Mike, let me break it down for you. Mission Estates is located right outside a McDonalds, Park N Ride, a gas station, and a noisy 680 freeway. The original poster was kind enough to point these things out. And of all those negatives, I don't understand why you're so tunnel-vision focused on the road ENTRANCE to the community. Like I said, even if you built a beautiful, elaborate, entrance, Mission Estates would STILL be located right outside a McDonalds, Park N Ride, a gas station, and a noisy 680 freeway.
That being said, the appeal of the MSJ schools and well appointed interiors has allowed Robson to sell these homes for 1.5-2M or so successfully. The houses are already priced according to demand and the speed at which Robson needs to sell them. So why on earth would Robson feel compelled to spend even MORE money (read: cut profit) to build a new entrance that wouldn't sell homes any faster?
Buyers have tons of reasons why they like or dislike a home - front door facing wrong direction, don't like round windows, don't like the number "4" in the address, etc. It would be impossible for any seller/builder to cater to 100% of the possible criticisms people have. You and others may not like the lack of a grand community entrance. I can tell you that buyers in Mission Estates are probably not idiots. Therefore, you can't "fool" them into ignoring the McDonalds, Park n Ride, and gas station right outside just by constructing a nice looking archway to drive through on the way in. And perhaps the traffic, noise, odor, and chemical exposure that these things bring don't bother you personally, but they are a concern for most people. Buyers who would NOT buy because of the McDonalds, Park n Ride, gas station, and freeway, are not going to suddenly change their minds if Robson builds a nice gated entrance to the development. And honestly, this poor location in MSJ is the biggest objection people are going to have, and revamping the entrance is not going to change their minds.
Bottom line is this. If you wanted an improvement to the community entrance, you should have negotiated that into your contract. Why would you expect any builder to cough up their already low profits and build something additional for free? For FREE?! Just because you complain? Get real, man.
If you have you heart set on a grand community entrance, perhaps you can take it up with your HOA. I'm sure that if there's enough demand among your neighbors, they would be happy to increase HOA fees to raise money for the improvements to the entrance. However, given that people are up-in-arms about the lack of value of your current $197 HOA, I doubt that's going to happen, my friend.
