I don’t have time for games and dislike when loan representatives act like they can’t ball park me a loan estimate.

Identify the vehicles in the parking according to the units. 

It has one STR penthouse (5 bdrm 4 bath with 3000 sf roof terrace),  plus 5 duplex units (Each duplex is two 3 bdrm 2 bath). 22 parking spaces.

If affordable housing is your priority for your strategy going the building rout in California may not be as beneficial as buying something you can rehab.

Meanwhile that capital is not put to work, unless they park it in stocks, bonds, mutual funds, etc which are subject to market volatilities and shouldn't be used for shorter term investment horizons. 

I do mobile home parks.

Are trailer park homes good investments?

There can be shared laundry onsite, shared parking, shared (yet separated) yard space etcAs for the math portion, I run my rental comps on rentometer and compare it to other ADU's or 1/1 units and their rent amount.

Same if you park it (your cash, not your ride) and not use it at all. 

It is a 5br house in southwest side of portage park for $350,000 and each bedroom will rent $800-900 range from comps we found.
