Property Description
This home has just about everything on a person's wish list! Highly customized and expanded Deer Ridge home on a fantastic lot. This home is loaded with quality upgrades and charm and the heart strings start pulling from the moment you pull up to the curb. Only 450 square feet was added to this plan 3 model but added in a way only a prominent architect/former owner can imagine. Quality appliances, close attention to details, terrific views, an inviting pool and spa, a wraparound covered patio with serene views everywhere, a large grassy area, plus a lower level yard with 19 fruit trees await you. There are 4 bedrooms, 3.5 baths and an added bonus room and wonderful sun room. The home has been well cared for with fresh paint on all the wood exterior, new pebble tech added to pool, new carpet, newer HVAC system, new roof underlay and a huge finished attic. There is a 3 car garage and parking for a boat, trailer or small R.V. Homes like this don't come up often!

No recorded sales in this range. Select All available for older records; missing records do not mean the home never sold.
ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
