Some of the stilt homes are so far above the water, flood insurance doesnt seem necessary and the newer homes with newers roofs and impact windows should protect me. 

Take the age of the major mechanicals and roof etc and find the cost.

I know the useful life left on the roof is short, so I am hoping there is some negotiating around that.

Hard to find a "freedom ticket" like it that allows you to quickly go from broke with zero experience to racking in five figure checks from anywhere in the world.

Your capex will depend on the age of major things on the property like HVAC and roof, vacancy will depend on the market.  

When talking cap-ex, new-ish roof, new water heater, new central air system.

I undertand the 50% Rule is there to cover vacancies and repairs, but just about everything in the property is new from the roof to the central air, and I don't foresee any major repairs for the foreseeable future.

We have removed and replaced the roof, replaced all ceiling sheet rock and finished, to include replaced all enterior doors to date.  

I’ve seen brand new patios slope back towards the house, joist hangers attached with deck screws instead of nails, brand new roofs that leak, etc. there are a ton of hack builders out there creating problems for whoever buys the houses they build that’s why it’s recommended to hire an independent 3rd party home inspector even for new construction.
