Annette, you're likely to get a bunch of responses to this one. Some pro-wholesaling and some against it. The wholesalers and the folks who provide a service around the wholesaling business will all be Pro-wholesaling. While the investors that have gotten screwed on deals will obviously be Anti-wholesaling.
Wholesaling is a way for an individual to basically broker a real estate transaction without being licensed. Depending on the state, it is borderline legal. It started out harmlessly enough,where wholesalers were finding properties, usually distressed, and marking them up comparable to a real estate commissions and selling them to investors who would invest their own money, sweat equity, and time to turn the property for a profit. That's back when it was more simple and the name "wholesaler" didn't have the same connotation as root canal or colonoscopy. Today, things are a bit different.
So, while conceptually wholesaling can be a good thing. You know...the whole helping people on both ends of the deal...thing. It can also be a bad thing when you try to out profit the folks investing their money, time, sweat and tears, into a property. Some may say that capitalism for ya. But other may say it's just bad business. I've purchased properties from several wholesalers, both big and small. So, I speak from experience on this matter. I prefer to deal with smaller wholesalers as they are not quite as "profit driven" and tend to be more honest with there estimations on things like ARVs and rehab costs. I hope you become one of those wholesalers.
Hope this helps. Good luck to you as you move forward.
