I use a wet finger, cup of water handy to dip the finger each time, and rag to clean the finger each time.

I work in CA as a land use/planning and site Civil Engineer (think roads, grading, sewer lines, water lines, curb and gutter, storm water drainage ect.) 

That will tell you what most would expect.When I bought a rental house earlier this year in a new area, the realtor/property manager told me that it wasn't expected for me to provide a refrigerator or stove much less washer/dryer, so you might be surprised what is the norm.Beyond your direct question, though, I think you need to reconsider your plan.  

If you post all of the following items here, I'll post an evaluation of hold vs sell from my perspective.TaxesSewer and Water (generally paid by tenant)Trash (generally paid/dealt with by tenant)Heat/Utilities (generally paid by tenant)HOA (probably not applicable)Cap Ex and Ops (my personal minimum is $150/roof/month)InsuranceMgmt Fee - as a % (general consensus here on BP is 10%. include it even if you think you are going to self manage)Vacancy- as a %. (8% represents 1 vacant month/unit/year)

@Jesse Waters  @John Thedford I really like the idea of including a large earnest deposit such as 10% or more but could you explain that further? 

@Starr Ango don't forget when you buy and hold you need a capital reserve to repair the roof, replace the hot water heater etc as things come up.  

Turns out my roofer screwed up, water was able to get under the shingles and ruined the kitchen ceiling. 

I knew that the wear and tear on the property, and water usage (which I pay for) would be lower with only one or two people rather than 6.

The manager that handles the bulk of my portfolio gave me a discount from 10% to 8% once she started managing more than 5 units for me, cutting that cost by 20% for doing business in bulk.Hope that helps, best of luck.Jesse Waters
