How much skin in the game is the borrower providing?

Unless there exists some alternative revenue source for a Paperstac-like platform to profit from (beyond transactions) or some amazing value proposition not already provided by Paperstac, it's hard to envision a similar site for smaller players doing well. 

I'm not sure if you will find someone to post about this topic here but you can certainly visit some of the real estate groups close to you (there are several in San Antonio).  

If you want to look for an investor focused brokerage or team in a brokerage I'd recommend looking for meetups in the local area for real estate investors or potentially other investor focused agents in the area, you can likely find both of these with bigger pockets (depending the location).

I have no issues, but I didn't need to provide so much information, even for a conventional loan. 

I consider this a large loss.You may find there is mold in there too. 

How did you find this deal and how did you negotiate it?

I bought our current house in the middle of a harsh winter because we were relocating and need to find a place. 

You are not crazy :) cap rates on storage got pretty crazy in the last decade as the space has become crowded and money was cheap, starting to see some reversal of that now, but its tough to find deals at a true 10 cap (10 x NOI or NOI / .10).

I just find it funny that so many people critique the guy... because that is exactly what he is going for.As far as the $1,000 program is concerned - I'd buy it if I was looking for a motivational, pump me up, get me stoked kind of event.
