What a client had to say about their experience... 

Joanne’s the one you will want!!!

Joanne was so connected with me the seller I could not have ask for anything more. She walks with you hand in hand from the first page of the for sale document to the very last page of closing. She was always there or reachable if I had any questions,
concerns, illness, frighten, doubts or whatever may come up during this process. 


This is a heart wrenching process when you don’t know what you are really doing. I have to say Joanne knew the process, not a question that came up that she didn’t have the right answer for.  When the right buyer came along she walked them through the process of getting qualified for the park, so there would be no surprises at the end. She is very knowledgeable about New England Village.  I chose her over others because I knew she had the experience.  I had seen her signs with the American flag on them in that park almost every day for the 7 years I lived there, they came and went usually faster than normal. 


She will work with you whether you want to be out in a month or a year. She is very very honest and tells everything up front, so my suggestion to anyone who wants to sell or buy, talk to Joanne, she will get you the best price either way.  I feel I have made a friend for life, she extends above and beyond her job to help anyone, anyway she can.  I would surely use her again if I moved back to the bay area. 


Thanks to you Joanne I am on my way to the new chapter in my life.

Love you,

Elaine Alcot

Benefits of owning an Encore Home by ARM Homes...

Upscale Amenities and Details—Attention to details are the watchwords of the craftsmen who work on Encore Homes by ARM Homes. From the hand-applied old world finish on the sheet rock walls, vaulted ceiling, floor-to-ceiling windows and crown mold-ing to appliances and fixtures oriented to seniors such as comfort height toilets and low entry showers and tubs, lever light switches, and so much more. Every design decision in an Encore Home is made with the homeowner in mind.

Gourmet Island Kitchen—The island kitch-en features wood cabinets with soft-closing drawers, man-ufactured stone counters and full backsplashes, upscale Kenmore Elite stainless steel appliances, long-life LED recessed lighting, a dining area with rubbed bronze chan-delier adjoins the family room/kitchen—this open concept is ideal for today’s lifestyle.

Family Room— or Great Room-- The spacious family room or great room opens to the kitchen and features a sliding glass door out to a long covered deck with custom redwood railings. Com-pare this feature to brand new homes, where to save money, factories build new manufactured homes with no family room and only a small front porch. This forces homeowners indoors, spending their leisure and enter-taining time in one room, the Living Room. You can still order a custom home with a family room, but prices in-crease dramatically. This Encore home features a living room, a family room, and an outdoor deck!


Generous Covered Deck— features hand-crafted redwood railings along the expansive covered deck with a sliding glass door to the family room. This is ideal for entertaining. A utility patio on the carport side of the home is ideal for barbecuing. A large new TuffShed storage shed features a raised floor, a window and a large locking door. Compare these features that enhance your daily living to the brand new homes that usually only offer one postage stamp size porch that is not conducive to visiting or dining outside.
