Mobile home park formula question

[Richert Dart]

Have a deal that has 6 owner occupied tenants at $190 per month. It is zoned for up to 15. My question is do I base my valuation on # of occupied x 60 x 190 or 6 x 60 x 190?

Or do I do 15 x 60 x 190?

Either way I have a good deal, just want to make sure my offer is correct.

Thank you.
