selling a home without a garage

[James Palin]

I just looked at a property in Ducanville, TX. (suburb of Dallas)  The home had a 2 car detached garage in the back which burned to the ground and was never replaced.  The home does have a pass through carport to which leads to the backyard where there is now a slab of concrete where the garage once existed.  The seller is another investor who has no plans rebuilding a new one.  All the other homes in the neighborhood have a 1 to 2 car garages.  My question is would not having a garage be a big deal killer when trying to sell it after I do the repairs?  Also if anybody has a rough figure to rebuild a new 2 car detached garage, that would be great too.
