My tenants rented the house sight unseen and complained of an unidentified perfumy smell that they said was making them have headaches. 

Once it arrives, it is stored on a disk and this is what the hackers know and go after.I disdain all such Cloud / Web based products to protect myself and the personal IDs of my tenants.

Watch out for possible hacker attempts

I am also working with a house hacker in Lakewood on a duplex. 

I have self managed as a house hacker of a duplex and later as a more traditional landlord when I moved out of the property into another house.

I work most with investors and house hackers so I can help connect you with some people that can be on your team.

I work with a lot of house hackers and they are trying to conserve capital for as many deals as possible.

@Shane Bishop often house hackers or first time buyers looking to build a real estate portfolio use FHA on their first purchase because of the option to put 3.5% on a multi family, as opposed to conventional where you would be required to put 15% down and even 25% down on a 3-4 family.

Im a fellow house hacker and real estate agent on the Househack Seattle team.

Of course there is a yin to every yang i.e. hackers....Kudos,Mary
