Quick backstory: Separated 2 years, 2 DC (6&4), completely amicable, done mediation and agreed on everything. No issues here. He's living back at home as housing crisis (we're not in UK), price for rent astronomical etc. Agreed to sell family home and both buy again.
Getting to the main point. We are at the stage where the sale will go through shortly for the family home. I cannot find a house to buy, he cannot find a house to buy (housing stock shortage). Have ample equity, mortgage approval etc. I have no choice if the sale goes through but to rent, he'll still be stuck at home with parents and not able to take kids overnight (his mum has people renting rooms as her retirement income, this will not change). He can't rent and pay me maintenance (rent is twice a mortgage payment). He is over here every day seeing the kids, and has to look after them here on his days when I work etc. Equity money will just be sitting in low interest account FYI when selling.
Suggestion is that we stop the sale, he moves into this house and takes over mortgage, bills etc (house still in both names and mortgage continues to be paid off and any equity 50/50 down the line). I rent and we then go to giving kids a proper routine as according to mediation agreement with overnights with both. At present neither of us has any remote privacy or free time because everything centres around this house. If I even need a break I have to go away somewhere, as does he because of living with his parents. Financially will suit us both and it's fair on both of us (FYI I do not like living in the house because our marriage ended straight after buying it, I'm desperate for a fresh start as such).
Housing market is so volatile, we believe this is best going forward the next year or two. We have the safety net of still owning the house god forbid something happened to one of us. We get along perfectly (marriage a death by a thousand cuts, nothing major). We co-parent brilliantly, spend all big says together, Christmas together etc. But this affords both of us time and space as well as a solid routine for the kids.
AIBU to halt the sale and see how it goes? We agreed we'd get a legal written agreement with our solicitor to this effect just to protect us both. Or should I bank the cash, move and rent and have the same situation as I'm in now?
