good morning, I would like to buy a good volume on the esteem, the only subject among those that forced me to study for the exam that really excites me; in particular, I am fascinated by the so-called "sight estimate", whatever is meant by this seductive expression ... I look for a book focusing especially on estimates of civil dwellings, apartments, villas, farmhouses, etc., which hints only in the alternative to the sector land and sheds ... a simple, clear guide, which privileges the operational, practical, concrete, then I pray who had suggestions to propose to stick to my need, then I will decide anyway, but any advice will be very welcome , thank you, have a good day everyone
