Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).

Tyler, I am so sorry you had to come on here and put this much effort into a defense.

I want to reach out and get feedback on where I would be able to find off market self storage facilities and how to approach the owner?

In general I have unfortunately never gotten much return on any social media marketing. 

Hi Esther,You’ve already put in great effort, and your services are definitely valuable!

Their children (now in their late 40s) inherited the house, but they have not listed it on the market, and I heard that neither is willing to move into it from their current setup, so the property has been sitting vacant.

The pro development and affordable housing advocates use the term NIMBY, but I suspect it is the rare person that buys in a single family zoned area that would be thrilled to have 17 units (qp16 additional units added) in the lot next to them.My initial protege was the land source on this effort.  

Not an easy thing, but saving 20% or more on the cost of a new home seems well worth the time and effort if you ask me.

Start by exploring books, YouTube channels, market research, and analyzing trends in neighborhoods.

Now that the property has been renovated, I have recently been applying my efforts toward starting a syndication to scale up to the purchase of larger properties.
