Do they require anything special that a normal home wouldn't need?

I appreciate all of the information.My current home has a JADU and an ADU.

You know the property can be improved.

I am a first time investor, about to rent out my current home (3BR/2bath) as I move into a new one (so a tad nervous!).

Another concern I would have is that if we enter into an economic situation where tourism declines and foreigners stop buying expensive second homes there, you could get stuck with a property you can’t sell that isn’t producing much income. 

I was able to save a good amount of money and purchase a 3 bedroom 2 bath mobile home on an acre of land all cash, that property generates $875 a month, no mortgage or HOA fees.

I'm looking at finance options to purchase an entitled lot in Truckee, CA and build a SF modular home on it as an investment.

The home is in the name of his dead brother and he doesn't have a will supporting he is the owner. 

", but I am unsure if that only applies if we were to stay in the unit for less then 24 months.We would ideally like to live in the unit for 24 months, do some improvements and re-rent the unit at market rates, but Im not entirely sure what the rules are here.

My better half looked at my creation when we got home and named it "Lawnmower Mouse" for a reason.I hear you on the shades.
