@Ashley Zhang There are definitely other strategies besides "driving for dollars" that can give you good results.Targeting demographics - buy a list of properties of elderly owners (60+ years of age), who do not live in the property and have owned it for at least 10 years;For sale by owners (Zillow, Craigslist, FSBO.com, etc.) - even if you can get them down a few thousands you can assign the contract for a fee - a lot of FSBOs do not know how to market or sell their properties;MLS - you can use the MLS to locate properties to wholesale or flip, but you have to do it a certain way, which can be harder for a beginner;and several others, but this is a start for you.
