The house needs to be sellable, livable, and clean. It does not need the latest trends and trinkets (granite and travertine, AI enabled tech etc).
Just needs to be presentable. The market will dictate your selling price. It's either trending up, or down and you can expect something similar to the comps in the area because others will expect to pay near the prices the comps went for.
I was "lucky" I bought my first home (with a bank loan) on that obama First time tax credit. So I instantly saved $8,000. Then, I snagged an excellent interest rate. Stayed there 2 years, spend about 10k in improvements and sweat equity and sold it for $50k more than we paid due to a job change. Had the job change not forced us to move maybe we still live there today...who knows.
When I came back from that job change...for ANOTHER job change 1 year later, I tried to replicate the same thing with a more expensive home. Bought the home...lived in it 2 years, then listed it...
Barely any showings in a HOT seller's market. All the mid-level homes were selling in 1 to 2 days, ours sat for 3 months and we took it off the market before Turkey Day. Still here today. We will own this sucker outright before we move the next time. We might even be cash buyers for our next home, who knows.
The first rule of Real Estate, Location. The Second rule of Real Estate, Location... and the third rule of Real Estate is... you guessed it, LOCATION! Schools, and wal-marts.
