My recommendation is still going to be the same as I've put in other threads; buy 1.25x DSCR in a very good area or up & coming area of a very good city ideally through BRRR(you'll keep 10-30% of the capital in the deal likely), invest ideally 60-80% of your downpayment(no less than 33%) in a debt note fund that matures in 2-4 years.

Ideally I would like the rent my property for the next 2-3 years.

I have two rental properties that my CPA thinks a cost segregation would be ideal for.

They can cover up to 90% of the purchase price and 100% of rehab costs, making them ideal for BRRRR projects[1].

What should the "ideal" comprehensive check list include?

This ensures the property performs well even under less-than-ideal circumstances.If a property doesn’t align with your goals, it’s perfectly fine to move on.

So if lots of parking, ideally walking distance to busses or transportation to cut down on cars, you might get away with it (legally).Operationally;  this is a can of worms to manage. 

I am looking for recommendations for a stacking washer/dryer and gas range, ideally something that will hold up to renters for a longer period of time.

Prepared to hold for 8 years, ideally 10-12.

A duplex, triplex, or fourplex is ideal because the more units, the more financing options banks may offer.
