Asking in the correct forum will get a better response.Read the RULES!

@Brandon Croucier That isn't correct... state laws allow you to enter the property within certain time periods, normally 24 hrs, with or without permission.

The key rules are as follows:1) Syndicator MUST have significant skin in the game, including 10% of the money raised in the first deal, 8% of the second, and 3% of the third2) The only fees allowed are 5% of revenue for property / asset management, which is enough to put food on the table, but not incentivize people to just buy, buy, buy3) The only compensation is 20% of the profit (less on the first 2 deals)4) Rapid acquisition is not allowed. 5% Is minus all operating cost correct ? 

In general, i think Stuart is correct.  

Is this a common method or not?
