The seller must think he is sitting on a really hot property, or the buyer is asking for too long of a DD period.

.: Someone asked me about a Due on Sale suit I was involved in and it reminded me of the many encounters I've had with trying to buy pre-foreclosures and do SubTo.Some of these brutes are big, ugly, scary, mean and volatile.

I am currently trying to break my analysis paralysis. 

but maybe i don't understand what you're trying to accomplish.  

I will try to do the same in my response. 

Is it advisable to try for sale by owner on Zillow or does anyone have any other recommendations to market this property?

we're trying to protect you and your family - hence the 'suspicion' =)

First, and i don't know why nobody else is catching this, you MUST go directly to your broker, sit down and discuss all this with them. 

I am trying to learn all the things before I decide to either build on these lots or just hold it for a while. 

(You’ll pay higher interest because it’s a rental property, and, if you try to do it in a corporation/LLC you’ll pay an even higher interest rate.)
