It seems that the ones formed 2012-15 are in a safer place.

Curious to know how it's going and if it's a good alternative to selling my properties or trying to do a 1031 down the road. 

There are alternatives note investors have and thats new origination's where of course you will have some bummers but your not starting out with a defaulted borrower at the get go.

I have seen these appreciate very well given that they are the alternative for those who cannot afford a 3 bedroom home.

Alternatively, does anyone know of a loan originator who can help me create my own friendly line of credit from one of my LLCs and record the liens?

Alternatively, you can hire a title company to assist you.

Comparing two deals - with almost same price point #1. no rent increases but Percentage rent lease - There is a base rent ( ~65% of NOI)  and the rest is percentage of their gross sales in last 12 months#2. 10% rent increase every 5 yearsAs a newbie option #2 seems preferable /safer to me, and #1 may be slightly riskier.

Not as good of a deal as a new card but if you're having trouble with a new card, could be a good alternative!

Alternatives? 

However, in inflationary environments, real estate can be a safer investment than other asset types because home prices often stabilize or increase over time as more buyers look to real estate as a hedge.
