I mostly build to hold.

It is easy to underestimate your rehab budget and your timeline leading to more holding costs.Or you could explore partnering with someone who has experience in the area and capital to also invest. 

We use Autohost to automate this process via an online check-in system: https://www.autohost.ai/You can also use it to gather additional information and place a hold on their credit card, similar to a hotel.The one downside of Autohost, is that it doesn't have an automated way to collect the ID for all the adult guests (although it collects names + email from the guest).Finally, Autohost can also be used to have the guests sign your rental agreement and agree to your house rules.

And what kind of deals are you finding as far as buy and hold or BRRRR deals?

I’m aware of what material participation is, i just wanted to see if anyone has personally done this and if there were any issues or pitfalls with doing it.buy a million dollar cabin, cost segregation, 200- 250k tax deduction against w-2 income and rinse and repeat?

Currently, when I include both refinance and sale proceeds, I get an unrealistic XIRR of 49%, while the average cash flow throughout the investment (7-year hold period) sat around 8%, and this seems incorrect to me. 

However, if your LLC has title insurance and you issue a warranty deed then you might be able to hold the LLC responsible for the issue and make the title insurance handle it, but if you use a quit claim deed that wouldn't work.

Find a value add duplex/triplex, invest in the renovation, refi, repeat. 

Quote from @Wilson Hunter: Now that I have Airbnb and VRBO traction on multiple vacation properties I would like to explore creating a direct booking website for family, friends, and repeat guests to book without all the platform fees.What are recommendations on website service that allows for (1) multiple properties (2) running transactions (3) synced calendars?

Never heard of a performance deed.Maybe have them sign a Quit Claim deed to you that your attorney holds in case they stop paying?
