I manage an amazing group of Philly landlords on FB and see a range of styles and approaches.

My idea is to expand the garage, expand the main floor and split it into a duplex style, then keep the basement as is. 

Hello i am moving out to another home (rental home close to my office) and planning to rent out my current primary 4Br town home style condo (located in East bay area, CA) .

I know I am not the Realtor for everyone, I have my own style.

And every investment style has a different return/liquidity/effort/risk/etc. profile.

Your website looks more investment oriented than dealing with tenant rights and eviction matters.

I'll look at any good cash flowing deal but I especially: groups of duplexes, ranch style properties, separately metered utilities, properties purpose built as multi (not a hacked up SFR), post 1950 properties, central AC, garages or carports, washer dryer connections in unit or building laundry, value add priced dated properties neighborhoods in lower tax areas, neighborhoods with no through traffic.

So YES, this is possible but you'd be limited to table funded local bank or CA based loan options who are familiar with ADUs or investment style loans if you want to refi once the ADU is built.

There are 2 or 3 different styles of keg tappers or sankeys.  98% of your kegs will use an American. 

I'm open to suggestions on some good reads even if they aren't necessarily real estate oriented.
