I charge $600 a week for a 3 bedroom house that costs a 4 digit number to buy and a 3 digit number to furnish. 

The key word will be underpinning for you if you have to dig, it's a pain but you are going to live there, do it.  

Retirement plans are best suited for lending.On a positive note, it's not a difficult business to learn and earn double digit returns with very little risk, if you're careful.

Couple hundred dollars cash flow, and double digit ROI.

I buy mine from Multifamily NW (they have digital signing built in, and after the initial fee the annual subscription for unlimited use of the forms is under $50 for 5 or fewer units).You might also consider getting your lease from the local landlord association.

Some may recommend parking it in the stock market, which could get you higher yield. but also opens you to double digit loss.

Whose face will he be giving the single digit to when things don't go well?

We digitally staged our last 2 houses and that was a nice balance.

The latter I use to scan documents with my phone's camera along with keeping digital copies of everything.The only paper that I have is building plans and a notebook I use to scratch notes into. 

Digital ..yes...maybe tied to USD or Euro or Swiss Franc.....too many shams with BTC to make it legit.
