come si calcola il prezzo del terreno..

In questi giorni/mesi ho imparato una nuova cosa:

Come si calcola il prezzo di mercato di un terreno fabbricabile?
Due sono i parametri fondamentali che caratterizzano un terreno:
  1. Superficie: esempio 600 mq.
  2. Indice di fabbricabilita': esempio 2.
Dai due parametri si puo' ricavare la:
  • Cubatura fabbricabile: moltiplicando la superficie (1) per l'indice (2) ottengo 600 x 2 = 1200 mc (metri cubi). Cio' significa che in un terreno di 600 mq posso costruire al massimo 1200 metri cubi di casa.
Qual'e' il prezzo di vendita degli appartamenti nella stessa zona?
  • Prezzo di vendita: di solito espresso al metro quadro. Esempio: 2100 Euro/mq. Un appartamento di 100 mq, cioe' 100 x 0.9 (90%) = 90 mq commerciali costa 2100 x 90 = 189.000 Euro circa.
Qual'e' il costo medio di costruzione?
  • Costo di costruzione: un prezzo economico medio realistico e' ad esempio 1100-1200 Euro/mq.
Calcoliamo quanto puo' rendere al costruttore il terreno. Ovviamente piu' l'indice alto e piu' il terreno rende perche' si puo' costruire di piu', quindi:
  • 600 mq x 2 = 1200 mc
    1200 mc : 3 m = 400 mq, 3 e' l'altezza di un piano, cosi' ricavo la superficie
    400 mq
Calcoliamo il ricavo:
  • 400 mq * 0,9 * 2100 Euro/mq = 756.000 Euro
Calcoliamo il costo di costruzione:
  • 400 mq * 1150 Euro/mq = 460.000 Euro
Calcoliamo il guadagno lordo:
  • 756.000 - 460.000 = 296.000 Euro
Calcoliamo il guadagno netto:
  • togliamo un 10% di tasse, un 5% di oneri di urbanizzazione = 10 + 5 = 15%. Questo e' un valore medio.
    Quindi: 296.000 * 0.85 = 251.600 Euro.
Quindi per andare in pari il terreno il costruttore deve pagarlo 251.600 Euro, per guadagnarci almeno un 20%:
  • 251.600 * 0.80 = 201.280 Euro
    che al metro quadro significa: 201.280 / 600 = 335 Euro/mq
Quindi il prezzo di mercato per un terreno di tale metratura in quella zona e' di 335 Euro/mq.
Ho creato un foglio di calcolo apposito per fare questo conto.

Interessante ma non sono daccordo sul 15% di tasse ... mi sembra troppo poco! Difatti il mercato tende ad acquistare terreni ancora agricoli e sperare (e spingere!) perchè nel prossimo PRG diventi fabbricabile :)

Hi, I discovered your page on and although the information
seems great, I suspect your blog may possibly be having a couple web browser compatibility snags.
If I use Firefox, it loads okay, but if I use Chrome, it pulls up seeming overlapped and off-kilter.
I simply wanted to provide you with a brief heads up,
that's all.

My pitcher's most effective boast is without a doubt the item's merging hot coffee
/ espresso, profits, teas alongside rich and creamy frigid beers for example, the drinks.
Highly pricey. Getting this done meshes with all of the
other chrome steel equipments i always feature inside of my home and
appears sort of a reputable art work. And more, Breville is known as a top juice machine, and of course the best to fix.
