Ideally I would be renting them out using a triple-net lease so essentially all your costs are being passed directly to the tenant.

A commercial tenant may have a triple net multi year lease.

The buildings will be built ranch style, basically a duplex doubled or tripled/ mirrored to increase the number of units. 

If the applicants' credit or other background issues are in question, we may double or triple the security deposit.We do not request last month's rent. 

I've been to California once or twice and I remember the housing market being fairly expensive (At least when you compare it to NC) If I'm remembering correctly, I saw a house on the outskirts of San Diego that was worth about triple what the same home would have been worth where I'm at!

This about triples the next cash flow while minimizing the risks of a bad tenant or costs of fix-up.  

Single, double or triple net lease might make him change his mind.

We use triple ribbed sheets preordered to size from Metal Mart, and as little trim as possible.

Would it be triple this for a triplex?

So many kids who went off to college, but are having trouble finding a job, are either moving back home with the folks or doubling and tripling up in a place with others.
