He replaced some interior parts and we were good to go. initially.Well, then my second crappy sub comes along and I hired him to do A LOT of work (bad idea, now I dribble work out to people in tiny doses.)

Say I buy a small duplex, on the same property could I build two more "tiny homes" and say the address was 235 a/b oak lane would it just be 235 a/b/c/d?

You will Not be able to borrow the down payment on a property from Any lender, let alone a HML, if you aren't putting up a Different property with no/tiny loan on it.

Got into my first house purchase in 2010, got involved with AirBnB since 2012, learned and built a Tiny House, been enjoying learning and renovating parts of my initial property purchase and involved in taking care of others properties (cleanings, airbnb/rentals, and maintenance).

There is always the tiny risk of someone following through on their threat to sue.

A 2001 Grand Caravan can tow 1,800 lbs and has a GVWR of 5,550 lbs, with a self weight of 3,999 lbs.A 2001 Tundra has 7,800 lbs of towing capacity, a GVWR of 6,200 lbs and a self weight of 4,644 lbs.Even a tiny 2001 Ford Ranger can tow 5,620 lbs.How is that minivan going to outperform a pickup truck, in any way related to rehabbing and maintaining real estate?

That is definitely not a law that is good for businesses especially small business that can’t afford automation technology .If someone owns a home that is paid off or a tiny mortgage and enough to pay living expenses they have little incentive to move especially with Prop 13 keeping their taxes low .

My realtors treated me with respect on a tiny purchase...I've helped them by simply telling others of the service I got.Look at my votes, I help here plenty.

Twist the math anyway you like but not taking a chance on over 100m for a tiny $2 investment is foolish to me. 

Wipe surface with TSP (1/4 handfull in 1 gallon bucket 3/4 filled water) using cotton rags (real cotton, not the non-absorbent stretchy stuff.)Dab latex (paintable) caulk or toothpaste into nail holes with finger (very tiny amount to just slightly fill the hole) wipe with dry finger, palm of hand or rag.When dry if there's still a sheen when viewed at angle then lightly "scuff-up" surface with 400 or 600 grit sandpaper wrapped around a 1x3x6" sanding block in long vertical sweeping motions.
