I grew up in South Everett on the other side of I-5 and currently live North.Proximity to an airport may make traffic bad and add a little noise, but I don't think it hurts the rental demand in that area at all.

I would like to leave the existing doorway and framing in tact.The main objective is to reduce the noise between the two rooms.

I know it's going to be a grind and there's lots to learn and experience, but I'm ready to get started!

It truly comes down to how much hustle and grind you have.

Not true - They call landlords about noise, fights and lots of other things. 

Buyer would want to refinance ASAP assuming the seller allows an early payoff w/o a penalty. we are pulling out the old tried and true techniques that we had to use to grind through our deals back in those days..

(These depends on how much you want to provide) Linens (people generally underestimate linens big time, depending on your type of STR there can be high turn over of linens) Software (smart pricing, video monitoring, automatic messaging, PMS, noise monitoring).

Yes, it would include removal of trees, grinding every stump and haul away everything.

I am confident in my numbers and my ability to grind to keep my business alive if things get tough.

My concern is whether the Airbnb guests tick off the long-term tenants by making noise or creating problems.
