Rental properties have a higher standard for dryer venting,, most city inspectors will require you to have smooth sheet metal duct, not any of the accordion type dryer vent hoses made of plastic or flexi metal.. and must be vented outside..I'd call city talk to inspection department and find out the regulations.. as your currently "thinking" about adding a dryer... honestly we had a huge issue with trying to install a washer and dryer in a 4 plex,, the city inspector would not permit use because we didn't have a egress window in the basement for an additional way to exit,, code required 2 exits out of basement to have a washer or dryer for use.. basically the basement was off limits. because of no 2nd point of exit we couldn't even let tenant's down there so we had to lock it off. 

You need to take the time to sit down and study your state landlord tenant regulations.

Does that violate regulations with the state?

They are asked to bring a copy of their government issued photo ID and a recent pay check stub to the showing. 

For this to be implemented it would need to be regulated very strongly which means the US government would need to write up the regulations.

I have many military and government friends who have seen this before, but we all still wonder... what's going to happen if the government stays shut down past the weekend?  

This is illegal and highly regulated.

@Sabrina Rios Almost anything that you want to do with real estate will require money up front, if you go with FHA or FHA 203k your down payment can be 3.5%-5%  the only real way to do no money down is the government programs that allow it, but they strongly favor owner occupied single unit properties. 

Im locates in New Jersey so I’ll have to look up the regulations here.

If they'll do it to the government, they'll do it to you.If this property is buried in their other business, then that may be legit.
