The main issue with rental basement is water if it has water issue usually it is a simple fix .Clean gutters ,discharge gutter  water away 10" away from foundation, make sure you foundation soil is slopped away from it .If you need to buy soil get a clay mix .Cut back any tree too close to the foundation look at the drip line that's how far the limbs are out from the tree .If all that is done still has water buy a sump pump  carry the water to day light away from foundation 10" to 15" .

My assumption has been DSCR is the main driver, coming from my institutional experience (larger deals) we usually target a 1.2 and over DSCR.

SPC is great for moisture-prone areas like kitchens and baths, while WPC is softer underfoot and ideal for main living areas.

That is one of the main areas we serve in CT.

For example, you are looking at a four bedroom house but you can enclose the dining room into a 5th bedroom.

As for noise, that is most likely going to be in the main living room or outside.
