How obnoxious will it be to have the dryer vent in the front of the house? Won't it be covered by landscaping? Long runs can be problematic for dryer runs. It can be compensated with booster fans, but that adds another layer of complexity to the system.
I had a dryer vent in the front of my second townhouse. You really couldn't see it from the street or the yard. It was visible when you came up to the front door, but it wasn't the only utility item in that area. At least on this house they managed to put the gas and electric meter on the back of the house. My first townhouse had the electric meter right on the front, it was my piece of Met-Ed artwork on the front of the house. Landscaping eventually camouflaged it. That house had a run that was probably 20+ feet long with at least one 90 degree bend in the ceiling. It worked ok while I was there, I have no idea if it caused a problem for any of the subsequent owners. I only owned it with that configuration for a couple of years. I did run it in rigid pipe without any screws holding the sections together, just aluminum duct tape. Screws will catch lint that makes it through the dryer filter and eventually clog the dryer vent pipe.
