Well, there are banks that generally exclude financing with people who do not have permanent employment or do not consider such income at all.
With that income, the financing should be manageable with a salary, even if the financing is contractually agreed upon for two people, since joint and several liability is normal.
A power of attorney for receipt will then definitely be required at a notary or lawyer so that court documents can be delivered in any case, as emigration could otherwise lead to enforcement difficulties.
The interest costs and, prior to that, the risk assessment will be attributed solely to the property and the question of how valuable the property is.
I would become skeptical as a financing partner at the purchase price and therefore demand property details for evaluation, which unfortunately are not provided.
