@Jay Hinrichs however I was referring to after you've zeroed in on a target as part of the DD process, the problem I see is if you've missed something for your spotter to ask/do, reliablity /knowledge / trust worthiness of job, etc I'm not sure if would be worth the extra fee(s) ( multiple visits, etc) to not have your own   eyes on ... execpt in thoses rare instances where it would be near impossible, time and/or cost prohibitive to do a sight visit  ( re:  out- of-state or sight unseen) I guess for me  It would have to be one of those "too good to be true" type of deals we've talked about: 1: 1 million lol

The FAA guidance requires a private pilot's license, a class two medical certificate, a spotter, flying no closer than 500' from a building or people, getting prior approval of all flights from 3 to 1 days prior to flight, etc.  

I would network on local meetups and events to see who has the best wholesale lists in the area and see if you can be a spotter for them.

The sales group has "spotters".

roof spotters is who I use if I need a "legit"  roof.. there's bunch of fly by night people out here.. but you get what you pay for.. 

I would monitor the MPLS shot spotter map to find places to avoid: http://www.ci.minneapolis.mn.us/police/statistics/...The fact that they have to update that map weekly tells you something about those areas....There are many people who invest in multi-family in MPLS to help you. 

I can give you the name of some good spotters. if you end up having to seal the subfloor use the attached photo.

Also as a landlord you should know that there are spotters out there.

That's a blip on the radar screen compared with the almost 3,000 REO properties in Illinois last month, according to data from RealtyTrac.Still, even baby steps in the right direction can be considered positive, particularly since foreclosure trend spotters say more consumers are likely to lose their homes given the nation's 9.4 percent unemployment rate.Bank of America, the owner of Countrywide Financial, services one in five residential mortgages nationally.The bank's intention with the program is to remove talk about price from initial conversations between it and cities.

I know that sounds counter-intuitive but "hot spotters" are looking for "escapations."
