You can use a buy to let remortgage to refinance the original mortgage and benefit from more advantageous interest rates and payment guidelines, or to finance an additional property when someone is looking to expand their property ownership.

While being able to find a buy to let mortgage is not as simple as it use to be, there are still several lenders who are willing to give them if the credit score is high enough for that property owner. If the property is currently rented and the owner can show proof of the income it generates, that will make it easier to obtain the loan.

Repayment guidelines for buy to let remortgages can be designed so that the owner only has to pay the interest due each month, or as a complete repayment loan instead. Which terms work best for the owner varies from one property owner to another and one portfolio to another.

In general, the key criteria that banks look at when making a decision on a buy to let remortgage is whether or not the property can produce income equal to 125 percent or more of the interest that will be due on the loan each month. If the answer to that question is yes, the approval of the loan is most likely.

Using a buy to let remortgage to fund the purchase of another property can be a smart business decision. Therefore, the property that already has a mortgage is still the only one being risked if problems arise with making payments on the loan. It is also easier to handle a single loan payment each month than to worry about separate payments for separate properties.

The real advantage to having a buy to let mortgage or remortgage is that the income from the property is expected to be sufficient to cover the bulk of the payments. Depending on what one does for a living, other sources of income may not necessarily be enough to even come close on loans for properties of any size.

Be prepared for the fact that finding a buy to let remortgage may end up taking some time and effort on your part as a property owner. However, making that effort is worthwhile if you want to refinance your current buy to let mortgage to be able to take advantage of a change in terms or finance a new purchase without risking the new property. It might be more simple to obtain a buy to let remortgage for a purchase than to acquire the first mortgage on the new property as well.
