It's good you told everyone your story, because if it helps just one person, it has a positive social result. In the past months I have heard numerous stories similar to yours. Also, I have heard of an increase in straight out scams. Some key characteristics to look for with scam artists include: creating a sense of urgency, reinforcing the notion that the offer could be gone forever, creating a sense of friendship and trust (in fact, scam artists usually are close friends, even relatives)
The point is, never give anything up for something that is merely a future promise. If it doesn't exist, its not worth a dime, like Kool-aid. Always do your research. And although I feel bad that you lost $40k, I have heard horror stories of people getting their whole life savings ripped-off. It is sad, but just remember that God knows what is in your heart. If you are indifferent to the truth, God will be indifferent to you.
I completely agree with your assertion that buying, even when you did, was a good idea. Sounds crazy, I know. Let me explain. Rents have been rising, but I project they will fall before stabilizing. The big problem in the future is getting the loan to finance the house. So if you can't buy all cash but can afford a 30 year fixed with 20%, and you get a REALLY good deal on the house, then it is the time to buy. The problem with being all cash is that the dollar may collapse, thereby making your CD's worthless. So in that sense, a house, and even a mortgage, could be a great investment. There is so much uncertainty and the obvious reaction is to hold back. But when you really consider the alternatives, there is no investment better than a real estate. What else are you going to invest in, stocks? no. Bonds? no. cash? useless gold?
It is seldom discussed, but if you do the math for the safest apparent investment in the world, you start to realize how bad and ambiguous it is. A US treasury has a face value of $1000. A year ago, you could buy treasuries at auction for a discount! So a $1000 bond with about 4% return cost about $950 (30 yr). 3 months later, that same bond was selling for around $1200! THATS $200 ABOVE THE FACE VALUE! WTF? Do people really want $40 a year per $1000 that bad? WTF? Really...
