Depending on where you live in the U.S comps are block by block just like they are here where I am.

The house is a 1971 block, slab on grade with truss hip roof with an L shaped footprint. 

there are not enough lawyers on our coast to take care of the massive volume of real estate transactions ala the way its done in attorney closing states.. there would be a big need to scale up if all of a sudden attorneys had to be involved not to mention slow things way down.. the other one that we simply don't do out our way is all the surveying that gets done.. its rare to the extreme to survey a property that was in a lot and block subdivision … but since I build in Charleston you MUST survey there there are encroachments all over the place. but like in Texas they survey lot and block as well.

If you're in say the 3000 block it's probably ehhh or maybe even a little overpriced. 

If there are any obvious issues like posts that are unsupported, joists that look not connected or cut, cracks or crumbling in concrete or block walls, anything that looks wet or signs of pests.I also keep an eye out for what feels like unpermitted additions or covered patios.

An area known as "up and coming" with a handful of craft breweries and  neat restaurants within a block. 

Hey @Pete Mathias, you’re probably looking at a low C Class area but it varies quite a bit block by block so it’s tough to say with 100% certainty. 

Unlike poured foundations or brick/cement-block foundations, the stones aren't very uniform, so there is a little art to replacing individual stones.Sometimes you have to repoint the mortar in between the stones.

I would lean towards nice laminate over butcher block.

I've had substantially renovated properties (kitchens, baths, wiring etc.) appraised over a 1% RV when the one 2-3 blocks over (or on the same block) was under 1% RV.Happy hunting!
