I gathered this data from looking at rooms vs home rental prices on CL. 

Damn.Definitely get yourself some agent help so you can get good property data next time.

Simply put: Based upon research I have conducted using the Multiple Listing Service, the data does not support your claims. 

I am also interested in any affordable properties in Dignowity Hill for future flips (I know this is a HOT area but I've driven by and seen for sale signs).

I also found a source that stated that Creative investing is much more stable than Traditional because Traditional investors now more than ever have much more competition because of Hedge Funds and other institutions that heavily invest in real estate while the Creative approach is driven only by motivated sellers. 

Keep the forms spreadsheets so you have a second record of your data.

This is probably primarily driven by our lack of inventory, which many markets across the nation are experiencing. 

I compile the data myself from various sources.

City-data is a good source.

I'm excited to meet motivated, driven, fun people interested in real estate.
