Thanks again for your reply and if you have any further info to share I'd love to read it. use this analogy   people break the speed limit every day.. 

Regulation D allows for general solicitation of our investment/security which in the U.S. means we can advertise the investment anywhere anyhow but are limited to taking investment from Accredited Investors only.

You can refinance down below the conventional 20% equity lenders are limited to- Patch of Land (https://patchofland.com/), for both accredited and non-accredited investors, focused on up-and-coming neighborhoods, typical loan APR of 9-10% and LTV of 70%- Fundrise (https://fundrise.com/), for both accredited and non-accredited investors, advertised as better returns than a REIT, indicates the exact properties in the investment fund, $500 minimum- CrowdStreet (https://www.crowdstreet.com/), only for accredited investors, single property CRE equity crowdfunding

As long as you formally withdraw within the time frame allowed by the contract you are allowed.

This seems quite limiting if you're trying to BRRRR a property in under 6 months since so much of the out of pocket expense are the rehab costs which you aren't able to refi out of.Is it really as black and white of a choice as 1) wait 6 months to pull out the full 75% LTV or 2) if under 6 months only pull out the original cash purchase amount?

I've found some laminate/vinyl stair caps, but they're ridiculously expensive for what they are and we're trying to match the floors and the caps have very limited color options.If you've done something that works, would you have any pictures to show as well?

The primary question I have for the community is, “ should I withdraw from my fully vested 401k early?”

What should I have in place before buying <$50K rentals to limit liability and pay the least amount of taxes?

Contributions can be made as both employee and employer contributions (since you wear both hats):The employee contribution limit is 100% of your w-2 wages up to $19,000 (or an additional $6,000 if you are 50 or older) provided that you are not making employee contributions to another plan (e.g. if you have a day job with a 401k plan). 

As far as liability insurance is concerned, I would recommend the highest limits offered.
