For me I follow the regiment of proper leaders and downspouts to get roof water away from foundation (to include regular maint thereof) proper grading to exterior of home (to include regular maint there of), window well covers ( to include regular maint. thereof and if I even suspect water penetration through the walls and or floor a complete french drain w/ sumps goes in immediately.

This time though, be sure its a commercial grade ozone machine. 

As a result, lower grade, less unique, more "average" properties are suffering on their platform.Not saying you shouldn't go for an STR, I'm just saying it's a tricky and risky market to break into right now, and there are much easier, less risky strategies for beginning investors (such as house hacking, or running your multifam property as a LTR).Good luck out there!

I did go to the tax assessment page which gave the house a D grade and condition of average. 

Also type of foundation (slab on grade, spread foundations, etc.), and age of the house. 

There is a reason people begin in the first grade and don't start school in high school.

Basements shall not be used for sleeping purposes unless they conform to the specifications of this code and the required minimum window area is entirely above the grade of the ground adjoining.

This question seems a bit too general, numerous variables:* The grade of the neighborhood* The grade of the property* The ability to obtain optimal financing on the property (i.e. long-term low fixed-rate from Fannie, for example)* Area supply/demand of renters - current and projected* Area supply/demand of investors* The size of the complex - at a certain point the large institutional money is a buyer and this drives down the cap due to their very low COFSo range would be 6% - 12%.

Keep in mind most voucher recipients can be selective enough to live in a c grade area and hence d grade will equate to low credit score market tenants. 

Bathrooms are a big deal to renters that have options so you want it above “obvious rental” grade—and remember your exit is going to be to an owner occupant.
