I'm looking do set up a workflow system for maintenance possibly using a Virtual Assistant or call center.

I plan on starting my BRRRR venture in North New Jersey.

Anything to be careful of before taking on a new home house hack venture?

You need two things, deal flow and capital. so each week or month, set actions that work towards creating deal flow and capital. focus on that. read books and learn those topics. this is just an example, but this is the thought process i have been employing. its easy to get distracted on other aspects or ventures since there are so many different approaches to real estate. 

My husband has an active LLC for his side business, but I am curious if anyone can recommend any books, podcasts, or other material so that I may understand the tax laws and how to be creative (legally).I'm not sure if I should plan to create my own LLC or if I could use his LLC for two opposite business ventures.

If you are told that you take on too much liability as a GP, ask "why not as a joint venture"?  

We are contemplating either adding them to the deed (and incurring those closing costs) or separately entering into a joint venture agreement  whereby they will gain a contractual right to 50% of the profits from the project in exchange for paying 50% of the costs, etc. 

Essentially, your joint venture ("JV") Partner will likely need to qualify as a co-borrower and co-guarantor (if you are buying the property in your own names and will have your individual names on the deed).

Our company Joint ventures on over 150 flips a year and we go by the above process all the time for success.

I went in on a joint venture contract with a partner to help me through my first investment wholesale deal.
