I'm currently investing at the University of Delaware!

Real newbie to the topic so I'm looking for some answers to a few basic questions.Assuming I focus my time/effort (30-40 hours/week/diligent) in this area (tax sale investing) will those with experience please answer ...

And the coup de gras, the tenant in the house we just bought, the one we ended up paying cash for, gives notice and moves out December 31, 2015.  

I own a townhome that literally everyone in that cul de sac is either related or friends except for a couple units.  

We split the parcel and can get 6 lots out of the remaining 1.6acres. we would need to run a new road and culture de sac to get the necessary frontage.

He rose through the ranks and ended up being the President of this company and took it to unimaginable levels and one of the best visionaries in the Country.His MO was to purchase big multi thousand acre ranches and design Master Planned communities i.e Rancho California (now the City of Temecula), my home town of La Mirada, The Hollister Ranch a coastal development north of Santa Barbara and Coto de Caza an upscale private community hidden in the hills of Orange County just to name a few.Point of all this braggadocio is that had it not been for the fact that he was also a civil engineer he would have never developed the creative flair that made he and his company such a huge success. 

@Juan BravoCheck out the people @Dennis Rodriguez mentions.If a bank won't be involved, make sure you do a title search ("Estudio de Titulo"), make sure property taxes are paid and I would get Title Insurance (just to be safe and it's cheap).I don't know about any specific problems/issues/concerns with the owner financing part.
