This is relevant, I've done both, bought as a single mum and bought whist married, it's a huge difference to have someone else involved in the decision making and to share the mental load and the worry with.
I hope this post doesn't derail the thread, but
I've done both too @Creamteasandbumblebees
I found it made no difference at all, in fact a purchase as a single mum was easier than being married. I guess it's because my XH left it all to me, so I just got on with it and did all the work to buy every house we owned singlehandedly. 5 times I did it alone, despite being married.
Every decision that should have been made as a couple was a drag, as I had to explain to him what I understood from the document, gave him all the options I thought were options, told him what the solicitor said about the document, try and discuss it, only for him to turn around and say "I don't know. I trust your judgement" He wouldn't even read the documents. But I felt I had to do it every time, as it was our purchase, not my purchase.
He didn't even have finance to contribute to the first or second house, and was counted as a dependent on my salary.
Buying my own house post divorce as a single mum was such a breeze. Easiest house purchase I ever made.
Posting this has resulted in the second time today that I thanked God I'm now divorced. I've seen yet another benefit I hadn't seen before. 3 years on and I'm still spotting new ones!
