I'm glad this was brought up because it raises a topic that's near and dear to my heart.
As far as this one deal - it closed and if there's anything that basic physics can teach you it's that what works once, can work again. You simply decide if you want to do it again. Personally I decided not to.
I actually avoid bird dogging, property scouting, and wholesaling in general. I only do them when I need to. Why? It's not true Real Estate Investing, as Ryan said. It's being a Real Estate Entrepreneur - a self employed one (what side of the quadrant is that again?). It's merely marketed as Real Estate Investing because that terms sells educational courses better than entrepreneur. Entrepreneur has a risky sound to it and for good reason.
An investor invests capital for a return. Bird dogs, property scouts, wholesalers etc. generally don't have the capital to invest - thus they do these deal chasing activities. An entrepreneur gathers resources to create value. That's what bird dogging, property scouting, wholesaling is - gathering property, information and investors to make a deal happen. Each of these activities is a singular event leading to a singular payout. None of it is passive income.
Why do you think so many new "investors" are having such a tough time in this current market? They're trying to act like "investors" when they need to be acting like "entrepreneurs". You couple that with the naturally low success rate of entrepreneurs and your bound to get the nonsense we see now. Can't put the cart before the horse unless fate provides you a windfall.
Here's the worst case scenario of this - I had a wonderful gal I was teaching basic cashflow investing to. She's a well paid software programmer who left a near 6 figure job to become a full time bird dogger because someone told her she should be a full time investor and couldn't figure out why it wasn't working out. I explained to her that she didn't escape the rat race. She went from an excellent job to being self-employed....or rather glamourously unemployed. She escaped the software programming rat race for the self employed real estate rat race....and she didn't even like bird dogging! She preferred programming! But she listened to somebody who told her to be a "full time investor" and drank the Kool Aid. I then explained to her that she could be both an employee and an investor and grow her passive income - and truly exit the rat race on truly passive income that exceeded her expenses. The look in her eyes when she realized that her job wasn't necessarily a bad thing that she should be ashamed for having was priceless. Did I sell a bird dogging educational course? No. Did I sell anything - yeah, $100 of training (but I paid for lunch and gas so it came out to $60...lol). Did I do the right thing? Absolutely.
Remember what Rich Dad taugh Robert Kiyosaki - make your money in business; hold your money in real estate. I doesn't matter if you make your money bird dogging, making toothpicks, contracting, or selling Prepaid Legal. These are all entrepreneurial pursuits - make money there. Invest (hold) your money in real estate investing. True real estate investing is investing earned capital for a return - buying cashflowing property, holding private notes (not brokering them), whatever it is you do.
