at the grocery stores there should be a rack of free real estate mags. Those are helpful. Also check for established builders websites. They might have a listing of all their homes. Finally most major real estate agencies have websites which have homes they are listing.
if you’re looking for big garages the above suggestions will help you alot if you research yourself.
I forgot about those magazines. I got one and found this really great house listed.
Problem was it was already sold.
Like about ten years ago.
Maybe their information is more up to date nowadays.
