Buying a home is more that the mere need of a roof over our heads, it is a significant investment and to a great extent it should be looked at as a business. The questions that you pose will be the same ones that future buyers will come up with...it comes down to VALUE!!! Are you getting this property at a value that reflects all these potential issues? Good Luck Investing
People get their panties in a bunch when buying property next to freeways, highways, busy streets, etc., but in reality its not something you should worry about too much. Unless it is some unique scenario where the noise is SEVERELY loud, to the point it is actually noticeable at night, it shouldn't really impact the value of property at all, or the ability for resale. Yes it may affect the property, but so does the square footage, number of bathrooms, and the living space. You stated that the home was in a good neighborhood, so as long as you already know exactly what you're buying, you shouldn't have much of a problem, and you shouldn't consider it a "risky purchase". You'll be able to sell the property at its value at the time of resale, as long as you understand what that value is then, and is now, you WILL be able to sell it no matter if it is located next to a freeway, etc. Good luck.
There will be those that have the same questions as you have now. The value of a home right next to a freeway will be lower than one that is further from the freeway. Is the roof on this home a flat roof?
With homes with the flat composition roofing (sold by the roll) do require routine maintenance to make sure that water can drain properly. You have to make sure the drains are clear of debris
