If a municipality says: Development will be in June next year, then plan more around November,... therefore I would not recommend signing tenders and loan agreements yet. The municipality is as fast as it is, and you can't really put pressure on them. However, your construction may be delayed because of this - you will lose money due to commitment interest - your craftsmen's offers may no longer be valid - you will have to tender again, etc. Patience is unfortunately a virtue needed when building a house. Clarify your financial situation, see what your budget is, how much house you can afford, and start planning - if you want to pay for the planning already from the loan, you probably have too little equity,... Ancillary purchase costs must also be paid from equity!
