<prompt> Human: My question is in the title. The new development is connected to our subdivision, although there is a tree line separating our subdivision and theirs. Those new homes are obviously freaking gorgeous and the neighborhood will be safer than ever, Im assuming. How will it affect our home value?  <response>: Not immediately, but yes.Essentially, someday your lot might be worth more empty than with a house on it. Or, it would be worth it to add an entire floor and sell it for way more than the original price plus what it cost to add the whole level.Alternatively, you could end up with a bunch of neighbors who are stuck with 400k homes that they paid too much for.
