I love the entire concept of fix and flips.

It is a story in today's 8/8/14 Wall Street Journal but is subscriber-only yet somehow, through Google, one can access it.I am formerly of TransUnion so if I can answer any questions about scoring, credit bureaus, or consumer credit, please ask. 

If you are going to do it, seriously consider what the important parts of the business are, and don't get bogged down in the concept that being busy is being productive.

I had one of those in an apartment that I rented like 25 years ago, so not at all a new concept; IIRC there was no upper rack so loads had to be smaller.

I will work toward bringing in lot renters and I like the concept of owner financing the trailers, but in the mean time I need to maximize growth to reach my goals.

Without knowing what type "lien" you are referring to (or a hint by what person or company is pitching such a concept to you) it's pretty impossible for us to guess how to direct you.

Until you explore that concept, I would put the Sub2 plan on the shelf.  

He understands the concept of leverage, so I assume financing.

Rents can be very high in the more desireable sections (ie Journal Square), however that is not the case in the less trendy (and rougher) sections. 

I like the concept of a full time supervisor to hire qualified subs.
