New to STR questions

[Ted Caputo]

I am researching STR and multi-family. I just watched a video by Avery Carl on STR analysis and had two questions.

1. As she was determining gross income she used average daily rate and multiplied by 355 days. Isn't that very aggressive?

2. As she calculated down payment she used 10%. I thought less than 20% triggers PMI or other expenses? Are there different rules for "second homes" as compared to primary? She mentioned that she would use the property personally a few times a year.

She was analyzing two of her own properties so she may actually have 355 days occupancy? I have been looking at year round destinations and seasonal destinations and try adjust accordingly. I'm usually very conservative with year round and figure at 70% occupancy. I have also asked Property Managers for occupancy rates and will have to try Pricelabs and/or AirDNA.
