Quote from @Enrique Toledo-Perez:
I'm a Realtor and I'm wanting to get into fix and flips by working with wholesalers and buying properties in neighborhoods with a good spread. I'm having trouble determining who's a good wholesaler and who's not. What are ways to determine who's a good wholesaler, and what should I be analyzing to determine if a neighborhood/area is good to invest in?
Just like you would as a realtor, use your marketing techniques (cold calling, mailers, networking etc.) to find good off market deals for yourself. Just be transparent with the sellers that you are licensed and for good grace recommend they use a realtor on their end, although not necessary.
However, in my experience the good wholesalers understand comps and construction costs, are transparent, have good referrals, and can actually get you in the property.
As a realtor, you'll be the boots on the ground. Sign up for local news articles, go to events in different areas, attend neighborhood association meetings, and just go out and have fun. Try new restaurants, entertainment venues etc and you'll have a pulse on what's going on in your area.
