I do have an amazing lender in Phoenix who writes mortgages on non-commercial rental properties all day.

Same reason I am in the process of liquidating all non-commercial in the Peoples Republic of California.

I am not 100% positive how Zillow handles RENTAL properties for their site however for SFH’s (non-commercial) a homeowner can simply create an account, post pictures, write a description, and sell their property - for free.

Saving tax returns, selling my car and driving a beater, and living like a peasant. 

Non-commercial buildings are depreciated over 27.5 years (very slow) and land is not depreciated at all (zero benefit other than offsetting eventual sales proceeds when you decide to sell).

Any chance you'll ever want to refinance them at non commercial rates and transfer them to your name? 

Cap Rates don't truly apply to non-commercial loans, but if you show a track record of good cash flowing properties, it cant hurt.  

Note owner occupied LTV (95%) versus investor LTV (80% is SFR, 75% in non-commercial MF) implies that your current cash on hand can purchase ~4X more expensive local than it can OOS (5X in non-commercial MF).

We are real estate investors from CA looking for buy & hold properties, preferably SFR, MFR (non-commercial). 

So then I would rehab the property, gain some equity, and then refinance the property taking out the entire amount owed, pay off my HELOC, pay off my nice small 30 year fixed mortgage, take out another nice slightly larger but still cheap 30 year mortgage, and collect rent from peasants until the day I die.
