To comply with GDPR we will not store any personally identifiable information from you. Therefore we will serve sub-optimal experience where some features such as Login/Signup are disabled. However, you will be able to search and see all the properties, see agent contact details and contact them offline on your own.
Depending on sufficient cash/cpf monies you have to buy, it will be possible, but it would be safer to do a proper finance for both selling & buying of your property before you make any decisions, which I will always advise my clients.
Do give me a call if you need my service to draft out & advise you on the proper calculations & timeline to assists you in making decisions.
