$150K is probably on the lower end of the price scale for this type of house. There are similar ones priced higher, maybe a few a bit lower. $150K is also probably the upper 25% of houses in this town, 75% are priced less.
As for the upgrades, yes, it was everything from all new plumbing, a new bathroom, all new paint on every surface, tile over cat-pee carpet, refinished hardwoods, new appliances and sink, new bathtubs with tile surrounds, new toilets, basement support beams, building a huge fence, replaced leaking double pane windows, new A/C unit, new fancy thermostat, added ceiling fans, on and on and on....
