@Alex De SousaThat is some great advice, although the part about raising the house is not entirely applicable to us.  

If I rent it I would want it in a Delaware single member LLC for liability protection.My question:1.  

The only strategy I see investors using successfully to work around the CA franchise tax is to utilize a Delaware Statutory Trust, which is considered a disregarded entity.

We have incorporated an LLC in Delaware. 

If the paint and flooring were each less than $2,500 on separate invoices, can I claim them as de minimis or is the cost of the renovation included with the painting and carpet and therefore the cost to the unit is over $2,500?

@Mariela De Leon If you are in City limits you cant have any mobile homes, period. it has to be outside city limits.

I am currently in need for some data from investors in the Philly and Delaware County Marketplace for rentals.

Places like San Miguel de Allende are awaesome places to consider for avoiding that Trust issue near coast and border.

They eventually will be de-indexed.

I'm also looking to connect with property sellers open to do TERMs in PA, NJ and DE.
