You don't say what your age is, what your savings and housing prices are. All the info is that you're a single female and you like the area and plan to stick around.
Buying a house is fine in these circumstances, but you're also going to have to consider the costs of home maintenance, taxes and insurance. You'll have to buy appliances, yard equipment and find a good handyman or figure out how to do basic repairs yourself.
If you plan on getting married and having kids, that's also a consideration of how much house you might need... but you have no way of knowing right now if that's a year off, or 5+ years. That is a whole bunch of uncertainty to base a house purchase on, so honestly, if you're really set on buying a house, I'd buy a modest sized one instead of a larger one that you think might be your forever home. You will be paying more taxes for a larger home, and utilities to heat and cool the house, and wasted space that you might use in the future is no reason to go bigger.
In my case, it's a damn good thing we didn't buy more house than we needed in the beginning (we did a "starter house" - a small 1300sf in a decent neighborhood) thinking we were going to have a bunch of kids and get a larger house once we outgrew this one... but no kids, so that didn't happen, and boy would that have been a waste of money if we had started out with a larger house. What we have now is perfect for us and will be until we retire.
But in your circumstances, I'd say keep renting, and look for the "perfect" house that would be comfortable for you and down the line, maybe another person. If you end up having kids, you can always look at a larger home at that point, but no use paying out a large amount of money now on your maybe/someday kids before they're hatched. ;)
