I'd like to take this time to schedule a brief call 02/17 at your earliest convenience to delve into more detail as far as how I can quickly analyze and find properties that meet a minimum cap rate.

On top of the previous recommendations - as you don’t appear to have a property manager, I’d suggest you start documenting every issue and correspondence with the tenant.  

Vegas is the conference capital of the world and I'd say Caesars Palace is pretty iconic!

In your case going to a fifth unit as noted above could actually reduce the value, so I'd be cautious of that since that materially degrades their collateral.

If I had enough people to fill a 5 bedroom house I’d definitely want 3.5.

I'd see 1. are there any other grocery stores in the market 2. are there any options on the lease left or is there truly only 6.5 years left 3. does DG want to extend 4. is there already a family dollar in town and if not maybe they'd be willing to take over in this marketIt really just depends on how much work you want to put into buying it. 

I'd look for mortgage brokers in Canada. 

They have been managing fine, although not too busy, I guess because of the market.

The majority will most likely want an equity position in the deal, and since wouldn't have an active role I'd be getting into a syndication rather than just a JV.

I like new construction since there isn't any deferred maintenance and the properties should be relatively maintenance free for the first couple years (although it's good to include maintenance/repairs in your pro forma and maintain reserves just in case).
