For example if you are inexperienced, don't have much time but have capital I would recommend avoiding ground up development for example.

In the design phase, I’m intentionally wanting to add features and value to later use as part of my long term funding strategy.

@Robert Ellis - Oftentimes buildings are zoned with ground floor retail to stimulate the growth of walkable "downtown" areas.  

For #1, I will likely use my agent and their team to help me close on a deal and be my ears and eyes on the ground, same way as I have approached conventional financing. 

You really need someone on the ground (maybe a partner) that can help you understand the market and drive for dollars to get off market properties and advertise to them. 

Hey BP,I’m managing 4 units for a distance and am trying figure out the best system or solution to the keys.My first thought is to have a boots on the ground person I can trust to collect keys and take pics of units when tenant leaves.

I imagine one floor and ground level a space for parking. 

And for #4 that means that if you're counting anything below grade (ground level) towards your required living area, there have to be windows and the ground level has to be halfway down the wall or lower.

Since we are building from the ground up, what are some of the amenities that you would add that would make this future listing more attractive to vacationers?

I'm currently in the process of getting my Hamtramck duplex house hack up and running, I'm currently in the tenant screening phase.
