I think the DSCR route would be my option due to high DRI. 

High volume, fast turnover.

Just want to see if my quotes are not too high (i know it varies by places).

High Supply and High Demand. 

My name is Ethan, I am a brand new college student and I have been kind of stunned by what I have heard on BP, as I have listened and read books through High School.

I'd also highly recommend doing the following:1. 

Purchasing a home in Arizona, no realestate agent used, since it was a new built.what should I be on the look out for, any Arizona Title company highly recommended, and escrow companies if the seller does not choose one?

Yes, I have been all over Airdna and Zillow for a while now and it seems as if the ADR just isn't high enough to justify the cost of the homes if I wanted to buy a house and set it up as a STR.

The only other way to ditch PMI would be to refinance into a conventional loan however it wouldn't be worth it with the high rates today. 

I highly recommend them if you're looking for a good roofer in the Phoenix area.
