What your money buys in 40031
- Under $300,000: the entry point: smaller homes, homes that need updating, and the occasional estate sale. Expect competition from investors and first-time buyers.
- $300,000 to $525,000: the heart of the market here, right around the $395,000 typical sold price. Move-in-ready homes in this band are what most buyers in 40031 are shopping for.
- Over $525,000: the larger, updated or newer homes, bigger lots, and the top streets in the ZIP. These sit on the market a little longer and leave more room to negotiate.
Run a payment on any of these with the Kentucky mortgage payment calculator, and if you are a first-time buyer check the down payment assistance screener before you decide what you can afford.
Getting around
Main Street La Grange and its shops and restaurants, I-71 at KY-53 (about 30 to 35 minutes to downtown Louisville), KY-146 to Crestwood and Pewee Valley, and the Oldham County Fairgrounds.
Property taxes, schools and the practical details
Oldham County rates plus the City of La Grange tax inside city limits; served by Oldham County Schools. Acreage buyers should ask about agricultural exemptions and well-and-septic inspections.
