:40-60% gross revenue (after cleaning fees) for either 2 years or until the investment is recouped then 5-15% cut in perpetuity. 

This way you do not need the 20% down ($3000,000 x .2 = $60,000) in order to purchase a non-owner-occupied triplex. 2.

I worked alongside professionals as a "helper" With pretty much no construction experience, they put me on the dirty grunt work, cleaning rat poop, removing the old toilets, scrubbing down baseboards, etc. but as I was doing that, I was watching every single thing they did, and pestered them with tons of questions on how to do things and different techniques.

Outside of my very first purchase which is a duplex that I house hacked, I a very proud of my first non-owner occupied property.

The non ionIzIng radiation you speak of is not issue unless you are literally standing right in front of the antennas.

I tried to overcome that objection by explaining that, unlike a LTR, STR's are professionally cleaned almost weekly and during that time they are inspected for damage and if any, repairs are made immediately.

I would definitely suggest a "wood flooring" on the stairs instead of carpet for the cleaning reason. 

Some of the comps in the area are around $100,000 this property is move in ready clean and ready to rent, previous rent was $900 and as high as $1,100

The LOIs I work with are non-binding, and I want to bind the Seller.  

Vacancy overall is probably around 8 percent but good clean housing can go fast
