For example, they won't need to cover your personal belongings (furniture, clothing, etc.) because you won't be living there.A landlord policy should cost about the same as a homeowner's policy; it just changes what is covered.

a property that cost $140k has not had appreciation that has kept up with appreciation.  

I used to do essentially free consulting with new investors on it but gave it up for some of the same reasons - everyone thinks you can just sit at home and buy good properties across the country that are in great shape. 

I wouldn't recommend it for a number of reasons. 

Very few non-owner occupied property policies guarantee full replacement cost - they typically provide replacement cost up to the dwelling limit purchased. 

Which size of home is typically perform best on a cost benefit analysis?

And while yes, no one has the same pricing (combination of factors), I also continue to check on a regular basis our rankings and how we "present" on total costs per stay vs. our competitors.My gut says there is price creep and we might have a ways to go before the market really corrects.

Time and practice will still teach you as you do deals but it will help you understand what things costs for the size of the property 

-save $1k+ in taxes and fees yearly-can use the savings to get more insurance and a higher liability than the value of house. for flipping houses in California does anyone just put into sole proprietor own name and just use the $1k+ in savings for LLC costs into Insurance or use for savingor am I just being too risky. 

You would need an extremely high grossing property under market value on a something like a 5 year lease to profit, and you probably will not profit after startup costs until Year 2 or 3.Do not even think of trying it with 1/2 bedroom apartments or condos nor 2/3 bedroom homes.
