You will be considered the resident of US for tax purpose if you meet substantial presence test.  

Still just in exploratory / learning territory on these kinds of multi-units, would appreciate any advice.

Also, seems like there may be something going on that the homeowner is having appointments without the presence of their representation.

@Aarti Bambha I wouldn't attempt to track by "zip code" as it can cover a lot of territory.

I would be living under the same roof, different unit.Property numbers that I've thought about:Listed price: $79,0003 units (currently renting at $425, $450, landlord/$0) - month-to-monthRight across from school, in a Class C neighborhood, street on nicely kept residential with regular police presence, but sketchy loan places within 5 minutes and crime map is full of "disorders".House built mid-1800sMonthly ExpensesTax -- $138.75Insurance -- $62.50Utilities --$60.00 (split with girlfriend)HOA -- $0Vacancy -- $60.00 (5% of the time or unless I really mess up Valentine's Day)Repairs (cleaning) -- $100.00CapEx (replacements) -- $100.00Prop.

I plugged a phone number into a search engine and came up with nothing.BTW I found it odd that this website didn't alert me to the presence of these two responses.

Back then, I had a collection of working microwaves that tenants left behind on moves.I don't rent to section 8 tenants, because generally speaking they're not the type that can draw on an IRA if something comes up, so having this problem comes with the territory IMHO.

Any QI with a national presence can help you out. 

The basic data points as I think of them:---What is your gross rental income per booking---What is your cost per welcome basket---What is the increase in chance of a repeat booking, based on the presence of the welcome basket---Secondarily, what is the change in likelihood of a great review, based on presence of welcome basket     If you have a high gross rental income per booking (say average $5k per booking), and you can offer an incredibly high impact welcome basket at a low cost (say the basket costs $20 but includes dates harvested from the date palm trees located on the property), you will likely find this yields huge returns in repeat bookings and reviews.    

Denver was hit pretty hard due to the presence of telecom - a lot of fiber companies went down the tubes.
