I did a back of the envelope analysis for this 3 unit plus general store building and got the following numbers which seem pretty promising.

There are grocery stores in Salisbury, but they close at 7 PM during the week...If you're looking at doing this from another state, it would be interesting to find out how many property managers there are in Salisbury - I suspect not many. 

It has a nice little store, a couple of places to eat and the marina, but not a lot more.

To someone who is completely fresh, changing careers, and just beginning the process of getting their license like you did, but @28 years old, how can I navigate and utilize the BiggerPockets(BP) forum database efficiently and effectively to find the most relevant material that will help educate me in becoming a successful real estate investment agent (wholesaling)? 

One recommendation: if this last home was fresh on the market, they tend to get scooped up quickly; make sure your agent is showing you homes that are stale on the market.

Not unless all you want to do is store wealth (which, by the way, is the majority of the market).

He said he is probably going to file bankruptcy to get a fresh start.Should I reconsider my decision?

Two, if I should just forget about these lots altogether, buy one with cash and wait a year to sell, finance all three then tap the wells and wait a year, or put a shop condo/barndiminium on them, rent out the living spaces while renting out the shops where others would store their boats and RVs?

Buy a can of brake cleaner (any auto store and most stores with an auto department have it).
