I guess time will tell how accurate I was with predicting that. 

There are only the ownership and use tests.

It requires a thorough understanding of zoning/future use, the municipalities' building codes, soil testing/standards, impact fees and more. 

@Donald Kellogg make sure your vacancy percentage is accurate for your market, 3% is great.  

It's not always accurate because I come across many properties that are being rented out and the county still says owner occupied.

The unit tested positive for meth and was condemned by the health department

I enjoy listening to the MB podcast, but I'm curious how accurate his calculations are for a passive investor. 

Calculated by dividing total revenue by the number of days a listing was available, RevPAR is a more accurate metric hosts can use to gauge a listing’s profitability.During the 2-week period from December 18th to December 31st of 2018, hosts in Orlando averaged a 73.35% occupancy rate.

I don't know if you can accurately budget for these expenses but I would keep them in mind.

For example, down here in NC, I paid $500 for a pre licensing course, $100 to take the test, and around $500 to join the MLS.
