One of the secrets about foreclosures is that being first rarely gets you the deal, instead building trust over time, and being there when they finally give up is what works (for example touching base after the judge give the bank a motion for relief from stay on their bankruptcy that has been postponing the foreclosure sale for 6 months - at which point no one else is even still tracking).Finally, the companies that do offer these usually don't bother with filters because there just aren't enough leads to make filtering useful in most geographies, and getting that data costs more money.

I noticed the crime in that particular area is related to auto vandalism/theft, therefore I'm thinking perhaps running electricity to the detached garage to have an electric garage door and motion detector flood lights might add to the appeal as a renter for safety (I'm a woman and during college we had peeping toms and weirdo loitering around garages/parking.)

I say if you are going to bail anyone out, (For the record, I say let it all fall.) might as well put the money in motion on the street.

Around here you can file a Motion to Substitute Purchaser in the foreclosure case and, if the court grants the motion, you can wholesale the deal.

I've researched the no tenant raw land ideas and will continue to while I'm still in uniform.

If you want security cameras and motion lighting just by a little shed with solar panel on top so you don't have to tap into the utilities. 

File an eviction for non-payment of rent and go through the motions. 

Install exterior and interior wireless video cameras that are motion sensitive. 

You need to find a local expert and a local real estate attorney and CPA to help you set your plan in motion.

The appraisal districts are trying to set the valuation close to a true market value but they are also trying to achieve some uniformity.
