I understand what the standard down payment percentages are for jumbo loans for a given credit score, but does anyone have any insight or advice on who or what I should consider next?

Our transfer fees, title fees, etc. responsibilities will be the standard defaults. 

Are there insurance companies that offer this solely?

This is my first major remodel project with a GC, so I don't know what is standard.

Total loan is limited to FHA loan limits for the county.Also includes mortgage insurance premium just like a regular FHA loan.203k takes longer to close that a regular FHA loan, which can impact the strength of your offer.

Our insurance agent was working on getting us some sort of blanket policy that covered up to the purchase price only, but he's having difficulty because we often have mobile homes.

That means the 15% down investment property taxes two full discount points to get the same rate as the 25% down standard.

Medicaid issued AL allows for housing, insurance, guardian and attorney fees if any, and a PNA, and community spousal allocation if applicable.  

Taxes, insurance, vacancy, eviction costs, repairs, maintenance, property management, accounting, etc. 

I've looked into them in the past as they would work well for me with low money down, i heard before that you had to pay monthly loan insurance(think it was around $100) and got nervous about it cutting into my cash flow to much.
