A successful investor's time may be worth hundreds of dollars per hour.

If you have losses that high then it is worth your money to hire a CPA to prepare your tax return.

The property is worth approx. $900k, which would be almost $350k in equity today with $250k all-in for down payment/closing/rehab.

But then there are so many processes you have to go through that it isn’t really worth it.

How much will it be worth after its complete ?

Some firms (like mine) do have family office services that would incorporate everything you're asking for, but it may be overkill depending on your goals, net worth, and current situation.

Speaking as an immigrant myself, immigrants do not want any eviction record on their credit as they are trying to establish a life here, but I am not sure how to facilitate an eviction process for an international tenant with limited information on hand. 

Looking at the comps the property is worth about $100K in decent condition. 

This really depends how much you have invested on whether or not it's worth it and how much depreciation recapture he would be subjected to 

That leads to going back and forth on whether it's worth it given the upfront investment and the data we're finding on occupancy rates, cash flow, etc. vary from losing $5K/year to making over $10K/year.
