Formula for vacancy rate on multiple houses>?

[Patrick K]

What would be a standard way to calculate a vacancy percentage on multiple houses across a portfolio for an entire year, based on days vacant?

Seems standard and easy but I am finding conflicting answers. Thanks-

I echo 8%. -- If you can use 16%, I'd strongly encourage that because it adds a buffer. 2 months and one eviction and you're at 32% so 16% is not a stretch. The problem with being too conservative of course is that by the time you're done, the spreadsheet tells you that you can only pay 9K for a house! haha!!

All in all, 8% will NOT steer you too far wrong one way or the other. In fact, I'd say 7% is the LOWEST to go, which would represent 12 months occupied, followed by 1 month vacant (i.e. 1 out of 13 months vacant)
