I think as long as your home is warm and welcoming it shouldn't make any difference, and she's not actually been or said anything, so don't let your insecurities get the better of you.
I do get the issue with comments though. My father lives in social housing and hasn't got two pennies to rub together. We moved to our first property down south, about 17 years ago, it cost us about 250 then, and we'd stretched ourselves and he walked in and said "is this it, I was expecting better". And then later during the visit we were talking about patios and his partner said something about "the fake York stone you have now". Most bizzare, it wasn't fake and the pair of them lived in a council flat but were sitting being all judgey looking down their noses at it.
As my daughter was privately educated that home was clearly a lot smaller than some of the mansions the other parents had. It never bothered me but I was aware some of them looked around in surprise and said nothing. It was like your home dictated your financial status. Ours clearly screamed poorer than everyone else.
We now live in a large house with a large garden and due to a year end event we held for our daughter , many of the same parents turned up to get their kids, I got lots of "god what a beautiful house" and a huge amount of quizzical looks as in how did I go from that to this. Oh and wanting to be Mates. My behavuour didn't change, I didn't care then and I still didn't care.
Your home doesn't change who you are. We moved when we had saved enough, wanted to and could afford it, we were happy enough in our previous property and owned it for a long time as it suited us, even though we could have moved earlier. But as I grew up in social housing, I guess I just don't have the snobby gene. I recognise it when I see it, but can't say I've ever let it bother me.
