The White Coat Investor is the best resource to learn about doctor loans and other financial tips. Jim Dahle, the man behind the White Coat Investor, is an emergency physician whose other passions include investing and personal finance. One topic that he heavily discusses on his website is the concept of doctor loans. A doctor mortgage loan has a high interest rate, but a much smaller down payment than traditional loans. An advantage of this type of loan is that a resident, fellow, or doctor can provide a signed job contract instead of paystubs, which will allow them to close on the loan before actually starting work. This can be appealing to those looking to purchase a home in the new area they are moving to for a new position. The White Coat Investor has broken down where doctor loans are available in each state making the process easier for those who are interested.
