Multiply that by 12 for $17,550 yearly net income.

I agree with the pesticide company.I own 3 families, and occasionally I get a slob get in, bring in their own roaches, and thru lack of cleanliness, the pests multiplies, and from there move on to other units.

Multiply that by having multiple clients and it becomes exponentially more difficult for them to profitably dedicate their time for you.

To reduce risk, my goal was to save a 6 month runway of living expenses that would not be touchable — I told myself I could only invest any money above that 6 months of savings (if you know your actual monthly expenses you can just multiply that by 6 to get that number, @scott trench explains it in his book Set for Life).However, the BRRR method involved fronting a lot of cash in a new market, managing renovations from afar, and orchestrating a perfect refinance to get my cash back.

If you take the estimated appraised value on your house and multiply that by 80% (most typical), 85% or 90% (usually the maximum a lender will go and the higher Loan-To-Value you go, the fewer lenders you have to choose from) and then deduct your first mortgage balance to see how much equity is there to lend against. 

Take the amount you charge each tenant and multiply this by 12.

Is that usually the multiplier used for this market?

Money Mustache, the modern godfather of the financial independence movement, has this very simple calculation that was quite helpful for me in understanding the real costs of property management: take any fixed monthly expense you have and multiply it by 173.

I imagine this issue arose when you went from 1st of the month payment, to 15th. what you need to do is track down all your payments and track your timeline of living there. calculate how many months and how many weeks you were there, and multiply that by your rent payment. if that is not equal to the total amount of money given to them, then you owe them money. as a side note, if you moved from 1st to 15th due date, there has to be a check where you gave them half a month rent, or one and a half month rent. if you only have checks with the total rent due, then I am 99% sure you missed something.

@Adam Philpot, interesting that you estimate the price by a multiplier.
