A house will rent anywhere if it is listed at the right price. I am a property manager and all of our rentals in Mountain House are occupied. I also live here and it is a great community but you will get a better return on your investment buying a rental property in Tracy, less expensive, lower taxes, you may get a little more for rent but it won't offset the cost.
Well, it depends on what you mean by good. If you're just looking for a potential pool of renters, then it's good. If you're looking for high rental returns, then it's fair to decent. Unless you also live in Mountain House, it doesn't make for a great rental situation.
