@Derek Sperzel, If you and your wife file a joint tax return then you and she and those single member LLCs are the same taxpayer (as long as the LLCs do not file their own tax return). 

., (1964) 42 TC 1067.The Supreme Court has explained that the distinction between co-owners of property and partners depends on whether they intend to and, in fact, join together for the present conduct of an undertaking or enterprise-The following factors are often cited as evidence of this intent:The agreement of the parties and their conduct in executing its terms;The contributions, if any, that each party makes to the venture;Control over income and capital and the right of each party to make withdrawals;Whether the parties are co-proprietors who share in net profits and have an obligation to share losses;Whether business was conducted in the joint names of the parties;Whether the parties held themselves out as joint venturers; andWhether separate books of account were maintained for the venture.The court held that the co-ownership arrangement constituted a partnership for federal tax purposes.

Your best option is to find a partner to joint venture with.

I have properties held in my sole name that I want to contribute to an LLC owned jointly with my spouse without tripping transfer taxes in Nevada.

Just like when you take that ring off your finger it doesn't mean you are single.If you want to put two people on the lease say they are jointly and severally liable and have both sign as tenants.

Joint Ventures was touted as a way to do it with no down payment.

We were thinking of creating a joint bank account which we can combine our cash together and use for future traditional rental properties as well as Airbnb/Verbo properties.

Does this include joint ventures?

Your lease should have a "joint and several" clause, which basically says every tenant is 100% responsible for the rental.
