Personally, I pay for the best wifi, all the utilities and regular professional cleaning. 

As an aspiring business owner I prefer having an established business entity, separate business checking/finances, business history.When I give my tax info to my accountant at the end of the year everything reconciles to one account or one credit card.Not that you couldn't keep track of all this information via other tools but I prefer it this way.

Remodeled the basement unit and made new/clean looking.

I didn't know if there was something else I should be sending since their US credit is not established yet.

Luckily we used sweat equity to transform this property to a suitable, safe, and clean beach house rental.

Also, since you seem to be very established.

Less expense as well as you're not supplying consumables, paying cleaning, paying for broken furniture glasses, etc. - Rental policy is required.

Because I will be doing the rehab and garage is a clean slate, here are a few options I am considering:Convert it to a master suite, which will make the house a 4/2 with 1500sfConvert it to a studioConvert it to a 1/1 My goal at the moment is to maximize ARV for refi, but I am not sure how the appraiser will look at it.

I need to establish clear rules to avoid conflicts and arguments for my own peace of mind. 

It seems like STVRs could be a solid means of establishing financial freedom within a couple of years, perhaps more quickly than other types of real estate investment (when funds are limited initially).
