When we bought our home several years ago, our realtor found a good mortgage company for us to deal with.  They guided us through the process and explained everything to us.  They made signing the contract and all the paperwork as efficient as possible.  People looking for mortgages want the best deal they can find and want cheap mortgages. Some people want buy to let mortgages with the purpose of renting out the properties.  Whatever the purpose for buying a house, everyone wants the best deal they can find on the interest rate and on the closing costs for purchasing the property.  That’s why it is good to shop around and compare companies.
