, as many do), debt to income analysis and an overview of the loan to value will assist the financial provider in deciding upon the viability of the buy to let remortgage.

The rational for wanting a buy to let remortgage is simple.  Once you buy a property and generate an income from it as a buy to let, over time, usually the property will appreciate in value.  This means you then have equity in the property.  Many buy to let investors will realise this, and in order to allow them to grow their portfolio of properties, they will remortgage the buy to let and thus release the equity that has built up and use this capital to grow more properties in the buy to let market. 

A buy to let investor has usually the main intention of growing a profitable number of premises – either commercial business buy to let buildings or domestic home properties for families, or students etc.  This will then generate monthly rental income which is used to repay the mortgage that was initially borrowed in order to fund the purchase of the house or building.

This is usually repeated on each property or leased house that they have in order to grow more investments and income in their property portfolio, and a buy to let remortgage allows them to do this.
