BRRRR Investing: External Rehab and ARV

[Drew Bursey]

I have a few questions regarding BRRRR

I am looking to purchase a triplex and is full. 

My first issue is that I can't find any triplexes that have sold in the area for the past two years.

What would be a comparable house to a triplex?

Secondly, I don't really want to kick the tenants out while I rehab the property. Based on the pictures, the inside looks good. 

I was wanting to put a new roof, siding, windows and septic tank.

Would external rehab improve the ARV a lot?

Thanks
