@Mark Moore , some of your numbers don't add (or multiply) up.--$875/month is $10,500/yr not $10,800--those maintenance and management expenses seem very low.  

What I usually do is take the most recent 3-5 properties and do an average price per square foot and then your subject property multiply the square footage by your average price per square foot - this should get you close to a comp price.  

@Jonathan Baptiste cool story glad you learned a lot.Now, multiply all that by 300+ tenants and you'll know what the average PMC has to deal with!

Log how many hours you spend doing this and multiply by whatever you believe your hourly time is worth....then see if you actually saved any money DIY..........just sayin'

I've heard people claim things like 70+% APR because so much of their payment is interest.A lot of people don't understand that interest is ALWAYS calculated as outstanding principal multiplied by interest rate. 

What us "regular" people do is we take our gross rent and then multiply it at 85% or 80% (depending on what metric you want to use) and THEN we calculate our cash flow.

You’ll be eligible to buy another house hack sooner (multiplying your net worth building machine).You can refinance if rates drop in 6 months to a year.

House-hacking will be uncomfortable, and that discomfort is multiplied when you live in an unfamiliar place.

Multiplied by 3-5 bedrooms and that gets real expensive. 

If you are writing off the building, then your would multiply the cost by how much your using for business vs. personal use.
