Read The 7 Levels of Communication by Michael Maher and that will give you great strategies at no cost to work your sphere.

Quick notes about me: I was born and raised in NYC (Queens, Long Island) Current 2-family rental is in Queens Village I work full-time at a growth-stage technology company in NYC on their Strategy team My goals are to get 10 additional doors under my management in the next 3 years. 

I am interested in using the BRRRR strategy but have very little knowledge on what repairs/rehabs cost.  

My thought is I can buy the raw land, and sell it back to the owner of the main parcel, who recently purchased it from a bank as an REO.The property has access to a main road without going through the other parcel, but is currently behind a contiguous fence from the other parcel.Does this strategy make sense, or am I putting myself in a poor position by doing this.

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!
