Form Modelo 714 is Patrimonio only
Form Modelo 214 is Patrimonio and Renta, income and wealth tax on one form.
Be careful is you use the purchase price you will most likely pay too much tax as the cadastral value is lower its based on sie of aprtment or house and the area its in.
You need the IBI for the other calculation and you need NIE stickers to go on the form. You will not get the IBI for a year or more so in my first 2 years I only paid one tax, this seems to be the norm.
I have had my administrator do my tax and they charge about 80€ and get the forms and stickers, this year I will do my own but I will have to go to the local Hacienda to apply fo stickers, I think the nearest is Estepona or Marbella.
