I added a screen around the wood burning stove, a Keurig, and made a little coffe station with K-cups, sugar, creamers, etc.   

I'm not quite sure what you're asking but I'll take a stab at it.I keep all my documents on Google Drive.

If you have little money to work with, then use your time... post ads on Craigslist, attend your local REIA and any other Meetup groups, network, door knock, do Driving for Dollars, hand write and stuff your mailers, etc, etc, etcIf you have the money but not the time, then you pay someone to do the above things.If you have neither the time nor the money you won't make it very far...

That option wouldn't make sense with $8k in closing costs added to the two refis.

You're out whatever money you've wired him and whatever fees your bank charges you.If you want to play along (google scam baiters or look at 419eaters.com), have him send the check.  

There are lots of quantitative metrics ("mainstream" as you say) to observe here (P/E for the S&P - see chart below, margin levels, ratio of total market cap to GDP, etc), & anyone with access to google can see the same numbers.

One idea I had with seller financing is buying rehabs, adding value, and then refinancing out of the seller financing.

If you google search "Genworth PMI quote," "Radian PMI quote," and "National MI PMI quote" you can play around and see the variance, but again FHA is one-size-fits-all right from that gov't chart I linked from HUD.

I can install Google Analytics to measure how much traffic my website is generating, which allows me to then install a code for retargetting ads that will follow that site visitor.

Looking forward to adding your podcast to my list.
