This was an interesting thread. I rarely can contribute to this forum as I know nothing about internet marketing - but Real Estate - I know.
1. There are $25K-$50K houses in many markets that will get you the $750 per month. Even California. I just sold one of my homes in Fresno for $40K and it had same $750 tenant for 6 years before I bought it for $20K.
2. If you have money for down payment acquiring a loan for a rental is easy.
3. Rusky had it right - short sales is where the market is right now. Want to make close to a million? 20 closed leads per month for next 24 months at $2,000 per closed deal = $960,000. That's it. Just switch those Loan Mod campaigns to a salesperson that can turn the lead into a short sale. (yes, we pay this much and more - so don't tell me you cannot get this much per deal) - the difference is you are getting paid when the deal is done - not just for the cold lead.
4. Fix and Flip - too risky and time consuming unless you know what you are doing. Yes you can put in $30K (down on the loan) and pull out $60K (net proceeds after sale) in 90-120 days - but it's very hard to scale up to anything worthwhile.
