Lot Listing in Houston Mid/Downtown area

I got this listing recently on a 13,500 sp. ft.  lot in the Houston Midtown area with downtown skyline views and no front or back neighbors.  It had been on the market for $1 mill. last year but was terminated with the previous agent because it didn't sell. Since then the owner has re-listed recently it for $697,000.  I have done quite a bit of marketing for the property but feel like I am at a point of exhausting my resources.  The area is really big on Townhomes and this lot could fit about 3 comfortably so I have reached out to all of the investors that build the townhomes that I can find.  Please help on any suggestions as to where else I can blast the property information.

Thanks in advance
