If he’s getting 40 calls in one day, he should be charging more. I only left my e-mail, and got three serious inquiries the first day I ran my ad: a young professional, PLNU students, and some hippies.
They all seem fine to me. I don’t know much about PLNU other than it is very christian, expensive, and full of surfers. Sounds OK to me.
When I rented a cottage on an OB beach block, I did a walk by/window peak of the unit, realized it was extremely underpriced, and then immediately went to the property manager with a completed application, a cashier’s check for two months’ rent (which was not required) plus the security deposit, my last pay stub, and a printout of my credit report.
My rent was never raised so after a few years it got to the point that my cottage with two parking spaces and a small yard was $300/mo less than 1-bedrooms with no parking further from the beach on the same street.
