I think SFR are the easiest and safest to pursue.

Especially since lenders require "reserves" anyways (given SF Bay Area price points local to me, this can be absurd amounts of money), which can be stocks or index funds -- mortgage #7 may very well require $150k in "reserves," which is your choice of money in a checking account earning you nothing, or index funds that you find appealing anyways.

I recent bought a personal residence in Hamilton County, IN after moving from upstate NY this summer. This entire area is riddled with hard water (I have not had it tested, but judging by my research of the area it is...

Anyway.. its a personal choice.. 

@Tyler Corns I agree with @Jerry Padilla that hard money lenders would be my last choice.

If they have a month or longer to wait, listing on the MLS is the better choice.

The police told us the call to the house was for an OD, and the vile of Narcan left behind helps to narrow down the drug of choice (which I have pictures of-pretty sure you don't pick that up at Rite-Aid). 

For example, I am a little concerned about some aspects of the business cycle recovery and a potential for a double-dip so I lean toward the safest part of capital stack which is debt (or low-debt equity).

You made a great choice.

This is a poor choice of deeds and you should never accept one if you can get a stronger deed.
