Imagine thousands on businesses deciding to conduct business as sole-proprietors and partnerships instead?

Being a sole proprietor or an LLC or an S-Corp will not matter.

Previously this would have been deductible, subject to limitation, on the taxpayer's Schedule A.A home office deduction for a sole proprietor and an owner of rentals whose rentals rise to the level of a trade or business, and has no other primary workplace most certainly remains deductible for the 2018 tax year.

You business is just a "Sole Proprietor" Bill's advice was right on

If the LLC is truly disregarded (meaning it does not file a tax return and is taxed as a sole proprietor) then the LLC and account closed are considered to be one and the same for 1031 purposes. 

In your case it sounds like you're wanting to form a single member LLC (you and your husband or actually your joint return as the tax payer) that will be taxed as a sole proprietor. 

Google: Sole Proprietor's status as a covered employee for a state form where a declaration can be made about Workman's comp.  

So I currently own one rental property I own and manage through an LLC where I am the sole proprietor.

Working as a contractor is no different than someone who works on 1099 (construction workers, proprietors, etc) - they get loan approvals all the time.

I know it would generally be in my best interest to get it contracted up myself--but I was thinking to let him negotiate their price and give me just a commission on the first few ones so I can hear how it's done.Should I open up an LLC or is acting as a sole-proprietor better?
