I think at this point you don't know if she'll really like it, so I'd start small.

If she LOVES Dollhouses then you can get a much bigger "real" one when she's older. (My sister and I LOVED our big dollhouse from 6-12 years of age)

Here are 2 with different price points:

I got this one for DD's birthday next week, so can't say it's the best as it hasn't been used yet. I also wanted something smaller that could be stored on a table but also played with on the floor.

Playmobil has a takalong one that could work for you. My kid will be 3 in a month and loves playing with playmobil and can do almost all of the little piece manipulation herself--though she's very fine motor skill oriented. If your kid is pretty good with manipulating small things then I'd suggest a playmobil one because she'll continue to grow into it and there are all kind of add ons down the line to expand the play possibilities.

We have the fisher price little people one, and I really like it because of the small footprint and it can be folded and put away when you need to. There are better ones out there, but I value space more than a few functionalities in toys like these. The kid loves hers even after having hers for about 2-3 years now.

Fisher price loving family is great. Or even if you get a smaller dollhouse get the FP furniture and family. They are the most realistic and playable.

DD is 3. We live in a smallish apartment so can't do one of the huge ones. When I was younger I had a fisher price dollhouse that I loved so I'm sort of looking for something like that. Have thought about a playmobil dollhouse but not sure if that would be good for a 3 year old. Thoughts?
