Excellent, you took initiative and did something very difficult for most people.  

If the sales price is $850k you will need significant down payment to carry the DSCR loan on $5300 current rents...check in with @Joseph Chiofalo  as DSCR loans 5+ units are typically a bit more difficult to place as well. 

The combo of the current rate environment, the current prices of most properties, and the current rental market makes cashflow much more difficult these days that it was a couple years ago.

If yes, it will be difficult to be a part time agent if you can only work at night and weekends (meaning phone calls, texting clients, showing apartments, writing up contracts, etc).

Is it difficult to get it zoned as duplex later? 

The idea is to simply not own anything in your name, but control everything, and making it very difficult to collect a judgment.

However, it’s a difficult economic time and I still believe in the portfolio.

You WILL get several bad apples.a few short term rentals (2 or 3) may be doable, but you still would be trying to find good tenants fast, which is difficult.

Yes this is a critical reason why self managing out of state is very difficult to execute. 

Without owning rental property personally, it is difficult to truly understand how to minimize costs and maximize your investment.2 - Who do you deal with?
