Buyer’s remorse

Bought a property in Melbourne which we really loved at an auction. At the end our bid won and we signed the contract. We felt really happy to purchase a property which almost ticked all boxes. However the feeling of happiness lasted a day or two and now we feel stressed out, which seems is a Buyer’s remorse. Lots of doubt are circulating in our minds: what if it was a wrong decision, maybe we overpaid, will price ever increase, should we have bought in another area, etc etc. Are we overthinking? Is it normal to think like that? Want to know other’s experience…
