I currently own 4 houses and would like to expand that to double digits along with possible larger units.

I Currently have double digit number of deals with Patch of Land and Realty Shares and one with iFunding.

Many passive RE investors, hard money lenders, and note buyers seem to be happy with low double digit rates of return, thinking that, relative to stocks, bonds, mutual funds and annuities, mid-teens is a respectable yield.  

There is no other currency that will replace it in the near term.

Basically someone sends that address (a US address) mail and the company will email me and say 'hey you have this mail' (with a screenshot of the letter) and if I want them to open it and scan it I tell them to, and they send me digital images of the content.

I would like to know what the general consensus on digital signatures is, and if you accept them do you have rules on what constitutes a valid signature (ie does typing your name in a blank count, or only cryptographic signatures allowed).

@GregsRe: Internet access Wifi "child porn" actually happened  my sister-in-law she owned and lived in her 4 plex she offered free internet Wifi to her tenants, they had the sign on code,, they passed it on... to somebody...that guy didn't live there but used their wifi account and was a pervert.So mean while,, everybody in the 4 plex had the cops in each unit, they took all hard drives, laptops, even digital cameras as part of investigation. and it was a huge mess.

Might be worth checking out the new tablet apps that allow signatures on digital contracts. 

There are going to be double digit markets that meet this requirement.

Our group has several investors that enjoy double digit returns on their investments.
