There was no furniture whatsoever, so I have now constructed and installed the kitchen and apartment furniture.

It's amazing how nice a lot of the hardware that is used in cheap flat-pack particle board furniture often is.

Tell him that he can tell you what paint and supplies he needs and you can order it on line and pay for it and he can pick it up. 

@Luke Myers You may want to talk to some mobile home dealerships or local mobile home supply stores.

Find good quality used furniture. 

It took about a month to accumulate enough furniture and appliances (slept 9). 

We weren't able to negotiate them down any further but we did negotiate for some maintenance to be completed and furniture to be left, since we were furnishing it as a vacation rental anyway.How did you finance this deal?

Once you squeeze your 38 year old (and now slightly heftier bulk, get off my back I like craft beer and wine) through that hole you can then point the aforementioned fireplace at the P trap while you begin to heat tape the frozen toilet water supply line because "bro, toilet won't flush yo....".

I think it's very risky to try and analyze deals (at least the construction portion) based on the few photos supplied with the wholesale packet.

Longer term, I can also imagine integrating some custom workflows for cleaning staff to inventory or reorder supplies behind a purchasing passcode, work through contactless audio versions of cleaning checklists they don't have to look at their phone/list to work through, or just allowing for guests to quickly look up info, recipes, local recommendations, etc when trying to figure out what to cook or where where to eat around dinner time.
