The busy street will always be a drawback in the eyes of some buyers, and that will be true when you go to sell it, if you take that path. What else does the property offer besides the amazing back yard?
Evaluating and comparing properties by listing their strengths on a piece of paper side by side helps bring things in to focus. Or, using a point value system to see how the property overall measures up to your criteria.
It's never stupid to buy a house that you love. Just walk into it eyes wide open. Realize that you will probably get a great price on the house and that you'll need to pass that great price on to the buyer someday. You'll also take longer to sell it. If you can stand the time on the market and you realize that it probably isn't going to sell for quite as much as it would otherwise, you need to negotiate the price aggressively, or make certain that the price already is low enough.
Do remember, circumstances change and you might, at some time, need to sell quickly....
RE/MAX Bryan-College Station
Everyone gave solid advice based on the preconceptions represented by their individual markets. Real estate is intensely local by nature. Your previous question indicates that you are interested in the Lexington area; since Noemia appears to be the only REALTOR familiar with that area--give her answer the greatest weight. If this is a common condition in that area, it may not effect the value or resale potential adversely. If these points truly are a negative, but you really like the house anyway, go for it! Just be sure you get a fair deal, realize your appreciation rate may not quite match the standard for the neighborhood, and know that when you wish to sell, it will probably take a bit longer than the "average" home in your area. All that said, when you resell, there will likely be a buyer who loves the place for the same reasons you do, it just may taker a little longer to find them! Best of luck!
