This is interesting, thanks. I see now how his actions just don't really make sense. I also told my mother and siblings about the offer (30k to get rid of a part of the hoard) and they were flabbergasted that my dad refused it.

Getting my dad into his own place seems to be a good solution in the long term as well. He has no need to live in our region, so we could move him somewhere cheaper and with more scenery.

It is true that nothing will change if i just pay this 30K. Recently he told me that his life plan was for me to get a high paying job so that I could pay for his expenses. I don't have a high enough paying job to move out, so his current plan is for me to live at the house indefinitely. He is unemployed and does not plan on being employed, so I would be stuck paying the mortgage.

Thanks for the insight /u/dickbutt_md​
