@Cody Mau Right now its a house hack and the income covers the PITI (ex vacancy and maintenance) which isn't bad for the area.

For Multi family >5 units should be 5-8% and flat fee (50-200) to fill a vacancy. 

I am looking for if you were comparing these two what would make you lean one way or the other- ex. how much does the good vs not-so great school zone affect you when looking for quality tenants, vacancy rates, CapEx on a 2000 build vs 2017, etc.

The hotels have vacancies, I check them out every day. 

There are many locations in NH west of major cities with appealing vacancy rates and low prices.

So, using the above as a guideline any vacancies I have in the next 14 to 30 days I drop to 3 night minimumAny vacancies I have less than 14 days out I drop to a 2 night minimum.If you have a default 2 night minimum you will see a lot of your weekends getting booked up far in advance leaving you with weekdays to fill at lower rates.I do not recommend allowing 1 night rentals.  

Question: what is the best way to estimate daily rent rates and vacancy numbers?

And will the market in Central Oregon fall as hard as other places where rents have gone too high for people to afford.Will there also be less vacancy due to more affordable rent?

I typically use 8% vacancy in my underwriting.

We want proof of financials to to mostly see vacancy rates they've experienced to compare the utilities (all utilities are included in rent and paid by owner) and make sure our numbers are close because 2 of the units are rather small and are high priced for the area (again, based on their current rental price claims).
