My goal is to use real estate investing to become financially free.

This same user is discussing his strategy in that thread and i'll give you a wild guess as to if it's trading options or not. 

when it comes to buying rental houses in the quote un quote cash flow markets.. these markets are pretty much all interchangeable.. rent rates pretty consistent  with about a 1400 to 1500 cap.. higher than that and most will buy.I think for quick math for out of state folks so they don't get lured into properties that are ONLY appropriate for local tough as nails landlords.. you simply need to look at the median price of the area.. then buy within 10 to 20% of that.. and also only buy were the rent commanded is within 20 to 25% of the top rents in the area.. 

A friend recommended Red Wagon Properties. San Antonio PMC.  Online reviews are decent. Anyone have experiences- good/bad with this PMC?

You can't use "rent credits" because the lease option will be reclassified as a sale and require a foreclosure instead of an eviction if things go bad.You have to use separate lease and option agreements which do not refer to each other.

Next, if your unit is exactly the same as a unit across the street, but he tenants pay water/sewer/trash there, then technically your unit can command higher rent because there are more fees included.
