It all depends on your strategy and current needs.  

For example I would consider anything with less than 20' clear height functionally obsolete as industrial buildings are growing in height every year to accommodate new high bay distribution strategies. 24'+ is ideal.

I need to come up with a good strategy for tying up this property while managing holding costs & risk (both the risk that market shifts drastically and the risk that I lose the seller)CONTEXT: I'm an investor in Bergen County, NJ - my direct mail turned up an owner who plans to move out of state at the end of the school year (she's a teacher retiring).

My exist strategies are 1.

Some of the "no money" conversations and strategies also depend how liberal you are (shades of @Jd Martin here) with defining your "own money".  

As far as financing goes, I need to look into low and no-money down options, and was hoping to get leads on reputable, trustworthy HML's in the Boston, MA area and any other suggestions on creative financing strategies for fix and flips! 

We are currently developing a bid strategy to maximize the potential sale price of the underlying property."

I want to start using the BRRRR strategy on vacation rentals through airbnb or VRBO, but will I have issues when I go to refinance?

I have just completed my first Fix & Hold single family rental (BRRR strategy) and closed on my second property, which I will renovate this fall and sell. 

While the returns can be much greater, the cheese moves much faster in the game of short-term rentals, and the knowledge and strategy required when it comes to existing and future government regulation (on the city, county, and even state levels) is hugely important as one could get put out of business at any time.
