Hi,
Basically: The financial value of something is what you can get for it if you want/need to sell it. Not in 5 years, but now. You can put whatever price you want on the price tag, but if you can't sell it for that, it doesn't count. In other words, the negotiated price belongs in the category 'desired value.'
Now, unfortunately, the purchase price is also not the financial value – because if you have to sell immediately, you usually don't get that value either. Either you paid too much when buying (poor negotiation?), or overlooked serious defects that further decrease the value, or something similar. Plus the problem: those who have to sell usually get less than those who could postpone the sale by a few more years. If the financing fails, however, you are forced to find a financial solution, and what you then get or can get is what the bank can actually accept as the value.
Regards
I.
