About This Home

345 Ontario Street

Some homes check boxes. This one opens doors. Welcome to 345 Ontario Street, a warm, well-loved home in Ronkonkoma ready for its next chapter. 3 bedrooms, 1.5 baths, layout that actually works. The kitchen was recently renovated, not a flip job, actually done right. Modern finishes, thoughtful design, flows into the main living areas naturally. First-floor bedroom is a standout.
