I'm an agent and a broker myself - and I certainly don't consider myself a free real estate tour guide.

PA Investors:New to the area and plan to take a windshield tour of Pottstown, PA neighborhoods.

If you are sure they are walking anyway, go ahead and just flat ask for their honest opinion of why they don't like it.I always ask them about half way through the tour if it "will work for them", then go from there.Another trick I use is only schedule showings once or twice per week.

I also create 3D tours that make it a bit easier if you can't make the trip & improve exposure on resale. 

I was on a real estate tour of the Northeast in November and there are a lot of great homes looking to be turned around.

@Eric Turner did they give you any ideas on the house you are touring/viewing?

That said, I've toured everyone's house, and I added the most upgrades in my area by a good margin.How much value will an appraiser account for in terms of the 45k in upgrades? 

@Chris Scott  A low-tech way of solving this problem is to "tour" the site by claiming you want to rent a unit.

You can also gain a lot of information attending local property tours and get a feel for rehab numbers.  

I toured a 12 unit property where the numbers looked good, I liked the location and layout, but I found out that the whole thing was constructed with 2x4's.
