3. Find a good bank or mortgage broker in your area if you’re financing your investments. Realtors (real estate agents who belong to the National Association of Realtors and must adhere to a code of ethics) are good sources for recommendations, or you can ask other investors whom they’ve used. You might want to do this even before you start your property search. If you’re paying cash, you’ll need to prove you have the funds by submitting a recent bank or brokerage statement when you make an offer.
