Background:
I'm a single mum. I earn a decent income, and could earn much more if I didn't handle pretty much all of the child caring responsibilities for my daughter. She is about to start school and I expect at least another year of covid school closures etc.
My ex pays the CMS maintenance every month, but sometimes threatens to withhold funds. He was also fired less than a year ago. He bounced back pretty quickly.
That's all to say that there is a chance I could earn a lot more in a few years' time, but it's not guaranteed. I also probably can count on the CMS funds, but I'm fearful of doing so.
The housing options within walking distance of school are a small flat that is easily affordable, or much more expensive houses that would be harder to maintain and require updating. The flip side is that theoretically I could add value to a house, and I'm probably overpaying for the flat due to the insane property market (I have an accepted offer).
The traditional advice is to buy the most expensive home you can afford. AIBU to buy the smaller flat, when I could afford more? It has outdoor space where my daughter could play (but no private garden, just a patio) but is pretty small.
