First of all, thank you for all the replies so far. I will certainly be contacting recommended agents for their opinions and advice.
I do not believe our current positions would be sufficient. However, I do have a degree (within the real estate industry) which could lend itself to a few on the list and it would depend on how far back they consider this applicable together with the limited experience I gained. Also, I have not got my chartered qualification and this is one of the things I will need to check with regards to relevance for acceptance. Ultimately, I would like to see how easy/possible it is to become a CPV (Certified Practising Valuer) with the API with my current qualifications. I may have forgotten large portions of my university studies so know I will need to start as a trainee/assistant role here in the UK so I'm relying on a lot of goodwill from future employers and immigration to realise the move.
My wife is currently studying a part time BA degree in Childhood & Youth Studies which is due to finish in 2023 (we are investigating if this can be switched to full time which could allow a potential completion in 2022). She thinks this would lend her a position within the education and/or social worker line of work - she would prefer to do the latter but would like to know if most youth work or social care support workers require a degree in a relevant field to gain employment? She is currently a support worker for the Independent Reviewing Officer at our local council since October 2019.
If we are looking at 3-4 years minimum, then it is likely that we will have an infant with us. Is there anything else we should be made aware about this? Are there any extra visa costs/things to consider?
Unfortunately, New Zealand and Canada just do not appeal to us in the same way. We prefer the Aussie culture plus we have family and friends dotted about that we simply do not have in the other two countries as lovely as they seem.
We are conscious of the costs and have already started saving should we be given the green light! I'm trying to remain optimistic.
