Granted I am a newbie at this and just starting all my research on the subject (so be gentle). 

Using your list I corrected and listed in order of lowest rate to highest without giving rates as that changes daily and depends on mortgage middle FICO/vesting/down payment/property typeFHA Owner Occupied/ Low Down 3.5/ Lower FICO to 520/ 1.75% PMI permanentVA –Owner occupied/ must be Vet zero down no MI/ lower FICO 500Conventional – Owner or Non-Owner sold to Fannie or Freddie rules vary by lenderRefinance – Conventional 80 or 75 % LTV Cash out or 97.5 no cash out::: Traditional --> you need income documentation as in W-2 or IRS taxes with net income to qualify generally 43 % or 51% case by case::: there are some Foreign National programs with more down payment:: you supply Canadian Revenue returns and need to move money into US bank account etcNon-tradition --> not sure what you mean hereNon-QM --> Qualify with 24/ 12/ 1 bank deposits ::: or property cash flows with rents appraiser verifies::: or other twists and turns::: need good FICO 680+ and down payment loan sold to investor or held::: you go to a mortgage broker who has 20 possible sources and they are skilled at packaging your star shaped parameters to fit into their triangular shaped rules.

Decorating is a skill, and takes time as well.Start with lower rents and gently increase over time to get renters early on when you have no reviews.

Buy a gently used car. 

It is similar to rent by the room for residential but with a commercial twist.

should remain quite strong in my view - the interesting twist is that values are so high its hard to cash flow, but the typical solution people have been moving towards (short term rentals) are tough in Nashville since STR regulations are so tight.

Then and only then can we call the police (non-emergency line of course) and invite them over and then we have a reasonable discussion about it until we all come to a reasonable solution.If we are NOT home then we are supposed to knock on the door, gently of course and if the squatter does not let us into the property that we pay the mortgage on, then we are to calmly leave them alone, and continue paying the gas and electric and water bills and order food in to them three times a day either through Grubhub, Doordash or Postmates.

Grout a small area, wait 5-10 minutes, gently sponge off excess grout, rinse sponge, and repeat rinsing until all excess is gone.

As mentioned before, the risks of tenants moving their own appliances, causing damage, getting injured in the process, or improperly installing (think gas range leak) is another liability to worry about.You can easily buy low to mid end set of appliances gently used or new at a outlet type store for less than a months rent, which would have likely prevented or shortened your vacancy time in this case and thus payed for itself.
