Travelling around the Mid North, I spotted this oldie but a goodie. Typical of many that dot the landscape around here.

Who lived here?
How long ago did they vacate the building?
Why did they leave?
Looks like it was a great location for a renovation into a B&B?
So many questions so few answers, so if anyone can fill us in on some history it would be greatly appreciated.
The cache can be found by counting the number of chimneys seen from the listed co-ords. This is A
GZ is at...
S32 57.(7-A)(8-A)(3-A) E138 30.(4xA+1)(A-A)(3-A)
Checksums: S12 E10
The abandoned house is on private property, but the cache is accessible without going over any fences or a gate, so please do not enter without express permission of the land owner.
Also be careful at GZ, and watch out for traffic!
