No other product can allow one to do this (HELOCs are similar in a sense but have drawbacks and limitations that whole life does not).I can tell you misunderstand the underlying mechanics of IBC yourself in how you mention credit (you're not alone!)

However, I feel like there's a lot of potential to run into a lot of walls/pitfalls that can cost a ton of time/money if I do this route.At the end of the day, I want to put a lot of emphasis on using the newest technologies to streamline the business as much as possible. 

Would it be possible to file a mechanic's lien on your own property and would this be a way to discourage potential title thieves?

You guys put to much emphasis on structure and not enough on the operator and the assets...

We are in the Seattle market, so reality is that demand so significantly outweighs supply that on new construction you aren't really at risk of not selling, its more for at what price per sq ft it will end up selling for.But one mechanism build in is that there is a $100k buffer where he will hold at least $50k of his build fee until after house is sold.

The cost starts with  1.) plan cost (survey, civil engineer, site plan, architect, structural engineer, mechanical/electrical/plumbing (short for MEP) plans, etc.).

Or "have a few good go to vendors for handyman, mechanicals etc

This week I received my first negative review from a guest.I understand that this is part of the business, but I'm just wondering what coping mechanisms does everyone revert to when this happens?

While your credit score matters in the real estate investment space, borrowing is more relationship oriented and greater emphasis is placed on the collateral. 

Unfortunately many investors become laser focused on the 100% recapitalization of their transactions and end up working harder than those who don't place all of their emphasis on the 100% capitalization and have real estate portfolios that perform better because they made investment decisions better aligned with the underlying real estate's fundamentals.
