Google earth and google street view is great but it doesn't show you real time dataIf I have someone offering on my listing and they are un represented and they do not want to be represented by the listing agent or a buyers agent I know for a fact that my client will get the better end of the deal in this real estate transaction. 

As I'm sure you are aware, real estate is a hyper local game in which markets vary by the street.

You want an agent to go in this order:1. all sales similar beds, baths in 1/2 mile in the last 3 months2. if not enough, all all sales similar beds, baths in 1 mile in the last 6 monthsYou should get a few that match and few that are comparable if not exact.

My mom is the owner of a small (3 beds, 1 bath) home on two acres in a very coveted area between Great Barrington and Sheffield, MA.

Anyone I know who invested in Spain in the last ten years took a bath and I know a lot of people who did.

New carpets, paint, interior French drain with warranty, new structural support beam in basement, 2 new full baths, and much more.

Semi-gloss always in kitchens and baths.  

I’m under contract for a property that is showing 2 bed /1  bath with the county but there is a 3rd bedroom and it appears to be original to the house.

so what would a 900 sq ft 3 bd 1 bath home built in the early 50s in Texas ( Dallas/Houston) have sold for in the late 80s .. and what would it sell for today ?

So, you want 5 strangers living within feet of each other using the same kitchen, and baths, what could possibly go wrong LOL.
