Three things:Appraisers can't compare SFRs to duplexes any more than they can compare duplexes to space ships.

Right now, I am getting 2/3 times to return on my investment compared to QRP.

You should speak to a lender first and see if how much in loans you can qualify for and then compare that amount to the neighborhoods and property types in Los Angeles.

it costs about $100k to break ground on a SFR in San Diego.  

If you compare like for like, sfh are more profitable.  

However, one partner is hands on, lives in the area, and will be doing all the ground work; to include securing the financing, finding the deal, and self managing the property and everything that comes with that.

Don't compare yourself to others and find what works for you.

Again, I am completely unaware of comparable offers, however this duplex seems to have many really wonderful amenities and it is newly refurbished.

If you expect to eat, expect to hit the ground running, be a self starter, and ****ing close!

Nothing compared to property purchase cost increases over the past few years.
