Home is the place where it feels right to walk around without shoes
Home is where you can scratch where it itches
This is a question only you can answer, but to give you an idea what other first time home buyers are thinking about when choosing their first perfect home. The first thing you need to know is that there isn't a perfect home at all. You can get close to a perfect home by first determining affordability, than you need to evaluate key fectors for example and not in any particular order: 1- number of bedrooms, 2- location. 3- Schools. 4- Transportation. 5- Commute time. 6- Shopping etc... When you combine all of these factors together, it will be your close to perfect first home.
This is like picking the perfect partner. There is someone out there for everyone, and someplace for everyone. No place is perfect, but you want to figure out which home is the closest to perfection for you.
I did a blog post about home buying that goes into this in great detail. I've set up a link to it below. It was part of a long series of steps to home buying. I hope this helps.
