I purchased my first home back in 2016.
1. Don't get emotional over the home, this could lead to irrational financial mistakes.
2. If you are looking at buying a fixer-upper, be sure to accurately evaluate the cost to fix it up. The house I purchased was livable, just outdated. My agent said that the list price for the house was within limits to similar houses in the area would sell for. I think the agent just wanted to get the sale; as a result, I probably overpaid for the house by 10-15k. This is because my agent was rushing to close the sale.
3. Make sure there aren't any issues behind the walls, such as electrical, plumbing, foundation, etc. My house electrical was not grounded, so my dad and I rewired the entire house. The mistake I made here was not asking for an allowance, or decrease in price because the seller said they would not fix it themselves. Again, this was partly because my agent was rushing things in order to get the sale, something I realize now.
4. Make sure it is not on a busy street, this will help in resale.
5. Overall, just make sure it is something that you want.
