During the Depression and up until after the War they lived 3 families in a single house until they had each saved enough to buy their own house.

Another thing, if your cleaners bring their own vacuums, they could be transferring them from house to house. 

My intention is to house hack and eventually STR the property. 

nothing pointed at you personally but there has been build to rent projects were investors had to put up 50k non refundable and never got their house built.. so I can see putting it in escrow and releasing it upon closing for sure.. thats what i personally do with my new builds although since we average 25 to 75k of upgrades per house buyers have to stroke non refundable checks directly to us for those items.

All these providers have in-house PM and have already done major capex so I think I've minimized my risk as best as I can, but again this is as much about the education as anything else so I'm trying to keep that in mind.Anyway, I look forward to this experiment with excitement and I'm cautiously optimistic it will go well.  

Quote from @John Laseter: Good morning all, Saturday afternoon a gentleman knocked on my door and produced a postcard that I had sent to his house offering to buy it.

There is not a separate entrance to the basement, but the stairs to the basement are in a laundry room in the back part of the house.

Trying to house hack in Los Angeles which is obviously really difficult.

My duplex had an additional unit built in the basement and discovered by city inspectors when a neighboring squabble caused buildings department to check houses on the block and my house had 3 mailboxes out front.

The new owner has not authorized the work on house.
