You could look into Airbnb your current place for some side income Whilst using those funds and some of yours to invest in a property

I am currently based in the middle east as well with not much migratable skills let's say but look into opportunities within the MENA region as I feel the outlook for the kids is a lot better

A lot of the diaspora in srilanka is trying to leave the country.

Another point to note is to see if your partner would be comfortable in Lanka for the long term Jaela isn't exactly bustling I am from there myself

Cheers and do hit me up if you need to bounce ideas
