Its really easy.
Step 1: Go to - C:\Program Files\EA Sports\FIFA MANAGER 10\private_items\house.txt <-- Create a backup of this file.
Step 2: Edit the 'house.txt' file like this:
Original line below:
Palace,Palais,Schloss,Palacio,Palazzo,Pałac,12000000,palace.bmp,2005
Edited line:
Palace,Palais,Schloss,Palacio,Palazzo,Pałac,-712000000,palace.bmp,2005
Save the file.
Step 3: In the game, go to "Career" then "Private Life", then "House". Buy the house that was modified (for example, the Palace) and you will gain that amount of money instead of losing it (in this case you will gain 712,000,000 $).
Then go to "Career" and donate money to club. If you 'bought' the Palace 3 times you'll have just over 2.1 Billion $ to donate.
Step 4: Remember that selling the house will put your bank balance in the Red, -712,000,000 so before doing that simply save your game, exit the game, replace the edited "house.txt" file with the backup you made of the original.
Now you can sell the 'palace' for the original 12,000,000 that it cost and your club will have over 2bn $.
