House hacking. How to calculate cash flow

[Michael Ashe]

What is the best way to calculate how much my primary home would cash flow as a rental?

Interested in house hacking but I've come to realize there are variables that I'm not aware of Like for example, I posted once before this and was informed property taxes increase when the home is converted to a rental.

 3 years into our 30 year on a 3.75% rate. Between appreciation and our payments we have 50K-75k in equity.

Check out how much you could make by looking into what others charge in your area and think about throwing in bonuses for folks who stick around longer or if you offer some cool extras. Then, figure out what it's gonna cost you – your mortgage, any possible property tax bumps, pricier landlord insurance, plus regular upkeep, fixes, and fees if you've got someone managing things. Toss in some extra cash for those times when no one's renting. Now, subtract all that from what you're bringing in. For instance, if you're thinking $2,000 in rent but have a $1,500 mortgage, $200 extra in property taxes, and $100 for insurance, plus a 5% chance of no one renting and another 10% set aside for fixes, your estimated cash flow might end up at -$200.
