How Can I start wholesaling while still in High School?

[Hector Rivas]

I'm 18 years old and I know vaguely about wholesaling but I want to know what's the most efficient way to get leads without wasting much capital. I'm think on starting on to obtain government listing (pre-foreclosure, tax liens, water shut off, etc) and also probably call or text Real Estate Agents on listings they might have that aren't on the MLS. Many people talk about MAO formula but they don't talk about how to calculate the repairs. What has been the most efficient and best ways you guys have been able to calculate Repairs on a property?
