I actually have 2 of my properties on the market.

i personally use my regular phone but you could use a google voice number or an actual physical work phone with a different line. i'd do google voice so you're not carrying around 2 phones. :)

Are you an actual buyer or a wholesaler? 

Ask for references from a few realtors.I will say that the front office/paralegals are the people you actually want to get.

After reading some of the other replies, it seems that this actually could be a "good problem", as it is an opportunity to add some value to the property!

I will be adding a utility closet in the 2nd floor full bath to store linens etc.For added value, I would actually add the washer/dryer.

Is it possible to actually have your roommate paying most of your mortgage in an expensive city like NYC, via house hacking?

I guess when you think about it that way, they can't really damage things when all their time is spent sleeping or sitting on the couch watching netflix.
