Travel and per diem will be included. 

I highly recommend you travel to the market yourself and spend a couple days driving around, looking at various properties, if you are going to be buying anywhere.  

You can always house hack, buy a multi family, do a trailer park and live in a trailer etc.

I will also be tracking expenses related to repairs, maintenance, travel to and from NV, hotel stays, meals, gas, and other regular business costs.In the long term, I aim to purchase additional properties under the business name, but I understand I need to establish at least two years of income and credit history before doing so.The issue I’m encountering is that my accountant has not provided any guidance on how to structure this scenario.

For instance, there is currently a nursing shortage across the US, and traveling nurses help to alleviate it.

I myself have a 1/1 apartment on Davis Islands near the hospital that I'm considering renting to traveling nurses.The problem with rental arbitrage is that you need leverage as the renter to negotiate assignable lease terms with your landlord.

Another option if you are looking to rent rooms and there are hospitals in your area is to market to travelling nurses, using a website like https://www.furnishedfinder.com/  These are shorter term leases, usually about 3 months, and you are renting to professionals who are in an area for work.

It is not, it has limited application, and for travel expenses it does not apply at all.If you do not have a mileage log, you have to do your best good faith estimate and then pray that you're not audited.

I was able to travel down and see the property just before closing. 

I would like to convert the garage into a one bedroom and rent either to another long term tenant or mid term (30 day min for professors or traveling nurses).
