Apartments are obviously a different scale to what we are talking about (a simple house),
The only rerason I mentioned "a house" was the fact it was obvious you have never built commercially. I am not making bold claims, the type of construction and the price of the land have a huge influence on the cost per m2 as does the access and location.You see a finished building and you try to equate the price by judging it against others. The developer may have a lot more costs than he expects, even before he starts on site.
I wrote this 18 months ago and it still applies:
So when you read what Mark Biernat (Polsky, etc, etc, etc or whatever name he decides to use on the day) posts on these property threads, you know he is talking out of his ass.
"That's again big time BS. We examplined all costs into building,
and total cost NEVER surpassed 1000 PLN/sq.m. built".
I would want that just for the paperwork.
Its the "hidden" extras that you cannot allow for, even with a contingency sum.
So you worked in IT, that explains a lot.
